Easiest way to access MySQL from Django on Mac OS X?...

2012-09-22 Thread Fred Stluka


Django users,

What's the latest on the easiest way to access MySQL from Django
on Mac OS X 10.6.8 (Snow Leopard)?

I've Googled lots of info, but some may be outdated.  Seems to be
more complicated than it should be, especially since everything else
to do with Django has been so easy.

Here's what I've done and learned:

  - Followed MYSQLdb link in Django docs:
  
https://docs.djangoproject.com/en/1.4/topics/install/#database-installation

to:
  http://sourceforge.net/projects/mysql-python/
and downloaded:
  MySQL-python-1.2.3.tar.gz
  - More info at:  http://mysql-python.sourceforge.net/
  - Confirmed it is not already installed:
% python
  Python 2.7.3 (v2.7.3:70274d53c1dd, Apr  9 2012, 20:52:43)
  [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
  Type "help", "copyright", "credits" or "license" for more 
information.

>>> import MySQLdb
  Traceback (most recent call last):
File "", line 1, in 
File "MySQLdb/__init__.py", line 19, in 
  import _mysql
  ImportError: No module named _mysql
>>>
  % gunzip MySQL-python-1.2.3.tar.gz
  % tar -xvf MySQL-python-1.2.3.tar
  % less README
- Lots of caveats.  Has to be built and installed.  Looks ugly.
- Says it requires setuptools Python module.
  - Confirmed setuptools is not already installed, by trying the import
 statement that setup.py is going to do:
% python
>>> from setuptools import setup, Extension
  Traceback (most recent call last):
File "", line 1, in 
  ImportError: No module named setuptools
>>>
  % python setup.py build
- Got error, as expected:
Traceback (most recent call last):
  File "setup.py", line 5, in 
from setuptools import setup, Extension
ImportError: No module named setuptools
Exit 1
  % sudo python setup.py install
- No.  Didn't try.  Not yet built.


So now I need setuptools first.  Am I starting down a long dependency
chain of installs, or will this be easy?

I have a Linux server, where it appears that I could use yum to do
a painless install:

  % yum list all | grep -i mysql | grep -i py
MySQL-python.x86_64 1.2.3-0.3.c1.1.8.amzn1  amzn-main

Perhaps there's an easier way for Mac OS X also?  Did some more
Googling and found:

 
http://stackoverflow.com/questions/1448429/how-to-install-mysqldb-python-data-access-library-to-mysql-on-mac-os-x


which is a longish manual set of instructions by an author who wishes
there were a better way, but another reply says to just use MacPorts to
install it.

Any advice?  Thanks!

Re: Easiest way to access MySQL from Django on Mac OS X?...

2012-09-23 Thread Fred Stluka

Resolved this on my own. Here's what I did:

- Downloaded and installed MacPorts, but decided not to use it
because I have too much software already installed that
MacPorts doesn't know about and wants to reinstall (MySQL,
Python, OpenSSL, etc.)

- Downloaded and installed Python setuptools and resumed the
MySQLdb setup that I'd already begun (see my previous post
appended below). It turned out to be easy:
- Download setuptools-0.6c11-py2.7.egg from
http://pypi.python.org/pypi/setuptools/
% sh setuptools-0.6c11-py2.7.egg
% cd MySQL-python-1.2.3
% python setup.py build
% sudo python setup.py install

Success! Now I can access MySQL from my Python/Django apps.

BTW, I also downloaded and installed PyCharm. Nice Python IDE!

2012-09-23 Thread Fred Stluka


Andrew,

Good info.  Thanks!  I'm hearing lots of good things about Homebrew.
If I go to a package manager, I may try it instead of MacPorts.  For now,
I've succeeded with just installing setuptools and MySQLdb, as described
below, and not re-installing MySQL or Python.

I installed MacPorts, but decided not to use it after doing a dry-run
and seeing that it was planning to re-install a bunch of stuff that it
doesn't know I already have installed and configured:  MySQL,
Python, etc.  Seems like MacPorts is too intrusive if you don't use
it from day one for all Mac installs.  Homebrew would have the
same problem, I guess, as do yum and apt-get on Linux.  It's hard
to start using any of them after a couple years of configuring the
system manually because none of the packages you already
installed are recorded in their records.  I may start using Homebrew
the next time I configure a Mac from scratch, just as I now do all
of my Linux boxes via yum.

For now, I did a manual install of Python setuptools, and then a
manual install of the MySQLdb driver for Python.  Everything's
working fine.  Turned out to be as easy as:
  - Download setuptools-0.6c11-py2.7.egg from
http://pypi.python.org/pypi/setuptools/
  % sh setuptools-0.6c11-py2.7.egg
  - Download MySQL-python-1.2.3.tar.gz from

  % gunzip MySQL-python-1.2.3.tar.gz
  % tar -xvf MySQL-python-1.2.3.tar

When I'm setting up a new Mac OS system, the process I go through to
install Python and MySQL.

First, I install Python using this guide:
http://docs.python-guide.org/en/latest/starting/install/osx/
The guide also installs Homebrew, which works great for me so far and
is easily removable.

After Python and Homebrew is installed, then you can install mysql with:

brew install mysql

This will get us the proper headers we need to install MySQLdb with
pip. After MySQL is installed, you can install MySQLdb into a
virtualenv or system-wide with a simple command:

pip install MySQLdb

Hope that helps,

Re: send_mail on MAC OS X 10.7

2012-10-03 Thread Fred Stluka


Cheng,

Yeah, there's probably no need to be running sendmail on the Mac
if you only use it as a client machine, not a server that accepts
incoming mail requests from other machines.  Just configure Django
to use an SMTP server somewhere in the world that you have rights
to use, like smtp.googlemail.com as you do with your Apple Mail
client.

If you know the right SMTP server to use, then simply configure django
to use it:

Re: Edit two related models on one form

2012-10-06 Thread Fred Stluka


Felix,

I'm new to Python and Django, so others may be able to improve
on this, but I had a similar scenario recently and this was my
solution.

I used 2 ModelForms in the same HTML template.  My view method
looks something like (edited to use your question/answer instead
of my original donor/donation objects):


def question_and_answer(request):
"""
Show blank question and answer form, or save question and answer,
or re-show form with errors.

Handles 3 cases:
- Show empty editable form for new questions and answer (GET)
- Save details for new question and answer (POST, valid form)
- Show errors/re-prompt for new question and answer (POST, invalid 
form)


Does not allow edit of existing question or answer.
"""
if request.method == 'POST':
answerform = AnswerForm(request.POST)
questionform = QuestionForm(request.POST)
if questionform.is_valid() and answerform.is_valid():
questionform.save()
answerform.instance.question = questionform.instance
answerform.save()

return HttpResponseRedirect( ... )
else:
answerform = AnswerForm()
questionform = QuestionForm()

return render_to_response(
'question_and_answer.html',
{'answerform': answerform,
 'questionform': questionform,
},
context_instance=RequestContext(request)
)



You'll have to enhance the above to support multiple answers.
Also, to allow editing of existing questions and answers.  I have
code for that scenario too, if you can't figure it out, but this
should get you started.

Anyone else have improvements on this?

Hello,

I have a pretty basic problem that I cannot find any reference for to 
solve. Let's say I have the following relationship scenario: *question 
*and *answer*, where *each* *question* may have up to *four answers*, 
but *each* *answer* can only have *one question*. I concluded to put a 
/ForeignKey/ on the answer model.


The problem, however, comes when I want to add a new question. 
Currently, I would need to first add a question by itself and 
afterwards create new answers and reference the question. Optimally, I 
would like to be able to create the necessary answers right from the 
question form and associate them with the question upon saving. This 
of course also implies that upon load a form for a certain question, 
the already associated answers will be loaded.


Do I handle the form logic in a ModelForm subclass, on the view or is 
there already pluggable app for this that I missed?


Seems like this scenario would be a pretty common problem,

Felix

+1 for fail2ban

It's surprising that a 3-year attack eventually succeeded if you
had fail2ban installed, which should have blocked the attack after
just a couple tries.  Or had you not yet learned about fail2ban?
I got hacked once too, before I learned about fail2ban.  Never
since.

This depends on your specific security requirements. If you're mainly
concerned with protecting your server and website from unwanted
tampering, then the important things are 1) only allow connections to
ports you're using (HTTP) and restrict access via SSH to your IP or a
local network; 2) make sure the software you're using is secure (the
ones you mention are good; though I think Apache is vulnerable to
a type
of DDOS attack: http://en.wikipedia.org/wiki/Slowloris); 3) check your
own code; Django is good about security but that doesn't mean you
can't
build an insecure application with it; 4) choose good passwords, etc.
and if you're particularly concerned, consider using keys for your SSH
connection.

I've used both and haven't noticed much difference for the things
I do.
I would recommend nginx in place of lighttpd (better maintained),

Re: Help me choose OS for django server

Yes, CentOS is a good choice.  You can find all of the packages you
need at the EPEL yum repo.

First, is this a good idea?  Do you think I can do this securely using 
the django, apache, and lighttpd docs? or am I asking for trouble? 
 What are the major security issues I need to be aware of when 
administering a server?


Also, if I go this route, I'll need to choose an OS.  I'm running a 
production server (just Apache + mod_wsgi) using my Arch Linux box, 
but I don't think arch is the best idea.  I'm sorta trying to decide 
between CentOS and Ubuntu.  Leaning toward CentOS, but just a little 
worried it might be missing some of the packages I need.  I've never 
used CentOS before.  Any advice?

In the djangocon lightning talk there was mention of this disconnect

Not a problem restricted to django. I've been checking out a lot of
frameworks in different languages and most suffer the same malady.
i.e. everything works great locally but hauling it all into a production
env. becomes a project in itself.

It's hard to document because each env. will be different.


This is an interesting problem, which you can work around to a certain
extent. Making predictable and reproducible deployments of code is an
integral part of Software Configuration Management. SCM is a big
topic, so I'm not going to go into crazy details, but here are some
details of how we mitigate these risks at $JOB

1) Use virtualenv and pip

Virtualenv is essential. It allows you to separate the libraries you
use in your deployment from the any other python package. I recommend
using "--no-site-packages" to force virtualenv to ignore any system
site packages, but sometimes it can be necessary.

Pip is the other side of this. Pip is a simple way to specify python
packages to install. You can explicitly reference versions of
packages, or ranges of packages. Eg, "Django>1.4,<1.5" specifies that
the most recent release in the 1.4 cycle is correct. You can also have
a single file that lists all the packages required for your project to
run, usually called 'requirements.txt'. Pip will take that file, and
install all listed packages along with any dependencies.


2) Your project structure is code, and should live in source control.

Your project structure is all the files and folders that make up a
deployment, but aren't actual python code. Eg, if your deployment for
django project 'myproj' looks like this:

.
├── htdocs/
├── logs/
├── project/
│   ├── manage.py
│   └── myproj/
└── scripts/

The 'myproj' directory contains the project source code and is usually
version controlled. However, everything listed there is part of the
project deployment, and changes there must be tracked. If your project
requires a 'logs' directory, then a logs directory must be a versioned
resource that you can check out at any point in it's past.

Just as importantly, any changes that you make in the project
structure in development must be replicated to the production
deployments, and therefore must be tracked.


3) Django apps are also python libraries.

A 'django app', regardless of what it does, is also a python library.
Therefore, make sure you give it a setup.py script using distutils
that will allow you to do standard python library packaging operations
on it. Pip will happily install an app from source control, it will
even install in a manner that allows you to edit and commit changes
back to source control.
This allows you to install packages in development in the same way as
production.


4) Write a bootstrap script.

A bootstrap script is a simple shell script that does two things -
sets up a virtualenv environment, and installs a set of packages.
This combination of storing project structure in source control, using
virtualenv and pip, having a bootstrap script and having a
requirements.txt listing your required packages allows you to simply
checkout a project and run it's bootstrap script to end up with an
identical, repeatable project environment.


6) Use the capabilities of your source control to assemble a deployment

This is the tricky one where I tend to lose people! We use subversion
for source control. Subversion allows us to specify 'externals', which
are secondary subversion repositories that we want to be automatically
checked out in specific locations within another repository. You can
also have 'file externals', which is a single file (rather than an
entire repository tree) that is checked out at a specific location.

The benefit of this is that you can use your project structure
repository as a basis for a deployment on a single site, by
duplicating it for each server that you wish to deploy on.
On each one, you would have an external adding the project source code
in the right place. You would have a file external that pulls in a
'requirements.txt' file correct for this project into the right place.
You would have another file external that pulls in the correct
settings.py (or settings_local.py if that is what you prefer).


7) Use South

Use south for database mi

Re: CSRF in javascript

2013-07-20 Thread Fred Stluka


Karl,

Since you already have a form, and are already submitting it
as an Ajax request via JavaScript, the easiest way is to just
put the {% csrf_token %} in the Django template for the page.
We do that for our Ajax forms.

If you are not using a Django template to generate the form,
there are lots of other convenient options.  See:
- https://docs.djangoproject.com/en/dev/ref/contrib/csrf/
and especially:
- https://docs.djangoproject.com/en/dev/ref/contrib/csrf/#ajax

Also, you can find tons of working examples by Googling:

*Subject: *implement gmail type address adding functionality in django

I want to implement the functionality available for adding email
address in gmail in my application.

In gmail,in compose mail if we type the 1st character of the email
address,it will show the list of suggested email address.The same
concept,i want to implement in django for contact name.The list of
names are saved in database,so typing any letter of the name,it
should show the list of suggested names and from that user can
select the name.

I need some post or blog to get an idea to do this.


Cheers!

Roopa

Re: Why is RequestContext used in this way?

2013-11-15 Thread Fred Stluka

Andy,

RequestContext is being passed in so that it become available
to the template, so that it can do things like {% csrf_token %}
which requires access to the session id.

I'm not sure what would happen if a dictionary were passed to
RequestContext as an optional 2nd argument. I've always
passed the dictionary directly to render_to_response().

Hi,

I've followed some example code which is is follows:

def index(request):
context = RequestContext(request)
context_dict = {'boldmessage': "I am from the context"}
return render_to_response('rango/index.html',context_dict, context)

Here RequestContext only has the first argument filled i.e. request.

My questions are:

1. Is RequestContext(request) being used in a kind of dummy way to
suck up the context processors for render_to_response?
2. What would render_to_response be doing if has both context_dict AND
RequestContext had a second argument?

Sorry if these are stupid questions. I'm new to everything python and
Dango, and the kind of person who forgets everything they have ever

Re: mod_wsgi setup

2013-11-15 Thread Fred Stluka


tino,

I have a working setup, using Apache mod_wsgi on AWS Linux.

Try adding the location of your virtual env to to your Apache settings.
Something like:

==

WSGIPythonHome /var/python27/virtualenvs/hhl

==

If that doesn't help, here are some more thoughts.

My django.wsgi file looks similar to yours.  Differences in red:

==

import os, sys
sys.path.append('/var/www/django/hhlweb')
sys.path.append('/var/www/django/hhlweb/hhl')
sys.path.append('/var/python27/virtualenvs/hhl/lib/python2.7/site-packages/django/db/backends')
os.environ['DJANGO_SETTINGS_MODULE'] = 'hhl.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

==

What does your wsgi.py file look like?  Mine is:

==

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "hhl.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

==

I found these links useful when I set mine up last year:

Re: Downloading thumbnails and replacing them with full images

2015-01-24 Thread Fred Stluka


+1 for easy-thumbnails.  We use it and it works great.  Allows
the user to upload images, optionally crop them during the
upload, manages the full-size and thumbnail files on the file
system with their names in the DB, etc.  All automatic and all
easy.

something like this and knew of any packages or can give any hints or
advice.


My suggestion - look into easy-thumbnails:

http://easy-thumbnails.readthedocs.org/en/latest/index.html

It's an augmentation of Django's ImageField that allows you to store a
"single" image in your model, but also specify policies for how thumbnails
of any image will be generated (in multiple sizes, if needed). The field
will then automatically generate those thumbnails (either on upload, on
demand on download, or in a background process, depending on how you
configure it), and provide an easy way to find the media URL for each
thumbnail (as well as the original).

Thanks very much for the reply Russell. Before I got your message I
found SuperBox which seems to be working for me. But I will keep
easy-thumbnails in mind for the future.

I mean, you have basic knowledge of how Django works, what was your
further steps towards becoming Django expert?

That's easy. Build something which will be useful to you. You have two choices:

1. Find an existing Django app and install it and use it. Change it to suit 
your own needs https://www.djangopackages.com/

2. Start from scratch and build it from the ground up.

I prefer #1 but I actually did #2 and essentially relied on the excellent 
Django Admin. Your mileage might vary.

In both cases you need to become familiar with the Django docs because when you 
try something you need to know what you are doing and the docs are the best 
resource. They are great.

Good luck

Mike


I'm asking that because I'm curious what actions people did to become
Django experts, and perhaps I and other beginners can learn something
from it.

Error importing dbapi2...

2014-08-25 Thread Fred Stluka


I'm getting error:

django.core.exceptions.ImproperlyConfigured:
Error loading either pysqlite2 or sqlite3 modules
(tried in that order): cannot import name dbapi2

Any suggestions?

Details:

My settings.py contains:
DATABASE = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': '/Users/fred/fred/HHL/HHLWeb/sqlite3.db'
}
}

Works fine with other DBs (MySQL, MS SQL Server, etc.), but now
I'm trying to switch to SQLite for faster testing.

From the command line, I can see that sqlite3 is installed
(by default as part of the Django install), but seems to not
contain dbapi2:

>>> import sqlite3
>>> from sqlite3 import dbapi2
Traceback (most recent call last):
  File "", line 1, in 
ImportError: cannot import name dbapi2

Any ideas for me?  Any suggestions on how to narrow down
the problem?  Any more info I should give you?

Thanks!

How quickly do Django unit tests run?...

How quickly do Django unit tests run?

Mine are taking 7-9 seconds each, even for trivial tests like:

Is this typical?  Or do I have something misconfigured.

Re: How quickly do Django unit tests run?...

2014-08-27 Thread Fred Stluka


Ben,

Thanks!  That's exactly the kind of ballpark figure I wanted.

Sounds like I should be expecting roughly 5-10 tests/sec, plus
maybe 10-20 secs DB setup/migration.  I'm currently seeing 1
test per 7-9 secs, plus 50-60 secs DB setup time (syncdb, not
South, since I'm setting SOUTH_TESTS_MIGRATE = False).

Yeah, something must be wrong here.  I'm running 100X slower
than expected.

BTW, are those numbers using SQLite, MySQL, PostgreSQL, other?
So far, I'm using MySQL, running locally on a pretty fast Mac laptop.
I'm planning to switch to SQLite for testing, to make it run faster,
but haven't gotten that to work yet.

My next steps will be try again with SQLite, and perhaps get the
test suite to run in the PyCharm debugger so I can step through
the code and see where all the time is going.

Thanks again!

Re: Error importing dbapi2 (SOLVED)...

2014-08-29 Thread Fred Stluka


I figured it out.

Details:

I had set environment variable PYTHONPATH to help Django
find the sql_server.pyodbc files needed to make a connection
to a Microsoft SQL Server DB.  This was keeping SQLite from
working properly.  When I cleared the environment variable,
SQLite works fine.

I now get no errors when I do:
>>> import sqlite3
>>> from sqlite3 import dbapi2

and I no longer get the error about dbapi2 when I run my
regression tests via Django.

To get the sql_server.pyodbc file to be found, I now use a
symlink:
% ln -s django/db/backends/sql_server \
~/python/virtualenvs/hhl/lib/python2.7/site-packages/sql_server
instead of setting PYTHONPATH:
% setenv PYTHONPATH 
~/python/virtualenvs/hhl/lib/python2.7/site-packages/django/db/backends

Re: How quickly do Django unit tests run?...

2014-09-02 Thread Fred Stluka


Benjamin,

Thanks for the followup!

I've been using MySQL.  For normal (non-testing) use, it seems
fast enough on our development machines (Mac laptop) and in
our TEST and PROD environments (Linux on AWS).  Page loads
are typically sub-second.  It was only when I used the command:
% python manage.py test
that I saw the long delays.

I assume the delays are related to the default stuff happening in
setUp() and tearDown() for each test.  Still happens with SQLite,
I assume.  Just much faster.  I may step through in the debugger
sometime to confirm this.

I read the slides at the URL you gave me.  Good info!  For now,
our site is fast enough and is not expected to scale dramatically,
but we do have a JIRA ticket for improving performance if/when
we need it.  So far, I've tossed a bunch of idea in there, but not
needed to do any of them:  profiling, caching, file minimization
and packaging, tuning mix of Ajax vs full page loads, etc.
I've added this URL to the JIRA ticket for further consideration
if/when we need it.

Is there a more current version of the slides?  This copy was
presented to OSCON in 2011, and refers to Django 1.3 as new.

Here are some notes I added to our JIRA ticket along with this
URL for if/when we need it:

- Beware ManyToManyField
- Beware over-indexing
- Look into pg_stat_activity (PostgreSQL), or MySQL equivalent
- Prefer NULL to DEFAULT when migrating a large table
   - Or do it 3 steps shown to avoid long lock on DB table
- Consider direct SQL sometimes instead of Django ORM
- Beware iterating over large querysets
- Beware filters with "__in" that match more than 10-15 items
- Beware OFFSET
- Use replication or a backup DB copy for large reporting operations
- Don't use DB as Celery job queue
- Use @commit_on_success or TransactionMiddleware
- Leave autocommit on (even thought it seems wrong)
- Modify tables in a fixed order.  Same for rows of a table.
- Pass QuerySets directly to templates (to allow lazy evaluation)
- Cache templates and fragments
- Cache expensive query results
- Pool DB connections if over 100 concurrent users
- Use db_routers.py to write primary DB, read replica DB

Thanks again!

What DB were you testing on before? Unless you're going to launch this 
thing into production with SQLite I would recommend you switch back to 
whatever DB you're planning for production and test with it as you 
probably have some serious performance considerations to work out 
asap. If they're architectural rather than configuration-based issues 
then the sooner you recognize and repair them the better. If you 
happen to be using Postgres out of the box with no changes from your 
distro's base install then it's going to be real slow because 
Postgres' default config is to use as few resources as possible which 
necessarily makes performance less than optimal. It's not hard to make 
Postgres a very fast DB but you better start using it right to make 
things go well when you launch.


See this article for some good advice: 
http://thebuild.com/presentations/unbreaking-django.pdf It's a bit 
dated and newer versions of Django improve on the old implementation 
of the ORM but it's recommendations and things to look out for are 
sound. You need to measure your actual performance and act accordingly.


Good luck,

Hi Michael,

There's nothing built into Django 1.7, or any previous version;
however, it's also not hard to implement yourself. All you have to do
is override the save method on your model, and in that method, and
store whatever audit information you want to record. So, for example,
if you want to just keep a track of the person who most recently
edited a record, you could do something like:

class MyModel(models.Model):
author = models.ForeignKey(settings.AUTH_USER_MODEL)
... (other fields here)

def save(self, user, *args, **kwargs):
return super(MyModel, self).save(*args, **kwargs)

Then, every time you save an instance of MyModel, you need to pass in
the user who saved the record; e.g.:

MyModel.objects.save(request.user)

If you want to record a full audit record of every edit, you could do
that too; you just create a secondary model type, and every time you
save your base model, you create an instance of the secondary type as
well.

If you don't want to roll it yourself (or your use case is fairly
generic), you might find some pre-rolled django apps that can help:

https://www.djangopackages.com/grids/g/versioning/

I can't speak from experience on any of them, but they exist, and you
might find that one of them meets your needs.

Yours,

I do this via the jQueryUI "dialog" widget.  Works fine with Django

dialog box or simply a division instead of that window.

Using window.open method, clicking on the "Advance", "popitup"
function runs. Here's the code:
http://pastie.org/9580729

The popitup function takes the passed url and opens a window
containing template sent by the view. But how to open a dialog box
instead?

I've tried using AJAX, like told in the link below but yet unable to do:

Re: Is there anything similar to phpmyadmin

2014-09-22 Thread Fred Stluka


There's some really nice DB admin functionality in PyCharm.

It's not open source, or even free, and it's not written in Python,
but it's part of an IDE that I use (and many others here?) for
developing our Python/Django code.

Hope this helps!

Re: Upgrading Django (to 1.7)

2014-09-25 Thread Fred Stluka

Sabine,

I'm not sure about the new 1.7 Migrations, but with South,
restarting your migrations is easy.

I'm currently doing it on my project, because we have a
long convoluted history of changes before and after we
started using South, and have made some mistakes along
the way (like editing migrations and fixtures that they use
after running them -- bad idea!). Since we're at a nice
stable point now, and are certain we'll never need to
migrate back to an earlier version, I'm currently deleting
all the old migrations and creating new clean ones that get
us to our current state.

Steps:

- Delete all rows from south_migrationhistory table.

- For each app
- Delete old migration files from migrations folders
- Run: python manage.py convert_to_south /appname/
to create and fake the 0001_initial.py migration.
This creates a file in the migrations folder and adds
row to the south_migrationhistory claiming that the
migration has already been run.

- For each app with models mapped to DB tables that
contain data you would want to pre-load into a newly
created DB (lookup values like countries, states,
statuses, etc.):
- Run: python manage.py datamigration /appname/ /migration_name/
to create a new migration named 0002_/migration_name/.py
with empty forwards() and backwards() methods.

- For each such DB table:
- Run: python manage.py dumpdata --indent=4 /appname.ModelName/ >
.//appname//fixtures//table_name/.default.json

- Add to forwards() method:
call_command("loaddata", "/table_name/")

Dear Andrew,

I read your article and it is great. I am really looking forward to
your followups. I was hoping for something like this went I attended
Django Con Europe. I struggle with the understanding the migrations
the most. Usually in the early phases of development I do not want
migrations to bother me since my database design just still changes
too often for keeping track. I find the django admin a very useful
tool to test your database design with real data and detect flaws
early on. So will your followups contain advise on that? How can I
restart migrations all over once my project is ready for deployment?

Thanks so much for writing these very useful articles! Do you mind if
I post about them in the Django user facebook user group, or do you
want to do that, since I think these articles will be very helpful to
most Django developers.

with kind regards and keep going!

You can control the order in which migrations run.

For South, see "depends_on" and "needed_by":

For Django 1.7 migrations, see "dependencies":

Andrew, thanks for the article, and the more-to-come.

When you get to data migrations, you might want to cover a problem I
ran into with them: when I had a data migration in the middle of a
sequence of other migrations, and then later wanted to set up a new
environment, which meant running all of the migrations in sequence
from the beginning, the data migration was now running in the latest
models.py code, not the code in which it initially worked. So it did
not work any more.

In particular, the data migration was a precursor to another schema
migration were a field would be removed. The data migration was to
move the existing data in the field-to-be-removed to a different
field. So when the data migration ran in the longer sequence, the
field it was trying to move data from was now gone from the code.

I suspect there are a lot of other ways to shoot yourself in the foot
with data migrations, so we have stopped using them and just use our
own data migration scripts outside of the sequence of schema migrations.

Fwd: Re: Upgrading Django (to 1.7)

2014-09-27 Thread Fred Stluka


Bob,

Are you referring directly to the models by name in the data
migrations?  That could be the problem, because yes, the migration
would be using the latest models at the time that the migration is
executed, not the models as they stood at the time that the
migration was written.

There's a warning in a comment in the boilerplate code generated
for each data migration by the command:
% manage datamigration  

It says:

def forwards(self, orm):
"Write your forwards methods here."
# Note: Don't use "from appname.models import ModelName".
# Use orm.ModelName to refer to models in this application,
# and orm['appname.ModelName'] for models in other applications.

and there is a dictionary of the models as they existed at that
time shown later in the same file.

If you always follow this advice and manipulate orm.ModelName
instead of appname.models.ModelName, it should solve exactly
the problem you are describing.

Hope this helps,

This was awhile ago, and my memory might be faulty. Do the latest 
migrations give you any way to deal with that situation? I mean, do 
they migrate the models in models.py in sync with the the database 
schema migrations?


I can see where a data migration might work in a schema migration 
sequence if you expressed it all in SQL, just dealing with the 
database alone, but we of course wrote in Python using the Django ORM.

interact badly with initial_data fixtures.  OK to use fixtures, but
load them explicitly via "loaddata" from data migrations. Don't
put them in "initial_data" fixtures.

Also, good explanations of:
- South in general
- The reason why there's a models dictionary (the "frozen model")
   in each migration file, and why to use orm.ModelName
- Differences from Django 1.7 migrations
- How to get started with Django 1.7 migrations
- Unicode vs ASCII issues
- Use of objects.bulk_create()

Thanks!

Andrew,

Excellent 3rd article.  Thanks again!

I've recommended it to my team, summarizing it as:
- South vs Django 1.7 Native Migrations
- Upgrading from South to Django 1.7 Native Migrations
- New "App Registry"
- New "System Check Framework"
  -- Invoke via: % python manage.py check
  -- Also runs implicitly as part of most manage.py commands.
  -- Has hooks to add your own checks to enforce project standards, like:
 --- All Models must have a __str__ method.
- New "Custom Querysets"
  -- Often better than writing a custom manager
- Improved prefetch_related()
- New "Custom Lookups"
- Improved form error handling


The App Registry section is not entirely clear to me, probably
because I'm coming from 1.4, not from 1.6.

It might help if you explained how the App Registry relates to
1.4 concepts.  Like, I assume it replaces INSTALLED_APPS, plus
a whole lot more, right?

Otherwise, can you suggest where I can find an article similar to
yours that gets me from 1.4 to 1.5 and on to 1.6 before I use
yours to get me from 1.6 to 1.7?

Thanks!

Andrew,

Yes, that explains a lot.  I'd recommend including this explanation
in one of the articles of your current series.

BTW, one other thing to keep in mind is that we 1.4 users don't
know what an apps.py file is, so we don't appreciate not having
to create one, since we never did before.

Thanks again!

Hi Fred,
Thanks again for the positive feedback!

I'm sorry I lost you at the App Registry section. I'm afraid I can't recommend 
an article to help with the topic, either. Given your questions, I can see I 
missed the mark. Let me give it another go (warning: this is neither 
technically reviewed nor copy edited).

Django uses the `INSTALLED_APPS` setting to find all of the apps in a project, 
and to build a list of apps to run and use, called an app registry. The way 
Django builds the app registry has changed radically from Django 1.6 to Django 
1.7.

Django 1.6 (and before, but I admit I don't know how far back) used the 
`AppCache` class to maintain a list of these apps. The system was problematic 
because each `AppCache` instance shared state - any change to one `AppCache` 
object lead to a change in all `AppCache` objects. Because of migrations (and 
the need for historical/frozen models), the `AppCache` had to change in Django 
1.7.

Django 1.7 now provides an `Apps` class to be the app registry. Each instance 
is separate from others, allowing the migration system to build historical apps 
and models. You can fetch the `Apps` object (not class!) for your own project 
with:

 from django.apps import apps as django_apps

Referred to as the master registry (the app registry for your project as it 
runs), `django_apps` is an instance of `Apps`, which contains a list of 
`AppConfig` objects.

Starting in Django 1.7 all apps now have an `AppConfig` object attached to 
them. These are built automatically by Django, meaning many developers will be 
able to get away without ever creating an `/app_name/apps.py` file for their 
projects. The ability to override `AppConfig`, however, is quite useful. It 
allows for the implementation of a `ready()` method (seen in the admin 
`AppConfig` subclass) as well as the ability to explicitly set the app label, 
allowing developers to easily rectify namespace conflicts.

Note that we avoid a namespace error thanks to `as django_apps` with 
`AppConfig`. I recommend you do this even if there is no namespace error.

 from django.apps import apps as django_apps
 from . import apps

To deal with this list of `AppConfig` objects (and the models within), all 
`Apps` instances sport a brand new API. We saw it throughout Part II and Part 
III of the article, using it to help us with data migrations and to build our 
checks.

The only trick with `Apps` is that it must be fully built and configured before 
Django can take certain actions, including loading the custom user model, or 
using parts of the translation system. I touched a little bit on it in Part 
III, but plan to expand on it in Part IV.

The bottom line is that the app registry works mostly in the background by 
building a master registry and performing many of its key functions without 
developers ever knowing (just as many developers never knew about Django 1.6's 
`AppCache`). However, understanding the system even a little allows for the 
developer to better edit migrations and create checks, and I suspect that 
interacting with apps via this API will become commonplace.

Fred: Is the above helpful? Feel free to ask more questions.

No, but I hope the process I lay out in Part IV will help you indirectly.

Re: Loading fixtures in Django 1.7

Leonard,

In Django 1.4, you would add this code to the forwards()
method of the migration:

from django.core.management import call_command
call_command("loaddata", "")

I am in the process of upgrading from

I have three fixtures.  I am trying to figure
out how I should load them.

One fixture is `initial_data.json`, and I know
that starting with Django 1.7 this special
fixture no longer gets automatically loaded
as it did when we used to run `syncdb` (i.e.,
prior to deprecation in Django 1.7).

So I know all three fixtures should be loaded
the same way as each other, whatever way that
may be.

My main question is:

Should I keep using `loaddata`, as in:

python manage.py loaddata .json

Reading the documentation I get the sense
(though I am not sure) that now the preferred
approach to load fixtures is to create a
migration to perform the loading.  But I
don't see an example of how to do this
process from beginning to end.  It looks
like the process starts with creating an
empty migration, then manually editing the
migration file to define a function like:

def load_data(apps, schema_editor):

But I don't know how to write this function
(`load_data`), and I can't find an example.

Re: how to test an application that's using a legacy database

2014-11-10 Thread Fred Stluka


David,

No.  You can use it unchanged.  With Django 1.4 at least, and I
assume also with 1.7.

I have a legacy MS SQL Server DB where I have rights to modify
data but not tables.  I also cannot create new DBs in MS SQL
Server.

I used *inspectdb* to create models from the existing DB.

I generally have them marked as *managed=False*, but when
running tests, I have them *managed=True*, and I override the
*DATABASES* settings to point to SQLite, instead of MS SQL Server.
Thus, when I run the tests, the test DB is created in SQLite, and
the real DB server is untouched.

Here's how I do it:

*settings.py:*

DATABASES = { ... the usual stuff ... }

# Decide whether we're running unit tests
RUNNING_UNIT_TESTS = 'test' in sys.argv

if RUNNING_UNIT_TESTS:
DATABASES['default'] = { 'ENGINE': 'django.db.backends.sqlite3', }

*models.py:*

class Meta:
managed = True if settings.RUNNING_UNIT_TESTS else False

Hi,
I'm writing a Django application that uses an existing database. If I 
understood it well, in such a case one must create non-managed models 
for the legacy tables to avoid Django creating already existing 
tables, right?

For instance, this is how one of my models looks like:

|
classJobInfo(models.Model):
job_db_inx =models.IntegerField(primary_key=True)
id_job =models.IntegerField()
id_user =models.IntegerField()
id_group =models.IntegerField()
account =models.TextField(blank=True)
cpus_req =models.IntegerField()
cpus_alloc =models.IntegerField()
nodelist =models.TextField()
nodes_alloc =models.IntegerField()
partition =models.TextField()
time_start =models.IntegerField()
time_end =models.IntegerField()
was_updated =models.IntegerField()
jobmondatacleared 
=models.IntegerField(db_column='jobMonDataCleared')# Field name made 
lowercase.
endupcount =models.IntegerField(db_column='endUpCount')# Field 
name made lowercase.

approved =models.IntegerField()

classMeta:
managed =False
db_table ='job_info'
|

The problem, of course happens when the unit tests are run. The test 
database must be created when the tests start. But because "managed = 
False", the tables are not created.


First round.
Googling a bit I found a recipe to by-pass this problem: modify the 
DiscoverRunner class (I found it in here 
<http://www.caktusgroup.com/blog/2010/09/24/simplifying-the-testing-of-unmanaged-database-models-in-django/>, 
and tailor it trvially to remove the deprecation warning):


|
classManagedModelDiscoverRunner(DiscoverRunner):
defsetup_test_environment(self,*args,**kwargs):
fromdjango.db.models.loading importget_models
self.unmanaged_models =[m form inget_models()
ifnotm._meta.managed]
form inself.unmanaged_models:
m._meta.managed =True
print("setting %s._meta.managed to True"%(m.__name__,))
super(ManagedModelDiscoverRunner,self).setup_test_environment(*args,**kwargs)

defteardown_test_environment(self,*args,**kwargs):
super(ManagedModelDiscoverRunner,self).teardown_test_environment(*args,**kwargs)
# reset unmanaged models
form inself.unmanaged_models:
m._meta.managed =False

|

So I created a directory in my project called "tests" and put the 
above code in a file called "managed_runner.py" in there. To be more 
explicit, the tree looks like:


|
|--myapp
||--admin.py
||--__init__.py
||--models.py
||--templates
||`-- myapp
|   |   `--home.html
||--tests.py
|`-- views.py
|-- myproj
|   |-- __init__.py
|   |-- settings.py
|   |-- urls.py
|   `--wsgi.py
|--manage.py
`-- tests
|-- __init__.py
`--managed_runner.py

|

Then I modified my "settings.py" file adding

|
TEST_RUNNER="tests.managed_runner.ManagedModelDiscoverRunner"
|

to it. And I ran the tests. Still, it fails:

|
django.db.utils.ProgrammingError:Table'test_db.job_info'doesn't exist
|

But I see the output of print in the screen saying that the models' 
._meta.managed attributes are set to True.



Second round.
Reading the Django docs, I see that DiscoverRunner has a couple of 
interesting methods: setup_databases and teardown_databases. I tried 
to subclass the DiscoverRunner again, this time it looks like:


|
classManagedModelDiscoverRunner(DiscoverRunner):
defsetup_databases(self,**kwargs):
fromdjango.db.models.loading importget_models
self.unmanaged_models =[m form inget_models()ifnotm._meta.managed]
form inself.unmanaged_models:
m._me

Re: Deploying Django project

2014-11-20 Thread Fred Stluka

termopro,

I have automated my deployments mostly separate from my
version control.

The other team members and I write, test, commit, and push our
code changes to our Git repo. I then pull, review, test, update
the version number, commit, tag, and push to Git.

Then I use a shell script (on Mac, but would work on Unix/Linux
also) to push the tagged commit to TEST and later to PROD.

My script does things like:

- Get the latest files from Git before, and back to master after:
% git checkout mytag
...
% git checkout master

- Create folder of collected static files before, and delete after:
% mkdir -pv collected_static/mytag
% python manage.py collectstatic --clear --noinput
...
% rm -rfv collected_static

- Delete all local *.pyc files:
% find . -name \*.pyc -exec rm -v "{}" ";"

- Insert PROD password into local settings file (PROD pushes
only) before, and remove after:
% sed -i .old -e "s/PUT_PROD_PASSWORD_HERE/`cat prod_pw`/g" settings.py
...
% mv -v settings.py.old settings.py

- Show a warning banner at the Web site to say it is going down
briefly, and clear the banner after:
% ssh -t myserver.mydomain.com cp -v
/var/www/django/myapp/templates/myapp/site_alert_maintenance.html
site_alert.html

% sleep 60
...
% ssh -t myserver.mydomain.com cp -v
/var/www/django/myapp/templates/myapp/site_alert_none.html site_alert.html

- Push the local files to the TEST or PROD server:
% rsync -v --progress -i -l --rsh=ssh -r --del myapp
myserver.mydomain.com:/var/www/django

- Run all migrations on the server
% ssh -t myserver.mydomain.com python manage.py migrate --all

- Stop the Apache server, delete all remote *.pyc files, and
restart the server:
% ssh -t myserver.mydomain.com sudo /etc/init.d/httpd stop
% ssh -t myserver.mydomain.com sudo find /var/www/django/myapp -name
\*.pyc -exec rm -v "{}" ";"

% ssh -t myserver.mydomain.com sudo /etc/init.d/httpd start

Plus a few other actions that are specific to our app, and lots
or informational messages, prompts, confirmations, etc. Also,
some of these steps are combined into a remote script that
runs on the server to reduce the number of "ssh -t sudo"
commands I would otherwise have to do. But, that's the gist
of it.

Hope this helps!

2) Upload code/ database changes to remote machine:

Most tutorials/articles about deployment do not cover 1.c and 2.b.
Also the tasks 1.b. and 2.a. are solved using revision control tools

So i'd like to know:

1) How do i install Django project or it's updates without

2) How do i automate the task of uploading required database

Re: Advice needed: Adaptive/Responsive Images in Django?

2014-11-20 Thread Fred Stluka

Right. Very good article.

The gist is to use the new HTML5 "" and ""
elements along with the "sizes" and "srcset" attributes of
"", and perhaps the CSS3 "calc()" function to specify
multiple sizes of the same image, so the browser only
downloads the right one for the current screen size, all in
a way that falls back to slower but acceptable for older
browsers.

BTW, if you're willing to throw a little JavaScript into the mix,
and not limit yourself to just CSS, you can do truly amazing
things with RWD (Responsive Web Design). I've been doing
it for about 14 years. See, for example:
- http://bristle.com/RWD/BrightPanelsDemo/
Drag the window wider and narrower and watch the panels
completely re-configure themselves, nesting/un-nesting,
stacking/un-stacking, hiding/showing, etc. Anything is
possible.

do you have a tip for implementing adaptive (responsive) images in

Basically I want to server smaller images to mobile-users and

I don't really now about best practices for SEO and

Are there any apps that you can recon for this?

Git is you friend here. You can create a private repo in your prod

termopro,

I have automated my deployments mostly separate from my
version control.

The other team members and I write, test, commit, and push our
code changes to our Git repo.  I then pull, review, test, update
the version number, commit, tag, and push to Git.

Then I use a shell script (on Mac, but would work on Unix/Linux
also) to push the tagged commit to TEST and later to PROD.

My script does things like:

- Get the latest files from Git before, and back to master after:
   % git checkout mytag
   ...
   % git checkout master

- Create folder of collected static files before, and delete after:
   % mkdir -pv collected_static/mytag
   % python manage.py collectstatic --clear --noinput
   ...
   % rm -rfv collected_static

- Delete all local *.pyc files:
   % find . -name \*.pyc -exec rm -v "{}" ";"

- Insert PROD password into local settings file (PROD pushes
   only) before, and remove after:
   % sed -i .old -e "s/PUT_PROD_PASSWORD_HERE/`cat prod_pw`/g"
settings.py
   ...
   % mv -v settings.py.old settings.py

- Show a warning banner at the Web site to say it is going down
   briefly, and clear the banner after:
   % ssh -t myserver.mydomain.com <http://myserver.mydomain.com>
cp -v
/var/www/django/myapp/templates/myapp/site_alert_maintenance.html
site_alert.html
   % sleep 60
   ...
   % ssh -t myserver.mydomain.com <http://myserver.mydomain.com>
cp -v /var/www/django/myapp/templates/myapp/site_alert_none.html
site_alert.html

- Push the local files to the TEST or PROD server:
   %  rsync -v --progress -i -l --rsh=ssh -r --del myapp
myserver.mydomain.com:/var/www/django

- Run all migrations on the server
   % ssh -t myserver.mydomain.com <http://myserver.mydomain.com>
python manage.py migrate --all

- Stop the Apache server, delete all remote *.pyc files, and
   restart the server:
   % ssh -t myserver.mydomain.com <http://myserver.mydomain.com>
sudo /etc/init.d/httpd stop
   % ssh -t myserver.mydomain.com <http://myserver.mydomain.com>
sudo find /var/www/django/myapp -name \*.pyc -exec rm -v "{}" ";"
   % ssh -t myserver.mydomain.com <http://myserver.mydomain.com>
sudo /etc/init.d/httpd start

Plus a few other actions that are specific to our app, and lots
or informational messages, prompts, confirmations, etc. Also,
some of these steps are combined into a remote script that
runs on the server to reduce the number of "ssh -t sudo"
commands I would otherwise have to do.  But, that's the gist
of it.

    Hope this helps!

Re: Web and mobile app with Django? Kivy? sth else?

2014-11-24 Thread Fred Stluka

+1 for writing a single RWD (Responsive Web Design) web app
using Django, instead of writing separate web, Android and iOS
apps.

If necessary, wrap the result in PhoneGap to mobile-specific
features, uploading images from the camera, capturing the
GPS location, showing maps, accessing the local file system
and contacts, etc. But only if you need those features.

My current project uses RWD techniques to look good on
phones, tablets, and full screens. Lots of jQuery, Ajax, HTML5
and CSS3 for a rich user experience. Drag any of the pages
wider or narrower to see what I mean:

Hi,

Django can do all of those things except the native android/ios apps.
Django specializes in websites and especially helpful for handling
things like logging in, querying a database, processing form input,
and generating html.

Here are some ways Django can help with your situation:
You could build native android/ios apps and use Django for the server
side of your app, like how Instagram does it. You could handle the
desktop side as a website made with Django. If you really wanted
low-cost-maintenance, you could have your android and ios apps just be
simple wrappers around a webview that's loading content from Django.

Re: Image input missing from POST request

2014-11-26 Thread Fred Stluka

Abhishek,

Good tip about the syntax! I didn't realize
you could do that to avoid having to nest the fields
inside the .

I just looked it up at:
- http://www.w3schools.com/tags/att_input_form.asp
where it says 2 interesting things:
- Not supported in IE
- Can specify multiple forms that the same input field is
a part of, so presumably, the field would be POSTed with
any of the listed forms. Rest of the page does not make
it obvious how to do that though. Value is a string of
space-separated form ids perhaps?

Any comment of either of these 2? Have you tried your app
on IE? Have you tried specifying multiple forms?

Thanks!

Hi Collin,

Thanks for taking time out to look at this. It turns out that I
somehow I copied the rendered HTML wrong! The real problem was that
the form id used in input was incorrect and this was the reason for

Separately, this is not really a trick but a fairly standard technique
nowadays, and after correcting my mistake, it works just fine.

The input field is outside the closing tag so

just my links page.  Use:  http://bristle.com

I'm re-posting my privately emailed comments on the latest

Looks good!

You did a great job of explaining the bits that I previously
didn't get:
- Relationship of INSTALLED_APPS to App Registry
- History of the App Registry
- AppCache, Apps, AppConfig
- apps.py
- Custom AppConfig

Also:
- app registry vs. master registry
- label vs. name in AppConfig
- Need for renamed imports
- Exact sed command to change an app's label
- AppConfig.ready()
- autodiscover()
- Apps restrictions (custom user model)

The Check Framework section is now also very clear, and it
seems to be very complete as well.  I like the iterative
approach you use: describing a simple way, then a problem,
then an enhancement that solves the problem, then another
problem, etc.  Nice job!  This will be very useful when I start
using the Check Framework to enforce coding standards for
my team when we move to Django 1.7 or 1.8.

Lots of good advice on how to upgrade, including:

- Value of having a test suite
- Use of DEV/TEST/PROD and virtualenv
- Importance of going to 1.5, then 1.6, then 1.7, as separate

- Upgrading Python itself
- Release notes for each version

Also, for anyone local to Philadelphia PA, I expect to be
recruiting onto my own team in about a month or so.
Telecommute with weekly status meetings in Radnor PA,
and ad-hoc local co-working sessions with the dev team.

Interested in either one, please let me know.

the right guy can get them to double the salary to get it up to
market rate.  So it would be selfish of me to not at least tell
you about it.

Fred,

Thank you for your detailed response and good luck with your project.

I'll attempt to answer your questions and anyone interested can
contact me for more details -- thanks!

Some questions I always ask (some of which were answered
in your attached job description):
- Brief description of the company, what it does, what the
   work environment is like, etc?

Educational software product company, start-up, college portal
product that was successful at one college and rolling it out
across the country.

- Brief description of the responsibilities of the position you
   are trying to fill?

See JD, mid-senior level, some mentoring/coaching of junior
developers

- Technologies used and skills needed?

See JD

- Consultant or FTE?

Consultant at first under my firm, then fulltime with my client

- Full time or part time?

Fulltime

- How long is the initial contract?

6-month contract to hire, more or less based on client preference

- How long is the project likely to run?

Fulltime position after contract

- Approx salary or hourly rate offered?

Salary in the $80-100K for fulltime, some leeway higher if needed,
salary converted to hourly for contract period

- Location (Philly, western suburbs, Wilmington, telecommute, etc.)?

Telecommuting, client is located in Indy, occasional travel to
Indy required but should not exceed 1-2 weeks annually, 1-2 weeks
onsite at start of contract to meet team/etc.



Wow!  That is a REALLY good match for my skills and interests!

I particularly like these aspects (almost everything you described

- Telecommute
- Demonstrative excellence
- Participation in the open source community
- Provides expert knowledge and guides best practice
- Fanatically documents all code via docstrings and Sphinx
- Increases test coverage via Test Driven Development
- Writes unit tests

## Install pyodbc for Mac

2014-07-16 - Fred and Jim found new information for Max OS X

from: 
http://stackoverflow.com/questions/20074620/installing-pyodbc-fails-on-osx-10-9-mavericks

OSX Mavericks dropped sql headers that are required for pyodbc compilation.

Following these steps allowed me to install pyodbc:

1. Install the iODBC library  (http://www.iodbc.org/)
1. Download tar file from website, libiodbc-3.52.9.tar
2. Extract iODBC sources from the tar file.  We extracted into 
directory

   /Users/jim/Downloads/libiodbc-3.52.9
2. Run pip install --allow-external pyodbc --allow-unverified pyodbc 
--no-install pyodbc

3. cd [VIRTUAL_ENV]/build/pyodbc
4. Run  python setup.py build_ext 
--include-dirs=/Users/jim/Downloads/libiodbc-3.52.9/include/

5. Run pip install --no-download pyodbc

 Mac OS X note

The `pyodbc` package that _pip_ installs uses iODBC by default. We want it
to use `unixODBC`, instead, for a couple reasons.

* First, there are numerous sites on the Internet that make claims such as
  "iODBC is a slightly less desirable ODBC manager than unixODBC"
(http://www.cerebralmastication.com/2013/01/installing-debugging-odbc-on-mac-os-x/).
  More people _seem_ to have better luck with `unixODBC`.
* Second, we're using `unixODBC` on Linux, and the configuration is already
  complicated enough. So, why not just use the same approach on both 
platforms?

To get `pyodbc` to use `unixODBC` on the mac, you have to build it from 
source,

and you have to hack the `setup.py`. Here's how to do it.

$ . ~/pythons/hhl/bin/activate
$ cd /tmp
$ git clone https://code.google.com/p/pyodbc
$ cd pyodbc
$ patch >> import pyodbc
>>> conn = pyodbc.connect('DRIVER=SQL Server;'
  'SERVER=my_db_server_name'
  'PORT=my_db_server_port_number;'
  'DATABASE=my_db_name;'
  'UID=my_username;'
  'PWD=my_password')
>>> conn

I am running it both on windows and linux, simultaneously.

The settings components are displayed on the web site.

Works like a charm

One dependency is pyodbc to be installed.

Hi there.

Could you tell me a good way to use Django with Micro Soft DB SQL server. I 
tried django_pyodbc. Any suggestion is appreciated.

my PC of Environment is below.

Database:
SQL Server 2014 Express

OS:
Windows 7 Home Premium SP1

I used the django module, django_pyodbc.
And, I tried to run syncdb but I couldn't.

My settings.py is below.

DATABASES = {
'default': {
'ENGINE': "django_pyodbc",
'HOST': "localhost",
'USER': "djangouser",
'PASSWORD': "x",
'NAME': "db_test",
'OPTIONS': {
 'host_is_server': True,
 'autocommit': True,
 'unicode_results': True,
 'extra_params': 'tds_version=8.0'
 },
}
}

Things I tried and did not work:
1,change "localhost" to "127.0.0.1,1433" in the HOST property of the code.
2,removed 'OPTIONS'.

However, I tried the module pyodbc of pure python like below. It was fine.

---
conn = pyodbc.connect('driver={SQL 
Server};server=localhost;UID=djangouser;PWD=x;DATABASE=shannon_test;Trusted_Connection=yes')

But, DB connection is not established without "Trusted_Connection

Re: Can anyone give me a suggestion or a recommendation as to how I can access the current user's username in the models.py?

2014-12-14 Thread Fred Stluka

Collin and Russell (and anyone else),

Do you have any opinion on this?
- https://bitbucket.org/aptivate/django-current-user

It was offered in an earlier post:
- https://groups.google.com/d/msg/django-users/y7aIbN2_CsA/GtmrSjG1nq8J

as a solution to exactly this problem.

Makes the current user available to the save() method of all
models.

I read the code and it looks good, but I don't know the details
of Apache/WSGI/Django/Python multi-threading well enough
to know if it is thread safe.

It basically uses django.db.models. signals.pre_save.connect()
to get a callback called just before each save(), and that callback
was generated by a middleware layer to know what the current
user was for a request, so it sets a model field with a name like
update_user to the current user just before the save().

If there were 2 concurrent HTTP requests, would this work
reliably? Or would there just be 2 registered callbacks, that
would overwrite each other's values in the update_user field
before the save()? If so, one user would be recorded for saves
done by both requests.

It seems to me that this would work fine if each HTTP request
was handled by a separate process, but not if handled by
separate threads that share the same memory, and presumably
the same signals and callbacks.

Thoughts?

Hi,

The "admin save handlers" refers to save_model() and there's actually
a nice example of accessing the user.

https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.save_model

If you're using the admin, that's a good place to record this sort of
thing.

Using a middleware is also helpful for a more general approach, though
be careful because connections can now be re-used over multiple
requests. Also, if you're deploying using threading, be sure what you
are doing is thread-safe.

Thanks Mike and Russell, this is very helpful for starters. Do you
have some more verbose code examples I can use as crutches while I
hobble along the path of understanding Django? Especially an
expansion on something like "All the admin save handlers" would be
much appreciated.

For me every change needs to be tracked, not just ones from the
admin realm, and the audit trail entry is written by a trigger
function which gets the current user name from a variable set for
the postgres connection. My quest so far was to find the magical
place where I have access to the request (for the username) and
the db.connection (for setting the database variable), which – if
I understand correctly – does not exist. So right now I was about
writing my own middleware class with a process_view. Would that be
the right place and how would I introduce the username into the
data flow?

Re: ANN: Django website redesign launched

2014-12-16 Thread Fred Stluka


Jannis,

Care to summarize what has changed?  At first glance, it looks like
mostly the same excellent content and the same sensible
organization of info, with the same useful mechanisms like the
ability to easily flip between different versions of the docs.

Are the changes mostly to do with CSS styles, colors, fonts,
presentation of info?  Or is there a change to the content or the
navigation, as well?

Thanks!

Re: Content using {% include %} not appearing on detailed page Django

2014-12-16 Thread Fred Stluka


Andrew,

I'm not sure, but since no one else has answered yet...

Maybe you can't pass an object as a keyword argument to include,
can only pass strings?  I've done it often with strings, but never
with an object.  Try:

{% include "sidebar.html" title=object.title %}

and in the included file, use simply:

{{title}}

It seems odd that there'd be a restriction like this since I'm sure
you can pass objects to templates from views, but it's worth
trying.  May be a good workaround, or may get you a different
error message that tips you off to what the real problem is.

Yes, its because the legacy DB has Windows-1252 chars in it, but
mis-informs Django that it is all UTF-8 chars.

Not a problem with django-pyodbc, which seems to work perfectly.

Hi Fred,

Is that because you had a legacy database with Windows-1252 characters

Re: Email Templates and the full website URL

2013-11-30 Thread Fred Stluka

I had the same problem. Wrote this:

def get_web_server_base_url(request, settings_override_name=None):
# Allow the value in the settings file to override any computed value.
url = None
if settings_override_name:
url = getattr(settings, settings_override_name, None)
if not url:
protocol = request.is_secure() and 'https' or 'http'
host = request.get_host()
url = "{0}://{1}".format(protocol, host)
return url

I didn't know about Site or RequestSite at the time. Perhaps I could
have used them, but:

1. I wanted the protocol (http, or https) to be correct also. Would
RequestSite have done that for me?

2. I wanted to be able to override the hostname with the primary
name of the server (via an entry in settings.py) even if the request
was sent to a secondary name or the IP address of the server.
I suppose Site would have allowed this, via storing the name in
the DB, but that seems like more work than a settings.py file,
especially since I already have convenient mechanism to manage
different settings.py files when deployed on different servers.

Thoughts?

Re: Connecting to a MS SQL server from django

2014-01-19 Thread Fred Stluka


Larry,

We tried django-mssql and gave up.  Much better luck with
django-pyodbc.  We use the avidal version of it, along with pyodbc,
FreeTDS, and unixODBC.  Works perfectly.  If you like, I can dig up
my notes on exactly how we made the connection from Django to
MS SQL Server.

I traced it through

defaults to 9099 - Is that the correct port or should I set
os.environ['PROXY_PORT']? How can I tell what port MS SQL db is
listening on? I googled this and it said the default MS SQL port is
1433. I set os.environ['PROXY_PORT'] to that and now I don't get that
error but it times out:

I tried opening port 1433 with iptables, but still no joy.

I can connect to the MS SQL db locally from the host it's running so I
know it's up and my credentials are correct, and I can ping the
Windows box from the Linux host I am running on, so I know there is
connectivity to it from there.

Anyone here ever get this working? Anyone have any ideas as to what my
problem is or how I can debug this further?

Thanks!

## Install all the packages

$ pip install -r requirements.txt

### Mac OS X note

The `pyodbc` package that _pip_ installs uses iODBC by default. We want it
to use `unixODBC`, instead, for a couple reasons.

* First, there are numerous sites on the Internet that make claims such as
  "iODBC is a slightly less desirable ODBC manager than unixODBC"
  
(http://www.cerebralmastication.com/2013/01/installing-debugging-odbc-on-mac-os-x/).

  More people _seem_ to have better luck with `unixODBC`.
* Second, we're using `unixODBC` on Linux, and the configuration is already
  complicated enough. So, why not just use the same approach on both 
platforms?


To get `pyodbc` to use `unixODBC` on the mac, you have to build it from 
source,

and you have to hack the `setup.py`. Here's how to do it.

Create the pyodbc1.patch file containing:

*** setup.py.orig2013-12-19 21:49:10.0 -0500
--- setup.py2013-12-19 21:35:21.0 -0500
***
*** 145,151 

  elif sys.platform == 'darwin':
! # OS/X now ships with iODBC.
! settings['libraries'].append('iodbc')

  # Apple has decided they won't maintain the iODBC system 
in OS/X and has added deprecation warnings in 10.8.

  # For now target 10.7 to eliminate the warnings.
--- 145,151 

  elif sys.platform == 'darwin':
! # OS/X now ships with iODBC. We need unixodbc, however.
! settings['libraries'].append('odbc')

  # Apple has decided they won't maintain the iODBC system 
in OS/X and has added deprecation warnings in 10.8.

  # For now target 10.7 to eliminate the warnings.

Do these steps:

$ . ~/pythons/hhl/bin/activate
$ cd /tmp
$ git clone https://code.google.com/p/pyodbc
$ cd pyodbc
$ patch < pyodbc1.patch
$ pip uninstall pyodbc
$ python setup.py install

## Install the SQL Server ODBC backend

`pip install` does not completely install the SQL Server ODBC backend, so
there's one more manual step. You must manually copy some software within
your Python virtual environment.

$ cd ~/pythons/hhl/lib/python2.7/site-packages
$ cp -r ../../../src/sql-server.pyodbc/sql_server django/db/backends

## Set up your Django environment, by adding this to settings.py:

DATABASES = {
'cf': {
'ENGINE': 'django.db.backends.sql_server.pyodbc',
'NAME'  : '_your_db_name_',
'USER'  : '_your_db_username_',
'PASSWORD'  : '_your_db_password_',
# ODBC DSN defined in /etc/freetds.conf
'HOST'  : '_your_odbc_dsn_name_',
# Ignored for Windows; Required for Linux
'OPTIONS'   : {
# ODBC driver name in /etc/odbcinst.ini
'driver': 'FreeTDS',
},
},
}

## Verify that Python can get to the SQL Server database

At this point, you should be able to open a connection to the HHL test
SQL Server database as follows:

$ python
Python 2.7.5+ (default, Sep 19 2013, 13:48:49)
[GCC 4.8.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyodbc
>>> conn = pyodbc.connect('DRIVER=FreeTDS;'

  'PORT=_your_db_port_number_;'
  'DATABASE=_your_db_name_;'
  'UID=_your_db_username_;'
  'PWD=_your_db_password_')
>>> conn



## Initialize your database

$ python manage.py syncdb

## Fire it up!

Re: Problems Setting Up wsgi and Apache

2014-01-27 Thread Fred Stluka


Mark,

Most likely your Apache server is running as user "apache" in
group "apache", and your Django code is being called by the
Apache server via WSGI, so it is also running as user "apache".

True?

If so, make sure that the files and directories needed by the
Apache and Django code are all accessible to user "apache".

P.S.  "or" vs "nor" -- Yeah, I have a VERY strong background in
English grammar.  Partly because it was beaten into me by
the nuns, and party because I'm such a fundamentally nerdy
engineer type that I found the technique of "diagramming a
sentence" to be fascinating and even fun.

So, I know the difference between an adjective and an adverb,
can cite things like the "present perfect tense", know what a
"dangling participle" is and that you are not supposed to end
a sentence with a preposition, etc.

But, the vast majority of people I meet seem to agree  with
Churchill that such rules are things "up with which we shall
not put" [1], so I rarely correct anyone any more, and have
come to recognize that language is a living evolving thing.
The most common usage is by definition the correct usage,
despite what it says in the Oxford English Dictionary (six
inches thick), "Warriner's English Grammar and Composition",
or the "MLA Handbook" -- all sitting within reach of me
right now).

[1] http://public.wsu.edu/~brians/errors/churchill.html

In fact, I pretty much avoid ever using "nor" or "whom"
because people notice when I do, and change their opinion
of me slightly away from hard-hitting, down-to-earth
engineer, and towards ivory tower academic.

Also, I decided many years ago to never use a full sentence
when a simple phrase will do.

Anyhow, good luck with your Django/WSGI setup!

Any more problems, speak up.

2. The Apache error logs were in /var/log/apache2/error.log and not in 
/var/log/apache2/mom/error.log. APACHE_LOG_DIR was not set.


2. Once I found the error logs, I found this -

I tried removing mod-python as recommended by the django docs, but 
that did not help. So I removed the Debian package for python-wsgi and 
compiled python-wsgi myself.


I am not at the point where I get Forbidden - You don have permission 
to access /mom/inventory on this server. This is progress!! ;)


I guess the current problem is that I cannot run the django app from a 
user account (/home/django/). I added the user django to the group 
www-data, but I still get the forbidden message. I will try moving it 
to /var/www as you have it set up.


Thanks again!

P.S. I got a good chuckle from your signature block - "Open Source:

Leigh,

If it helps, here's a list of questions you might want to answer in
your initial post of each position you are trying to fill:
- Brief description of the company, what it does, what the
work environment is like, etc?
- Brief description of the responsibilities of the position you
are trying to fill?
- Technologies used and skills needed?
- Consultant or FTE?
- Full time or part time?
- How long is the initial contract?
- How long is the project likely to run?
- Approx salary or hourly rate offered?
- Location, and is telecommute an option?

Cal, if Leigh posts only once for each position, and always
includes all of the above info, are you happy with that? If not,
what additional info would you suggest?

I'm a programmer, not a recruiter, but I know a lot of people,
so I get asked often by friends to help them fill positions. I
always insist on specific answers to all of the above before I
agree to do a mailing to any of my lists of hundreds of local
developers. This has kept my subscribers happy.

How to reverse both Django South migrations and source code?...

2014-04-18 Thread Fred Stluka


Django Users,

I'm having a problem reversing a Django South migration while also
reverting my source code to an an older version.  Any help?

Details:

My algorithm for doing a release is essentially:
1.  Update the source files
2.  % python manage.py migrate --all

This works great when moving forward.  Step 1 creates new migration
files.  Step 2 looks in the "south_migrationhistory" DB table to see
which migration files have not yet been run, and runs them.  Simple!

Not so great when moving backwards.  For example, when moving from
release 5 back to release 3.  Step 1 deletes the migration files for
releases 4 and 5, leaving only those for releases 1-3.  Step 2 looks
in the "south_migrationhistory" DB table, and decides to reverse
some of the migrations that have already been run, but the migration
files are already gone.  So it complains about GhostMigrations.

I have a few ideas about how to deal with this, but it must be a common
problem.  What do you folks do?

Thanks!

Re: Is it good idea to transition from MS Access to a webapp? And if so, is Django a good tool to do it?

2016-04-29 Thread Fred Stluka


  
  
Patrik,

Yes, Django can be used for that.  

The "ORM" features and the "templates" and "views" of Django 
make it very easy to do a "CRUD" app for a users to create/
retrieve/update/delete data in any RDBMS.  

There are some built-in security features like logins, protection 
against "CSRF" attacks, etc.  

Django "formsets" make it easy to show multiple rows with a 
details panel for the row currently selected.

With a web app, you won't have to re-distribute the front 
end.  Just push a new version to the server.

Django's templates and views both support "inheritance", 
which should solve your problem of managing multiple 
related forms.  And, there are many Open Source custom 
widgets for Django and for _javascript_ that will give you all
the sub-grouping and tree-views that you need.

Django scales very well to large amounts of data, large 
numbers of screens, and large numbers of users.  There 
are many performance tuning options, including "caching"
of templates, and of fully-constructed pages, and of DB 
data.  Also, lots of other "middleware" for security, 
performance, logging, and other "aspects" of the software.

Yes, you can run a Django server locally, behind a "firewall",
or can expose it to the world, securing various parts as 
needed.

To make it as secure as possible, I'd put in on a Linux server
that is protected by tools like Logwatch, Fail2ban, and 
Tripwire.  See:
- http://bristle.com/Tips/Unix.htm#unix_security
And be sure to redirect all page requests from HTTP to 
HTTPS.

I do all of this and more, including processing financial 
transactions and supporting "multitenancy", restricting 
access by thousands of different users, each to his own data, 
plus "attribute based access control" for cases where data is
shared, at the Web site I'm currently working on:
- http://HelpHOPELive.org

Sorry for all the terms and acronyms, but if you're considering 
writing such an app, you'll need to be aware of them and they're 
all pretty easy to Google.  Feel free to reply with more questions. 


Also, you'll quickly get a feel for Django's power if you go 
through the on-line tutorial at:
- https://docs.djangoproject.com/en/dev/intro/

Enjoy!

  Hi,


I work for a very small company that I developed an

  robust RDBMS, and a front-end app built in MS Access).
  Currently this app is used to calculate the exact wages of
  some employees (sorry, English is not my native language so I
  don't know how that type of wage is called here, but basically
  we look at how many products they produced and calculate it
  based on that. It's not a hourly wage). However, this summer I

  each order has specific products that need to be produced...
  each of those can be produced by our employees and so it's
  directly linked to the wages).


However, it is very hard to manage everything using MS
  Access. Basically each time I make any change to FE or BE, I
  have to re-distribute the FE to all of the front-users. This
  is not a HUGE problem, the big problem, however, is within the
  MS Access itself, that is, it's very hard to manage all the
  forms as they are listed as simple names (ie. you cannot
  sub-group them efficiently to make a tree-view). Overall I
  cannot see myself working with MS Access in 5 years time as I
  can already see the scalability problems after a few months of
  working with it.


What I thought of, however, is making a website that is
  only for local use, but is it possible to have the same
  functionality as a regular front-end app? Is this good idea to

Should be no changes required. I develop on Mac and just copy
my Django files (*.py, *.html, etc.) to my Linux server when
I deploy.

You said you already have the same Django/gunicorn/nginx

Nothing left to do.

Python/Django users,

Any Python and/or Django courses/materials to recommend?

I may be teaching a Python/Django class soon.  My client may be 
willing to jumpstart by buying existing course materials (lecture 
slides, notes, homeworks, labs, reference links, any other
materials).
We'll certainly be happy to make use of any free materials.

Do you have any Python and/or Django courses/materials to 
recommend?

I've taken a quick look and found:
- Main web sites:
  - http://python.org
  - https://djangoproject.com (excellent docs and tutorial!)
- Free courses:
  - https://developers.google.com/edu/python
- Free/paid courses:
  - http://learnpythonthehardway.org/book
- Books
  - 2 Scoops of Django
- Paid courses:
  - Coursera
  - Codecademy
  - Khan Academy
  - Udacity
  - edX
  - Alison
  - Lynda
  - NewCircle.com

Any advice?  Thanks!

Re: Slow Django dev server reload

- Mac OSX 10.11.5 (El Capitan)
- 2.3GHz Intel Core i7
- 16 GB 1333 MHz DDR3
- 512GB SSD
- Python 2.7.3
- Django 1.4.2
- MySQL 5.1.33

And it takes less than a second from when I type:
% python manage.py runserver
until I see:

Validating models...

0 errors found
Django version 1.4.2, using settings 'hhl.settings'
Development server is running at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

I have about 40 models.py files, of which 25 are empty and
exist only to prevent warnings when run automated tests.
The other 15 contain about 100 Django models with a total
of about 27,000 lines of code.

The 100 models all get validated against a locally running
MySQL server.

So, it should NOT be that slow on your Mac.

To narrow down the problem, I suggest you use the -v option:
% python -v manage.py runserver

Re: Slow Django dev server reload

2016-07-05 Thread Fred Stluka


  
  
Krishna,

Only a third of your count -- 551

% tcsh 
  % python -v manage.py runserver >&! ~/1.1
  % grep -E "^import" ~/1.1 | wc -l
 551

So, you didn't see any noticeable pauses as the -v output was
streaming to the terminal window?  Sounds like it's just doing a 
lot of work, not stalling out anywhere in particular.

Why so many imports?  Seems odd that I have more models,
but fewer lines of code, and far fewer imports.  Are all of your
imports still needed?  Or are many of them obsolete and could
be deleted?  We tend to get rid of our dead ones pretty quickly
because PyCharm shows them as grey when they're not needed.

  Hi Fred,


Thanks for providing your project as a reference and also
  the python verbose tip. I just started my dev server with the
  -v option to see how many import statements are fired. grep
  '^import ' returned about 1500 lines in the output (about 75
  models with about 40k lines of code). I could not narrow down
  the problem to any specific import / module. Curious to know

Albert,

Yes, any other app , written in Python or any other language, should
be able to access your relational DB concurrently with your Django
app, if it has the right credentials. This is true for PostgreSQL,

MySQL, Oracle, DB2, or any other RDBMS you might use.

Re: Testing if a view have an html element with at least one attribute

2016-08-03 Thread Fred Stluka


  
  
Ludovic,

On my project, we have lots of test cases that do a GET or POST and

then check the returned HTML.  We use the BeautifulSoup HTML 
parser from our Django tests to avoid the types of errors you're 
getting with simple string comparisons.  I'm not sure if there any
pros/cons vs lxml, but it works great for us!

Database data caching in Django?...

2016-08-17 Thread Fred Stluka


  
  
Django users,

Is there an easy way to enable an automatic write-through 
database cache in Django?

I'd want memcached or something to cache all data read by the 
Django ORM and use the cached copy on future reads, and of 
course update the cache as well as the DB (a "write-through" 
cache) when writing data.

Is there a piece of middleware I can activate to cause the ORM
to do this automatically for all DB queries?  Thanks!

Details:

I'm interested in caching the results of queries to the DB, not 
caching the results of templates or views.  So, it is different 
from the following, which I already know how to do:
- Caching of template files:
   -
http://us5.campaign-archive1.com/?u=a8d4be66d1927077a9255182d&id=a6f7d644a7&e=c90970e145
   -
https://docs.djangoproject.com/en/dev/ref/templates/api/#django.template.loaders.cached.Loader
- Caching of all Django views for an entire site:
   -
https://docs.djangoproject.com/en/dev/topics/cache/#the-per-site-cache
- Caching of specific Django views:
  -
https://docs.djangoproject.com/en/dev/topics/cache/#the-per-view-cache
- Caching of fragments of a Django Template:
  -
https://docs.djangoproject.com/en/dev/topics/cache/#template-fragment-caching

I'm also hoping to not have to add cache API calls throughout my
code, as described here:
-
https://docs.djangoproject.com/en/dev/topics/cache/#the-low-level-cache-api

I'd like the Django ORM to make the API calls for me automatically
when I call objects.get(), objects.filter(), save(), etc.  I'd hoped
to 
enable it simply by adding middleware or a custom manager or 
something.

Any suggestions?  I feel like I may be missing something obvious.

cut_off_date = models.DateField(null=True, blank=True)
ballot_date = models.DateField(null=True, blank=True)
sess_no = models.ForeignKey(Session,
 on_delete=models.CASCADE)
genre = TreeForeignKey('Genre', null=True, blank=True, db_index=True)
I use def get_shift_date(self):return self.sit_date=self.shift_date

Re: Unable to get tests to work

2016-08-17 Thread Fred Stluka

Matt,

Oops! Right. I just noticed that in the dpaste.

My next guess is you may need to change the name

"good_index_text"
to something that starts with "test_" to get it to be recognized as
a
test.

Or maybe something to do with "refreshes"? The test trace shows
it trying to run testcase "refreshes.backups.tests", but in the
manual
import you did from the python shell, you only import
"backups.tests"

Re: Unable to get tests to work

2016-08-19 Thread Fred Stluka


  
  
Matt,

At a glance, the directory structure looks OK.  Seems odd though
that you have some *.pyc files with no corresponding *.py file.
For example, frontend/tests.pyc and nas/tests.pyc.  Could such 
a file be tripping up the test runner?  That might explain why it 
fails when no arguments -- searching for all tests and getting 
confused -- but succeeds when told to run only backups.tests.

Same for all of the erp/*.pyc files.

Perhaps try deleting all *.pyc file in the entire tree and then run
the tests, letting them be recreated from the *.py files as needed.

Also, I see a backup/tests.py with no *.pyc file.  Is there a syntax

error in that file that makes it not compile?  Or is it just not 
getting that far?

Also, what is in pytest.ini?  Is it perhaps directing the test
runner 
to look for tests that don't exist?

Re: Help with django form an ajax, error 500

2016-08-21 Thread Fred Stluka


  
  
Elros Romeo,

Can you see the log file?  It may show details of the 500 error,
which will likely be some error reported by your Django code.
Could be anything from a Python syntax error to a failed attempt
to connect to a DB, to a misconfigured settings file, or anything 
else.
