Re: Noob: How do I get this app to work :(

[Kelvin Wong]

If you have old code, you can still use it with an older Django using the 
pip installer

$ pip install Django==1.3.7

Re: new to Django and building web applications. Advice with postgresql

[Kelvin Wong]

You don't have to become an expert with postgres to use Django. You can do 
most of the db development using SQLite and hold off on postgres until you 
are ready to deploy.

I'd get a Linux server running in VirtualBox. Install Apache and postgres. 
Configure postgres. Install phpPgAdmin.

If you are going to be looking for a job doing Django, your employer will 
want you to know Django and Python really well, not postgres.

Re: working with images in django

[Kelvin Wong]

So you have images already made and you want to place them into HTML? 
That's easy. If you want to make the image dynamically using something like 
PIL or Pillow then flow them into a PDF then that's a little more involved.

Try explaining your use case a bit more.

Re: Help getting started: Which server setup for a beginner? Apache? lighttpd? To use or not virtualenv?

[Kelvin Wong]

It is def worth taking the trouble to learn how to use virtualenv and 
virtualenvwrapper. Once they are set up and assuming that you haven't 
already put too much already into your global site-packages, they will save 
you time and greatly simplify keeping different project environments 
separate.

You didn't mention if you were on a Mac or what. On a UNIX dev machine 
setting up virtualenv and the wrapper are fairly straightforward.

Re: problem with deploying django using mod wsgi

[Kelvin Wong]

Is your form (on page /mice/search_mice/) submitting to

/mice/search

or

/search

Check your form element in the html document. Is it pointing to the right 
URL?

Maybe check your WSGIScriptAlias setting. Maybe verify your DocumentRoot 
setting.

You might also want to check the request and response using a tool like 
HttpFox

Re: Error importing middleware django.contrib.sessions.middleware

[Kelvin Wong]

Did you do this part (from the docs):

https://docs.djangoproject.com/en/1.5/topics/http/sessions/#using-database-backed-sessions
Using database-backed 
sessions

...

Once you have configured your installation, run manage.py syncdb to install 
the single database table that stores session data.

---

If that doesn't help then, you could try using the Django shell and looking 
for exception that comes up:
$ python manage.py shell

>>> middleware_path = 'django.contrib.sessions.middleware.SessionMiddleware'
>>> mw_module, mw_classname = middleware_path.rsplit('.', 1)
>>> mw_module
'django.contrib.sessions.middleware'
>>> from django.utils.importlib import import_module
>>> mod = import_module(mw_module)

Re: Django Gunicorn with Two Django App

[Kelvin Wong]

The error "Could not reliably determine the server's fully qualified domain 
name" is harmless, but the fix is easy. See...

https://help.ubuntu.com/community/ApacheMySQLPHP#Troubleshooting_Apache

If you are running Django under Nginx and Gunicorn, why are you restarting 
Apache anyway?

Your gateway issue is very common with Nginx and can be fixed by proper 
configuration of your reverse proxy and ensuring that your Gunicorns are 
actually running and handling traffic. I've used Supervisor to manage the 
Gunicorns and it works well for that purpose.

http://wiki.nginx.org/HttpProxyModule

http://docs.gunicorn.org/en/latest/deploy.html

If you find the reverse proxy set-up too confusing, I'd recommend mod_wsgi. 
I find it easier to set-up and manage than other methods.

Re: tests failing/throwing errors - not sure where to start

[Kelvin Wong]

My advice to you is to just ignore it all and focus on the tests in your 
application.

For example, if your app that you wrote yourself is called "amazingapp" 
then you test only that app thus.

---

$ python manage.py test amazingapp

---

And it will say something similar to this...

---

Creating test database for alias 'default'...
.
--
Ran 1 test in 0.002s

OK
Destroying test database for alias 'default'...

---

Don't bother testing your framework code or your modules, which Django does 
if you leave out the app name (assuming you're not making patches for 
Django itself).

PS. Good for you for testing your code.

Re: Using an external Server to serve Static files - Development Server

[Kelvin Wong]

This is how I do it.

In settings.py:

STATIC_ROOT = '/home/user/app/site_media/static/'  # Generated files here 
from 'manage.py collectstatic'

STATIC_URL = 'http://static.example.com/static/'

In templates:

{% load staticfiles %}

...



Produces:

http://static.example.com/static/myapp/stylesheets/app.css"; 
rel="stylesheet" type="text/css">

If static.example.com is behind Nginx this is in your static server conf 
file:

# Nginx staticfiles setting

location /site_media/ {
  alias /home/user/app/site_media/;
}

This is a made up example, but the real thing is close to it.

Re: Admin: Add new dataset with a pre-selected foreign key?

[Kelvin Wong]

Take a look at filters in the admin. You might be able to add log entries 
to recent items using an appropriate ModelAdmin on 'entry_created'

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

Then use an InlineModelAdmin

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

You could then select the sample by finding recently added samples, 
clicking on it, then add the log entry

Re: New to Django and developing website based on a Framework. What is the best order to develop website?

[Kelvin Wong]

Add features as you need them. If you are going to launch in multiple 
languages I'd add that early on. Adding the stock authorization is pretty 
safe as well.

Learn and use the testing framework as much as possible.

Re: Django logs for the website

[Kelvin Wong]

It depends on how you're running your Django app. If you are running this 
under Apache mod_wsgi, they end up in the Apache error.log file. If you are 
running this under Gunicorn/Supervisor with an Nginx out in front then I've 
seen them show up in the Supervisor log file.

I've also seen them emit messages to a network logging machine. It depends 
how you set up your loggers.

Re: Django-registration reset password templates not getting picked up

[Kelvin Wong]

TEMPLATE_DIRS needs to have the location of the templates. As long as those 
templates are being picked up and one is called 'password_reset_form.html' 
it should work.

One of my apps has this form at:

/my_project/templates_global/registration/password_reset_form.html

In /my_project/my_project/settings.py

PROJECT_ROOT = os.path.abspath(os.path.dirname(os.path.dirname(__file__)))

TEMPLATE_DIRS = (
os.path.join(PROJECT_ROOT, 'templates_global')
)

The templates were all copied 
from django.contrib.admin.templates.registration

Re: Django-registration reset password templates not getting picked up

[Kelvin Wong]

Check that your 'homepage' app is above the 'registration' app:

INSTALLED_APPS = (
'homepage',  # Order matters, this is loaded before others
'registration',
'django.contrib.auth',
   ...
)

Order of the apps is significant. Review

https://docs.djangoproject.com/en/dev/ref/templates/api/#django.template.loaders.app_directories.Loader

As a matter of personal style, I would put them in a project template 
folder and not in an app templates folder.

Re: Django-registration reset password templates not getting picked up

[Kelvin Wong]

I put the overridden templates (auth, registration, etc) in a project 
templates folder in the project root. You have to set it up though in your 
settings.py as I noted earlier. The filesystem loader is still right there 
above the app_directories loader. To me the overridden templates don't seem 
to make sense in an app even if it does nothing but serve the homepage.

Templates that belong to certain apps are put into application templates 
folders. That makes more sense to me.

This is just personal dogma though.

Re: Do I always have to run collectstatic to serve uploaded images by apache?

[Kelvin Wong]

The MEDIA_ROOT is the local system location where the FileField in your 
models is going to store incoming files. Users submit files and they are 
placed in the location specified by the 'upload_to' setting of the field 
(usually a directory within MEDIA_ROOT).

https://docs.djangoproject.com/en/dev/ref/models/fields/#django.db.models.FileField.upload_to

You should remove your MEDIA_ROOT from STATICFILES_DIRS.

Then you should review this documentation.

https://docs.djangoproject.com/en/dev/topics/http/file-uploads/

The 'collectstatic' command collects your static assets, not user submitted 
content. Your system is misconfigured and that is why it is collecting user 
submitted files.

Your MEDIA_ROOT setting is also suspect.

As-is you will be writing user submitted files into your shared 
site-packages folder. Hopefully you won't be running Django as root and 
you'll get a permission error.

Re: Do I always have to run collectstatic to serve uploaded images by apache?

[Kelvin Wong]

Check your templates. I bet your tag there is giving the wrong root 
relative path to the user uploads.

https://docs.djangoproject.com/en/dev/ref/templates/builtins/#get-media-prefix

If Apache is giving you problems, what does it say in your Apache logs? Try 
debugging this like you would an Apache configuration error.

Re: static files are not working

[Kelvin Wong]

Are you saying that your settings are like this?

STATIC_ROOT = 
'/usr/local/lib/python2.7/dist-packages/django/contrib/admin/static'

STATIC_URL='/static/'  # < Trailing slash required! check it

If so that is asking for trouble when you do a collectstatic. You'll prob 
get permission error unless you do a sudo.

Set your STATIC_ROOT somewhere you can write to without sudo when you do a 
manage.py collectstatic:

STATIC_ROOT = '/var/www/myproject/site_media/static'

if your deployment files are at /var/www/myproject

Review...

Re: Django unittest failure

Are you reusing an old database or something? There should be only two

self.normal_user = User.objects.create(username='test1',

Re: Django unittest failure

[Kelvin Wong]

You should probably open a bug on this issue. The test suite fails for me 
on MacOS/Python 2.7 on the stable/1.5.x branch. This is the command that 
fails reliably on my machine:

$ PYTHONPATH=..:$PYTHONPATH python ./runtests.py --settings=test_sqlite 
utils formtools

It might be related to this addition

https://github.com/django/django/commit/cb9aaac

The user created by this line (l.129):

user = User.objects.create_user('johndoe', 'j...@example.com', 'pass')

... persists into subsequent WizardFormKwargsOverrideTests tests on 
the stable/1.5.x branch

Running the individual test for 'formtools' passes without issue.

Re: Trouble with STATIC_URL in v1.5.2

[Kelvin Wong]

Check that your STATIC_URL setting in your template is outputting the same 
string as settings.STATIC_URL. Make sure that any included 
local_settings.py files are not wiping out those settings. You can check it 
using the Django shell:

$ python manage.py shell

>>> from django.conf import settings
>>> settings.STATIC_URL
'/assets/static/'

If not, check that you're using RequestContext to render your views. You 
can do this from the Django shell as well.

>>> from django.http import HttpRequest
>>> r = HttpRequest()
>>> from django.template import Template
>>> t = Template("{{ STATIC_URL }}")
>>> from django.template import RequestContext
>>> c = RequestContext(r, {})
>>> t.render(c)
u'/assets/static/'

Check that you're including 'django.core.context_processors.static'  in 
your settings.TEMPLATE_CONTEXT_PROCESSORS tuple.

>>> settings.TEMPLATE_CONTEXT_PROCESSORS
('django.contrib.auth.context_processors.auth', 
'django.core.context_processors.debug', 
'django.core.context_processors.i18n', 
'django.core.context_processors.media', 
'django.core.context_processors.static', 
'django.core.context_processors.tz', 
'django.contrib.messages.context_processors.messages')

Re: Trouble with STATIC_URL in v1.5.2

[Kelvin Wong]

If your software works then I guess it works, but I just ran this in the 
shell on Django 1.5.4.

$ python manage.py shell
Python 2.7.3 (default, May  4 2012, 11:07:18) 
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from django.conf import settings
>>> settings.STATIC_URL
'/static/'
>>> settings.DEBUG
False
>>> from django.http import HttpRequest
>>> r = HttpRequest()
>>> from django.template import Template
>>> t = Template("{{ STATIC_URL }}")
>>> from django.template import RequestContext
>>> c = RequestContext(r, {})
>>> t.render(c)
u'/static/'
>>> import django
>>> django.get_version()
'1.5.4'

If you look at django.core.context_processors you can see that the 
STATIC_URL is placed in the RequestContext unconditionally on line 65:

https://github.com/django/django/blob/stable/1.5.x/django/core/context_processors.py

Re: Implementation of a Search Engine. How??

[Kelvin Wong]

Look up Solr because it does everything you want. You can crawl with Nutch. 
Django can be used as a front end to that.

Re: View not working / how can I test it in the shell?

[Kelvin Wong]

You need to understand what ALLOWED_HOSTS does if you want to ever deploy 
your app. Please read it.

https://docs.djangoproject.com/en/1.5/ref/settings/#allowed-hosts

Check your settings in the shell

>>> from django.conf import settings as s
>>> s.DEBUG
True
>>> s.ALLOWED_HOSTS
['.example.com', '192.168.0.2']

If your DEBUG is False and your ALLOWED_HOSTS is an empty list [] then you 
will not get far. You will get a "SuspiciousOperation: Invalid HTTP_HOST 
header (you may need to set ALLOWED_HOSTS)" message.

You can try putting something like this into the template (pretty much 
straight from the Django blog example), and it will tell you nicely when it 
has nothing matching your query or if your db is empty:

{% block featured_posts %}
  {% if featured_posts_list %}
{% for blog_post in featured_posts_list %}
{{ blog_post.title }}

{% endfor %}
  {% else %}
No posts found
  {% endif %}
{% endblock %}

You might also want to ensure that your view is rendering the right 
template and that the template hierarchy is correct (ie. {% extends 
"my_templates/base.html" %} is at the top of your template and it is 
correct). If your parent template that you're extending doesn't have a 
block named 'featured_posts' then it won't display anywhere. You won't see 
the "No posts found" message nor will you see your list of blogs - nada.

If there is an exception in the shell, it will print out a trace. This is 
an actual Dj1.5 trace from a made up exception I planted in the view. You 
can also put objects like your queryset into the Exception message and see 
if your set is producing what you think it should be.

>>> from django.test import Client
>>> c = Client()
>>> c.get('/')

Internal Server Error: /
Traceback (most recent call last):

Re: unable to access django development server on firefox/chrome

[Kelvin Wong]

You can also try this

$ python manage.py runserver 0.0.0.0:8000

You can get your IP from ifconfig, open that in a browser (it might be 
192.168.0.10, etc). You can test your site from another machine in this way

Re: add custom action button on each admin row

Take a look at Admin Actions. It should be able to do what you are thinking.

You can also make a Admin-only view and tie it into the admin.

Re: Read a csv file and save data in postgresql

Looking at your code, maybe this one is better

This thing will make a dict, which you can make into a object by feeding it

Re: Porting to Django Linux with SQL Server Backend

[Kelvin Wong]

I have a working system running Django 1.6/Python 2.7 on RHEL 7 connecting 
to MSSQL2012 SP 2 on Win Server.

On the Linux box we are installing this with Pip requirements:

 git+https://code.google.com/p/pyodbc@3.0.7#egg=pyodbc
 django-pyodbc-azure==1.1.5

The local_settings.py contains:

DATABASES = {
"default": {
...
"HOST": "192.168.0.10",
"PORT": "",
"OPTIONS": {
"driver": "FreeTDS",
"dsn": "sqlserverdatasource",
'host_is_server': True,
'autocommit': True,
'unicode_results': True,
'extra_params': 'tds_version=8.0'
}
}
}

We are running the latest FreeTDS from 2011.

$ tsql -C
...
freetds v0.91

We've had quirky problems with it and a few mysterious segfaults on the 
application server from time to time. It does work for the most part, but 
the application isn't under any kind of load at the moment.

If I had a choice, I wouldn't run Django on MSSQL Server.

Your options are limited if you want to connect to a 2012 SQL Server. The

Re: Installing django on red hat linux box

[Kelvin Wong]

Take a look at the Software Collections (ver 1.1 works on RHEL 7)

http://developerblog.redhat.com/2013/01/28/software-collections-on-red-hat-enterprise-linux/


$ sudo yum install python33-python-devel
$ scl enable python33 bash

You can then install everything locally in your application user's home 
directory.

This snip is from a virtualenv build script. I use virtualenvs on my 
deployments.

$ curl https://bootstrap.pypa.io/get-pip.py | python3.3 - --user
$ echo 'export PATH=$HOME/.local/bin:$PATH' >> $HOME/.bash_profile
$ source ~/.bash_profile
$ which pip
/home/youruser/.local/bin/pip

$ pip install --user virtualenv virtualenvwrapper
$ echo 'source $HOME/.local/bin/virtualenvwrapper.sh' >> $HOME/.bash_profile
$ source ~/.bash_profile

Re: template url reverse and namespacing is driving me crazy

[Kelvin Wong]

Change all instances of this in your templates

{% url 'greet' greeter.pk %}

To this

{% url 'greeter:greet' greeter.pk %}.

Since you are now using the 'greeter' namespace. Also, the other one is 

{% url 'greeter:list' %} and not {% url 'list' %} because you are using the 
'greeter' namespace.

Re: Error: 'NoneType' object has no attribute 'strip'

[Kelvin Wong]

Post the full trace. I looked at the source for auto slug field and they 
don't use strip, so the source of this error must be somewhere else. You 
are looking for code like this:

slug = None
slug.strip()

Re: Database Error (SQLite) Database is locked

[Kelvin Wong]

You can try finding the lock (assuming you are on unix):

$ which fuser
/usr/bin/fuser

$ fuser db.sqlite3 
db.sqlite3: 84349

$ ps aux | grep 84349
kelvin   84349   0.0  0.1   491220   4776   ??  SFri03PM   3:24.57 
/Applications/SQLite Database Browser.app

This shows candidates that might have locks on the db. You can try closing 
them or killing them (ie. kill 84349)

fuser - list process IDs of all processes that have one or more files open

Re: Nesting custom template tags

[Kelvin Wong]

You might want to look at the code for making a tag like:

URLNode(Node)

line 408 of

https://github.com/django/django/blob/stable/1.6.x/django/template/defaulttags.py

Then extend that.

class MyAnchor(URLNode):

override the init function to accept the params your are sending and 
override render so that it returns the HTML that you want.

{% my_anchor URL %}this is text between opening and closing tags{% 
end_my_anchor %}

would yield

this is 
text between opening and closing tags

Re: django on rhel5 with both python2.4 and python2.7 confusion

[Kelvin Wong]

Question one...

The gist is:

1. Set up Virtualenv and Virtualenvwrapper (lots of howtos on the web for 
this - find one written in the last year)
2. Set correct environment keys to point to the right Python (similar to 
the following, you paths may be different)

# ~/.bashrc
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python2.7
export VIRTUALENVWRAPPER_VIRTUALENV=$HOME/.local/bin/virtualenv-2.7
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Projects
source $HOME/.local/bin/virtualenvwrapper.sh

3. Make a virtualenv: like this $ mkvirtualenv myappenv
4. Install Django into the virtualenv (you should have been dumped into it 
after you made it): (myappenv) $ pip install Django
5. Check which django-admin.py you are using

$ which django-admin.py
/home/myuser/.virtualenvs/myappenv/bin/django-admin.py

Hint: Webfaction uses CentOS with many different types of Pythons. 
Searching their support website may be helpful.

---

Question two: Use mod_wsgi rather than mod_python. See warning at the top 
of the Dj1.4 docs

https://docs.djangoproject.com/en/1.4/howto/deployment/modpython/

Setting up a Django app is more complex than setting up a PHP app (one 
persons opinion). The benefit is that at the end of the ordeal you will be 
running Python and not PHP (one persons opinion).

:)

Re: Registration in 1.8

OP is new to Django. There are tons of old blog posts, working code, etc 
dealing with registration and basic app set-ups using 1.4.

Also Django-registration works with 1.4, does it work with 1.6?

Re: Django RequestFactory() secure not working

[Kelvin Wong]

If you print out your code you will see that you are adding a key-value to 
the WSGI environ:

# print factory.post('/', secure=True)

,
POST:,
COOKIES:{},
META:{
 ...
 'PATH_INFO': u'/',
 ...
 'REQUEST_METHOD': 'POST',
 ...
 'SERVER_PROTOCOL': 'HTTP/1.1',
 'secure': True,
 ...
 'wsgi.url_scheme': 'http',
 ...
>

This is because factory.post has the following parameters:

post(path, data={}, content_type=MULTIPART_CONTENT, follow=False, **extra)

Your secure=True gets pushed into extra and it appears in the environ as 
expected.

The solution for modeling TLS requests is to set the 'wsgi.url_scheme' to 
'https' using an unpacked dictionary.

# obj = factory.post('/', **{'wsgi.url_scheme': 'https'})
# print obj
# print obj.is_secure()

,
POST:,
COOKIES:{},
META:{
 ...
 'PATH_INFO': u'/',
 ...
 'REQUEST_METHOD': 'POST',
 ...
 'wsgi.url_scheme': u'https',
 ...
>
True

Re: django on rhel5 with both python2.4 and python2.7 confusion

I haven't used mod_python in such a long time that I don't recall the

to add the Python 2.7 site-packages folder to the path that mod_python 
searches for python modules like Django.

Also, check this out on SO.

Re: Django queryset csv encode

Try

The other returns one-tuples in a list

Re: Django queryset csv encode

[Kelvin Wong]

Okay, I re-read your first post. You said that you wanted to get a UTF-8 
string.

name = [name.encode("utf8") for name in Staff.objects.filter(id = 
3).values_list('user_name', flat=True)]

This variable 'name' now contains a UTF-8 encoded string in a list-like 
object.

Re: Django queryset csv encode

[Kelvin Wong]

If you want all the user_name's in Staff as UTF-8:

staff = Staff.objects.all()
staff_list = [s.user_name.encode('utf-8') for s in staff]

I'm not familiar with the encoding you mentioned in your last message. Try 
it.

Re: hoping for a quick code review of a few simple class-based generic views

[Kelvin Wong]

I'd recommend removing the login_required checks from the views. Put them 
in the UrlConf instead:

from django.contrib.auth.decorators import login_required

from yourapp.views import MyListsView

urlpatterns = patterns('',
url(r'^$', login_required(MyListsView.as_view()), name='yourapp_list'),
)

This will allow you to write simpler tests for your views.

http://tech.novapost.fr/django-unit-test-your-views-en.html#don-t-decorate-views-in-place

Also, if you restrict your queryset to display only objects for the current 
user then the generic view will be smart enough to return Http404 for 
requests for object pks that they do not own. Depending on your models, you 
might need to write a Manager for it.

class ItemDetailView(DetailView):
model = ItemModel
template_name = 'cmv_app/item_detail.html'

def get_queryset(self):
q = self.model.lists.for_user(self.request.user)
return q

Re: Help - Django App on Heroku & local dev machine

[Kelvin Wong]

Clone the app locally

http://stackoverflow.com/questions/1872113/how-do-i-clone-a-github-project-to-run-locally

Create a virtualenv

http://virtualenv.readthedocs.org/en/latest/virtualenv.html#usage

Install your requirements

$ pip -r your_app_path/requirements.txt

Run the dev server

https://docs.djangoproject.com/en/1.6/ref/django-admin/#runserver-port-or-address-port

To get the code back on the machine, look for a fabfile and use it, or just 
push to origin and update it manually over SSH.

If you don't already know Python or Django, I'd recommend

Re: Custom user model backend

[Kelvin Wong]

Maybe try putting some logging in your CustomUserModelBackend.

Near the top, put in some logging boilerplate:

import logging
logger = logging.getLogger(__name__)

Then in your backend, something like this:

class CustomUserModelBackend(ModelBackend):
...
def get_user(self, user_id):
try:
return self.user_class.objects.get(pk=user_id)
except self.user_class.DoesNotExist:
logger.info('User.id={}: User not found, attaching 
AnonymousUser'.format(user_id))
return None

This backend method is checked by the AuthenticationMiddleware when it 
attaches the user to the request

https://github.com/django/django/blob/stable/1.6.x/django/contrib/auth/middleware.py#L18

https://github.com/django/django/blob/stable/1.6.x/django/contrib/auth/__init__.py#L133

When you make a backend like this it is also a good idea to make a test 
suite for it.

If these are all fruitless, maybe try looking at your session setup. I'm 
assuming you are running the db backend for the sessions. If you are using 
memcached or something else, check the usual settings (TIMEOUT, OPTIONS, 
etc)

Re: reverse function

[Kelvin Wong]

The functions reverse and reverse_lazy are useful for figuring out the 
paths from labels. If you or someone else changes the urlconf in the 
future, your app uses the new paths without difficulty.

If you have in your urls.py

url(r'^home/$', views.home, name='home'),
url(r'^specifics/(?P\d+)/$', views.detail, name='detail'),

Then in your views.py you have:

print reverse('home')
# prints /home/

print reverse('detail', args=[12])
# prints /detail/12/

As for render_to_response, it is still there and everybody still uses it.

Re: Django Template - problema

[Kelvin Wong]

In relacaoconjugetipouniao_form.html

Add this tag...then refresh...

{{ form.fields }}

Should give you more info about what fields are in the form and what widget 
they are using.

ie. 'tipo_conjuge': django.forms.fields.TypedChoiceField object

Also check your html source in a browser. Sometimes CSS mistakes hide 
things.

Re: Registration extend nightmare

[Kelvin Wong]

This is not an answer to your question, but I have used Django-registration 
before and ran into its limitations. Consider all the time you spent trying 
to debug this then consider that you'd probably already be done if you had 
just wrote a custom user and maybe salvaged some of the nicer code 
from Django-registration.

I've seen that error before. I seem to recall it comes from the way 
postgres handles transactions when one part of the transaction craps out. 
You might find some good info if you search for that specific message with 
the term postgres. Maybe also review the docs on Django transactions.

https://docs.djangoproject.com/en/1.6/topics/db/transactions/

At the very top of the models.py file add:

Re: HELP on unittest.loader.ModuleImportFailure

You need to be in the first superlists directory. You have a db created so 
you must have run syncdb at some point. Go back to that folder:

$ pwd
/home/you/superlists

$ ls
__init__.py   db.sqlite3superlistslistsmanage.py

$ ls lists/tests.py
lists/tests.py

$ python manage.py test

Creating test database for alias 'default'...

Re: HELP on unittest.loader.ModuleImportFailure

[Kelvin Wong]

Find out which versions you are using

$ python --version
Python 2.7.6

$ django-admin.py version
1.4.10

Try importing the lists app from the shell

$ python manage.py shell

Python 2.7.6 (default, Jan 13 2014, 04:26:18) 
[GCC 4.2.1 (Apple Inc. build 5577)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> import lists
>>> lists.__file__
'/users/you/superlists/lists/__init__.py'
>>> from lists.tests import *
>>>

If you see all that, run the lists app explicitly by label

$ python manage.py test lists

If that doesn't work, maybe there is something weird in your manage.py 
messing the paths. Paste it.

Re: HELP on unittest.loader.ModuleImportFailure

[Kelvin Wong]

Open this file

/Users/kim/Desktop/Python/python3/superlists/lists/tests.py

On line 3 change

from superlists.lists.views import home_page

to

from lists.views import home_page

For the future, check your paths with the following

import sys; print(sys.path)

Re: Can't get MySQLdb

[Kelvin Wong]

You better check that the MySQL connector actually runs on Py3. I recall 
reading that it does not run on Py3.

I don't use MySQL with Django though. Maybe someone else familiar has 
better info.

Try to import it from the shell.

Re: Expected URL with primary key when testing SimpleTestCase.assertRedirects()

[Kelvin Wong]

This is how I usually do redirect tests:

self.assertEqual(response.status_code, 302)
self.assertRedirects(
response,
'http://testserver' + reverse('pizza:deleted')
)

I recommend using named URLs, that way your message_id would be similar to 
this:

reverse('pizza:delete', args=[pizza.id])

Here is the complete app's tests if you want to take a look

Re: page not found errors for most urls but main landing page displaying okay

[Kelvin Wong]

If you have access to your logs, check your logs to figure out where those 
requests are going.

You can also SSH into the server and temporarily turn on the DEBUG=True, 
TEMPLATE_DEBUG=True and let Django tell you what is going on.

Without seeing your fcgi script, my guess is that it is Apache not mapping 
the request to your WSGI file/fcgi script. Double check your htaccess file 
mod_rewrite directives.

Re: crm app

[Kelvin Wong]

If you don't want to help the fellow when he runs into issues, give him a 
supported product like Zoho CRM. It is free for 3 users.

I'm currently reviewing Tree.io for a client and while it looks nice, it 
uses Piston (abandonware), Jinja (unnecessary), Dajaxice (a bad idea 
generally). I wouldn't recommend it at this point.

Re: crm app

[Kelvin Wong]

I've not used Django-CRM.

I've used Salesforce in the past, but it is even more overkill than 
SugarCRM. It is incredibly flexible though. It depends on what your 
client's requirements are.

Keep in mind what they are going to do for on-going support (backup, etc). 
Non-tech users always need support and training. As developers it is easy 
to take this for granted.

Re: Installing MySQLdb for python2.7 in RHEL 6

[Kelvin Wong]

You need to locate the header files in order for that to compile.

You might want to see if they are located somewhere on your system by using 
'find' or else check 'yum list installed' to see if you have already 
installed the mysql devel package for your version of the database server 
(i'm guessing that you haven't got the headers).

If you haven't got them on your machine then you have to install them.

Re: Installing MySQLdb for python2.7 in RHEL 6

[Kelvin Wong]

You are mixing the repos (remi and the regular redhat one). You should 
decide which one you want to use for mysql and stick to it.

The remi repo has the devel package available

http://rpms.famillecollet.com/enterprise/6/remi/x86_64/repoview/applications.databases.group.html

You can isolate a repo to see what it offers

$ yum --disablerepo "*" --enablerepo "remi" list available
