Three table Lookup Question

[Kyle]

Hello!

I am trying to get a list of "Projects" based on certain "Industry".
(My naming convention, not django's)

My models look like this:
http://dpaste.com/114308/

"Project" has a foreign key to "Campaign".

"Industry" also has a foreign key to "Campaign".

Does it matter if both relationships are pointing to the center model
in the data route I am trying to setup?  Like this:

Project -> Campaign <- Industry

If Industry = 3, and a handful of Campaigns are returned, I would like
a list of all the Projects contained in each of the Campaigns
returned.

How do I do this with django models?

Re: Three table Lookup Question

[Kyle]

Yes, almost.  It got me to understand the correct syntax.

I noticed that my results were coming according to Industry's primary key,
rather than the Industry integer field, so I appended another __industry

Here is the solution:

Project.objects.filter(campaign__industry__industry=x)

Thank you for your guidance, Todd.

Re: Three table Lookup Question

[Kyle]

Hello again.

I have one more question about the three table lookup I am trying to
complete.

The details of my situation are posted here: http://dpaste.com/115244/

Does anybody have any idea on how to use django's ORM to perform two INNER
JOINS, a WHERE, and an ORDER BY?

Thanks in advance for any help and further guidance!

How to pass a raw ORDER_BY command or function call to a results query object?

[Kyle]

Without any filtering, I can execute the following SQL query to get my
ordered data:
   SELECT * from EXECUTION_JOB ORDER BY GREATEST(startTime, queueTime)
DESC;

But in Django, it seems like the order_by only likes passing of field
names, not a function call.
Is there a way to have it bass a raw ORDER_BY value to the query?

I am getting my filtered query in a variable called "jobs"
I tried calling
jobs.order_by('GREATEST(startTime,queueTime)')
but this fails due to:
   FieldError: Invalid order_by arguments:
['GREATEST(startTime,queueTime)']

Recommended Django development companies

[Kyle]

I'm looking for companies on-par with PivitolLabs (which is Rails
focused) but that focus on python web stacks, particularly Django.
Can anybody offer recommendations?  I'd greatly appreciate it!

New to Django, sheet music organization site

[Kyle]

I am wanting to create an app that helps me organize sheet music. I
want to be able to sort by the artist. Every piece of sheet music I
have I want to be scanned in and uploaded as an image file, then when
I want to open a particular file, it opens as a PDF.

This would be my long terms goals. For now since I am new to Django, I
just want to simply organize my music and be able to easily sort.

I know I will need:

from django.db import models

class Artist(models.Model):
name = models.CharField(max_length=30)
genre = models.CharField(max_length=30)

class Song(models.Model):
name = models.CharField(max_length=30)
artist = models.ForeignKey(Artist)

What else can I do to help me get a start with this? I've gone through
the tutorial and I understand how Django works, its just a matter of
getting some hands on experience.

Thanks for any help.

Re: New to Django, sheet music organization site

[Kyle]

Ok I have a good start. I have run into a problem though. In my
database, I have an artist field. Most artists have a space in there
name. When creating my URLs, how can I ignore white space?

For example, take the artist Chris Tomlin. In my database, it will
show as "Chris Tomlin", but I don't want to type "music/Chris Tomlin"
to access it, I want to type "music/christomlin" or "music/
chris_tomlin". How can I do this?

Thanks.

Re: New to Django, sheet music organization site

[Kyle]

Thank you very much! You have been very helpful. I have, however, run
into another problem.

When I try to access my Object, I get an error "invalid literal for
int() with base 10". I know it has something to do with ForeignKeys,
but cannot find how to fix it.

**models.py**--

from django.db import models

# Create your models here.

class Artist(models.Model):
name = models.CharField(max_length=100)
slug = models.SlugField(unique=True)

def __unicode__(self):
return self.name

class Album(models.Model):
name = models.CharField(max_length=200)
artist = models.ForeignKey(Artist)

def __unicode__(self):
return self.name

class Song(models.Model):
name = models.CharField(max_length=100)
artist = models.ForeignKey(Artist)
album = models.ForeignKey(Album)
date_added = models.DateField('date added')

def __unicode__(self):
return self.name

**views.py**--

from music.models import Song
from django.shortcuts import render_to_response

# Create your views here.

def index(request):
artist = Song.objects.all().order_by('name')
return render_to_response('music/index.html', {'artist': artist})

def artist(request, myartist):
myArgs = Song.objects.all().filter(artist=myartist)
return render_to_response('music/index.html', {'artist': myArgs})

Thanks

lighttpd and fcgi issues

[Kyle Hayes]

Ok, so after the recommendation of the folks on #slicehost, I moved my
two php sites from apache to lighttpd since I planned on also setting
up a new Django site in addition.

The move for the php blogs was very smooth and they are up and
running. However, I can't say the same for my django site and fear
that I must be missing something crucial.

Here is the excerpt from my lighttpd.conf where my Django site is
configured:

$HTTP["host"] =~ "breezyduck\.com" {
  server.document-root = "/home/breezyduck/http/BreezyDuck"
  server.errorlog = "/var/log/lighttpd/breezyduck/error.log"

fastcgi.server = (
"/admin.fcgi" => (
"admin" => (
"socket" => "/home/breezyduck/mysite.sock",
"check-local" => "disable",
)
),

)

alias.url = (
"/media/" => "/home/breezyduck/media/",
)

url.rewrite-once = (
  "^(/admin/.*)$" => "/admin.fcgi$1",
  "^(/media.*)$" => "$1",
  "^(/.*)$" => "/mysite.fcgi",
)
}

I started lighttpd using /etc/init.d/lighttpd start and it start
successfully (you can see this from one of the php sites www.semanticism.com).
I then started the fcgi process from manage.py using:

python manage.py runfcgi socket=/home/breezyduck/mysite.sock
pidfile=django.pid

and I checked in ps that it is indeed running.

However, when I attempt to go to http://breezyduck.com/admin/ it
returns:
500 - Internal Server Error

Please, any help is appreciated. Thank you!

JavaScript Frameworks...

[Kyle Hayes]

In an effort to better understand loosely what developer's think of
the JavaScript frameworks they use, I've created a short survey. It is
by no means a scientific representation of an overall census,
naturally. I hope to have a somewhat broad enough audience for this
short poll.

Please share your thoughts about your favorite JavaScript framework by
filling out the following survey:
http://bit.ly/jsfw

If you are interested in the compiled results, I will be posting it at
kylehayes.info/blog

Thanks in advance, I look forward to your feedback!

Port Number for Flatpages Sites

Never mind. Things are working fine. There was something wrong with my

Management commands not detected in all packages under a namespace?

[Kyle MacFarlane]

I have a bunch of packages under a company namespace, and inside
"company.__init__.py" in every package I have only the following:

__import__('pkg_resources').declare_namespace(__name__)

Everything works fine except when detecting management commands. It
will only detect commands in the first package in sys.path underneath
"company.*". Once it has checked one package in the namespace it does
not look inside any others.

So "company.first_app.management.commands.my_command.py" will be
detected but
"company.second_app.management.commands.another_command.py" will not.

I can effect which commands are detected and which are not by changing
the order of paths in sys.path.

Am I doing something wrong or is this a bug in Django?

This setuptools link may be useful if you don't understand what I mean
by a namespace package:

Pip apparently installs namespace packages differently and may work,
but I can't get it to work with zc.buildout and the recommended
gp.recipe.pip.

I cut down my buildout.cfg to be very simple and is basically a copy
of the example at http://pypi.python.org/pypi/gp.recipe.pip:


[buildout]
parts =
test1

[test1]
recipe = gp.recipe.pip
install = project_site
interpreter = python


But when I run buildout I get the following error:


Installing test1.
pip install
'import site' failed; use -v for traceback
Traceback (most recent call last):
  File "", line 1, in 
ImportError: No module named pip
While:
  Installing test1.

An internal error occured due to a bug in either zc.buildout or in a
recipe being used:

Testing feed generators doesn't load attribute templates?

[Kyle MacFarlane]

I extended django.utils.feedgenerator.Atom1Feed for my own needs and
am trying to write some tests for it. It works fine from rusnserver
and mod_wsgi.

Basically, when feeds are accessed from the testrunner I'm running
into these problems:

1) The item_title() and item_description() methods are never called,
but item_pubdate, item_link, etc are.

2) If I have no feed_title.html or feed_description.html templates
then both  and  will just be "Whatever object at
0xWHATEVER".

3) If I do have a feed_title.html and feed_description.html then
 will not even exist and  will be blank.

What am I doing wrong?

How can I apply ordering through a M2M join model?

[Kyle Fox]

I'm wondering if it's possible to apply ordering to a ManyToMany
relationship by using a `position` attribute on the join model.  A
classic example (photo gallery) is probably the best way to illustrate
this:

class Photo(models.Model):
image = models.ImageField(upload_to="photos")

class Gallery(models.Model):
name = models.CharField(max_length=100)
photos = models.ManyToManyField(Photo, through='GalleryPhoto')

class GalleryPhoto(models.Model):
gallery = models.ForeignKey(Gallery)
photo = models.ForeignKey(Photo)
position = models.IntegerField(default=0)

class Meta:
ordering = ('position',)

(Also at http://dpaste.com/hold/165618/)

I want to attach photos with a gallery, like this:

>>> GalleryPhoto.objects.create(photo=photo1, gallery=some_gallery, position=1)
>>> GalleryPhoto.objects.create(photo=photo2, gallery=some_gallery, position=2)

And then have the photos retrievable through the gallery *according to
the position attribute* on the GalleryPhoto, like so:

>>> gallery.photos.all()
[photo1, photo2]


The simplest fix would be to add create a `get_photos` method on the
Gallery which does a query for it's photos, but I'd rather stick to
straight Django models if at all possible.

Thanks!

Re: How can I apply ordering through a M2M join model?

[Kyle Fox]

The user needs to be able to manually position the photos in the
gallery (using drag and drop, for example).  A photo can exist in
multiple galleries, which is why the join model GalleryPhoto is
required (and this is where the position gets stored).

Developing a flexible CMS

[Kyle Fox]

I hope I can explain this well, because I've been wracking my poor
little brain trying to figure out how to do this :)

I'm trying to create a flexible CMS.  I want it to be easy for users
to create a Page, and attach all kinds of content ("components") to
that page.  These components would all be Model classes.  Here are two
simple examples of the components I had in mind:

class TextSnippet(models.Model):
body = models.TextField()

class Photo(models.Model):
image = models.ImageField(upload_to="photos")

The idea is that a user add an arbitrary number of these components to
a Page model.  A Page model is nothing more than a container to hold
components, and a URL associated with the Page, something like:

class Page(models.Model):
url = models.CharField( maxlength=100, unique=True,
validator_list=[validators.isAlphaNumericURL])

The problem is that I can't figure out a good way to associate
instances of TextSnippet and Photo with a page.  It's obviously a many-
to-many between the components and pages (a component like a photo can
be on many pages, and a page can have many components), but I also
need to store more information about that particular page-component
relationship, for example a IntegerField that specifies the
component's position on that page.  Here's what I've come up with so
far:

class PageComponent(models.Model):
page = models.ForeignKey(Page, related_name="components",
edit_inline=models.TABULAR)
content_type = models.ForeignKey(ContentType)
object_id = models.IntegerField(core=True)
position = models.IntegerField(default=0, blank=True)


It "works" not too bad.  Conceptually (from the shell), I think it
does what I want.  However, I'm having a HECK of a time getting the
Page form in the admin to work in an intuitive way.  When adding
components to a page, the user sees a drop-down list of content_types,
and has to enter an object_id.  It works for me because I know what to
put for the object_id, but a regular user wouldn't

I think this would require me to write a custom form class for adding
and editing a page, but with these relationships I really don't even
know where to begin :S

If anyone can provide advice (or just flat out tell me if I'm thinking
about this wrong), it would be much appreciated!

Thanks,
Kyle

Re: Blog engine

[Kyle Fox]

It's easy to write a "basic" blog in Django.  If that's all people
want, then great.  Something like that will work perfectly for the
majority of bloggers (who probably won't get that much readership
anyway)...

But all this talk about making a "full-featured" blog app in Django --
one that will really get noticed (and thus get django noticed): what
we need is a blog with *more features* that could actually begin to
compete with something like Wordpress**.

I mean stuff like Akismet, Flickr integration, delicious/magnolia
bookmarks, multi-author (with per-object permissions), importing from
Wordpress, statistics, easy web-based installation (NOT easy_install
but a wizard someone could follow, like the Wordpress install, lots of
customization, integration with pingback services, etc.

If that sounds like a lot, that's because it is.  To even be a blip on
the screen it will need this kind of stuff.  I also doubt the django-
admin will be sufficient for an application like this.

I know a lot of the stuff I've mentioned above has already been
hammered out by djangonauts -- I'm sure a snippet for almost every
feature has been posted on djangosnippets.org.  It's a matter of
bringing all those together into something that works out of the box,
rather than everyone patching together their own frankenstein.

** By the way, I know "competing with Wordpress" is nearly
impossible.  I'm just saying that to accomplish what it sounds like
people here are talking about, we need close to the same level of
functionality.

Re: Including view in a template

[Kyle Fox]

You might want to try writing an inclusion tag:
http://www.djangoproject.com/documentation/templates_python/#inclusion-tags

They are much simpler to write than template tags, and more "designer
friendly."  They let you write a separate template that gets rendered
inside of another template (similar to how partials worked in Rails).

So for example you could write a template tag called 'list_users', and
create a template called 'list_users.html'.  Then in
frontpage_template.html you could add something like {% list_users %}
and it will render the list_users.html template.

I work primarily with designers who write the actual templates, so
it's much more intuitive for them to simply drop in something like {%
main_menu %} whenever they want to show the site nav, and then just
edit main_menu.html when they want to modify the markup/design.

In need of a more flexible URL routing scheme...

[Kyle Fox]

I've been having a hard time figuring out how to solve this problem:

We're building *another* django blogging app, but we want the app to
support multiple blogs on the same site, ideally by having each Blog
"mounted" on it's own URL, ie: "/politics/" is a Blog, "/tumbles/" is
another Blog, etc.

To accomplish this, I have a `Blog` model which looks roughly
something like this:

class Blog(models.Model):
site = models.ForeignKey(Site)
title = models.CharField(max_length=500)
url = models.SlugField('URL', prepopulate_from=("title",),
blank=True)

urls.py then contains lines like this:
(r'^(?P[-\w]+)/categories/',
include('glyph.apps.categories.urls')),

That way we can create new Blogs, and have the URLs be generic enough
to handle any blog's url.  The problem is that we also want to allow a
Blog to have a blank URL, i.e. have it mounted on the root of the
domain.  That way "example.com/categories/" would route to
`glyph.apps.categories.urls', and execute all the views using the Blog
with an empty URL field.  I'm really stuck figuring out how to do
this...

I would greatly appreciate any advice!  I'm really not sure how to do
this, but what I have so far sure doesn't feel like an elegant
solution :(

(For reference, the entirety of the code is at 
http://code.google.com/p/glyph-blog/.
I know it's messy, I'm working on making it better :)

Re: wordpress hooks and actions system in django?

[Kyle Fox]

The part that I'm struggling to wrap my head around is how to make
plugins "installable".

I think one of the reasons Wordpress's plugin framework is so
successful is how easy it is to manage your plugins: install /
uninstall buttons on a page means the user doesn't have to write any
glue code or even do anything from the command line.

I guess you could have an empty 'plugins' app somewhere, and simply
drop py files into it for each plugin.  What are your guys' thoughts
on how to accomplish this?

Re: Suggestions for Django Presentation

[Kyle Fox]

Filters are unbelievably helpful when you have different people doing
markup and development.

The 'pluralize' filter, for example (as well as the 'humanize'
collection), has saved us developers from having to write templae-side
code to figure out if there should be an 's' at the end of a noun.
This shouldn't be a programmer's job: it's a presentation issue and
should be dealt with by the XHTML authors.  Filters lets this happen.

The concept is very simple to grasp, easy to demonstrate, and
EXTREMELY useful!

By the way, good luck with the presentation!

Do you mean this feature isn't yet in django?  I haven't found

If it's in the trunk, do you know where I can find more info on it?

Re: Need some help with Amazon S3

[Kyle Fox]

1)  We found S3 to be a bit slow, both upstream and down.  Upstream is
slow largely because of the SOAP overhead (from what I understand),
and we were sending lots of data (about 5 resized images for each
image uploaded to django).  Downstream, well, not much you can do
about that, regardless of how you set up you models.  We simply stored
the image's S3 key in the database, and used that when constructing
get_absolute_url().

2) I'm not sure you can do this.  When you say you want to have a
connection with the service, are you referring to a connection using
the S3 python library?  I'm not sure how you would create a global,
persistant connection to S3, which is what I assume you want.  We
simple made a wrapper class around S3, and added a add_to_bucket()
function to our user's profile model that used the S3 wrapper class.
Again, this seemed reasonably fast, the bottleneck was not around
managing the connection to S3, but the actual upload to S3 itself.

Moving Images to Amazon S3

[Kyle Fox]

I'm absolutely stuck on this.  This question might be more python than
django related, but I figured because it deals with Amazon S3, someone
here may know how to handle it.

Here's what needs to happen:
1.  A user uploads an image (part of a Model we have)
2.  Create a 100x100 thumbnail using PIL
3.  Move the thumbnail to Amazon S3

Step 3 is the tricky part for me. I can't figure out how to do it,
other than first temporarily saving the in-memory thumbnail to the
filesystem, re-reading the file, moving the raw data to S3, and then
deleting the temporary thumbnail file:

# thumb is an already thumbnailed Image instance, in memory
thumb.save( temp_path, "JPEG")
raw = open( temp_path ).read()
# code to move 'raw' to S3
os.remove( temp_path )

This is a pretty heavy way of doing it, and I'm desperate to find a
better way of doing it but am absolutely out of ideas...

The S3 API requires the file data to be in the format the
open(myfile).read() returns (whatever that is).

Is there a way to get the same data from an in-memory Image instance,
so I don't need to save/re-read/delete each thumbnail file?

Re: Moving Images to Amazon S3

[Kyle Fox]

I think my question wasn't clear:  we're having NO problem putting
files on S3, that's dead simple (ie what Holovaty blogged about).

What we need to do is take an *in-memory Image* and put it directly
onto S3.  We need a way to convert a PIL Image instance into a format
S3 can accept WITHOUT having to first save the Image to the file-
system.  S3 accepts the kind of string that gets returned from
open(afile).read()

I was trying to wrap the result of img.tostring() in the StringIO

Re: Django deployment à lá Capistrano

[Kyle Fox]

I really don't see a need for a huge project to accomplish the goals
you've outlined:

0) Checking in the local source changes if they have not already been
checked in (optional).
1) Logging into the deployment target.
2) Checking out the latest source.
3) Modifying the production database as necessary.
4) Making appropriate changes to settings.py.
5) Running tests
6) Restarting the server
7) Cleaning up and logging out.

We have a little shell script that does most of this stuff just fine,
in about 10 lines.

What makes Capistrano handy is the ability to *transparently* deploy
your application across many different machines, and specify roles for
each machine which respond to different tasks.

I am also *extremely* cautious about having scripts modify a
production database with Django.  AFAIK, there is currently no
standard way of keeping track of schema changes in Django.  (This is
more feasible in Rails because of migrations).  Furthermore, one of
the killer features of Capistrano is the ability to completely
rollback your entire application to a previous point in time (db
schema, data and code base) -- but without a standard schema-evolution
tool in Django, how will Djangostrano be able to track & version
changes?

I would love to see a tool that makes the HARD deployment tasks easy.
I suppose what you've outlined is a start, but maybe we'd be better
off to work towards a set of individual tools that can be integrated
right into django (like schema evolution/versioning, etc) prior to
trying to automate these tasks.

How to use SplitDateTimeWidget (getting TypeError)

[Kyle Fox]

I'm trying to use a SplitDateTimeWidget for a forms.DateTimeField
field, but keep getting TypeError: "expected string or buffer"

The traceback leads to `strptime.py`, which has `found =
format_regex.match(data_string) `.  The local variables are:

data_string = [u'2007-09-29', u'11:05:59.898833']
format = u'%Y-%m-%d %H:%M:%S

It looks like the SplitDateTimeWidget is returning an array of [date,
time] strings, when it should be returning a single string.

Does anyone know how to do this?  Am I using the SplitDateTimeWidget
incorrectly?

Thanks,
Kyle.

Re: Design Question : model needs in model or view

[Kyle Fox]

I'd probably put it in the model.

Putting it in the view means if you ever create an instance of that
model elsewhere, you'll need to duplicate the code for creating the
related model.  Not very DRY :)

Why does django throw TypeError when sending requests through Apache WSGI?

Started a new project after not using Django for roughly two years, works

I am not using either of those, I think. The only place I explicitly load

os.environ[‘DJANGO_SETTINGS_MODULE’] = ‘travel data.settings'

Getting InspectDB to work with postgres

[Kyle Wan]

Hi,

I'm new to Django, and I'm struggling to get inspectdb to populate postgres 
models as json, hstore, or array objects. I have put 
`django.contrib.postgres` under the INSTALLED_APPS and I have psycopg2 
installed. I have set my engine to be postgresql and am able to use the 
makemigration and migrate CLI.

Do I need to do anything extra to get this working? I know inspectdb may 
not work because it is guessing, but it seems like this is a solved issue 
in terms of json, hstore, and array for postgres as many people have asked 
about this issue years past. I am using version 4.1.7 of django.

I'm trying to make an automated script for creating the migration with 
inspectdb -> makemigration -> migrate, but there is no easy way for 
detecting what type the inspectdb guessed as TextField.

Thanks!

Re: SMTPDataError with mail_admins, no problem with send_mail

[Kyle Gong]

This might be 3 years too late, but I had this same problem and the issue 
was that my ADMINS setting wasn't a list or tuple:

ADMINS = (
('Admin', 't...@test.com')
)

changed it to the following and mail_admins worked:

ADMINS = (
('Admin', 't...@test.com'),
)

How to run all tests in INSTALLED_APPS with the new test runner 1.6?

[Kyle MacFarlane]

With the new test runner in 1.6 it only seems to be running tests under my 
project and ignoring all tests in dependent apps listed in INSTALLED_APPS.

If I try to specify another app to test by doing something like "django 
test a_dependency" I get an exception from Python's unittest saying "Path 
must be within the project" (all my dependencies are installed system wide 
or in a shared buildout folder in my user dir).

The only tests outside of my project I seem to be able to run are Django's 
itself via "django test django".

How can I get the new test runner to discover and run all tests in 
INSTALLED_APPS? As far as I can tell the new test runner only supports 
tests located under the cwd which is not very useful for me since my 
projects tend to just amalgamate smaller apps located elsewhere.

Hello,

I am having the same problem while working through the tutorial. have

Need help with tutorial

[Kyle Latham]

I'm trying to work my way through the tutorial 1 but am getting stuck.
I am using python 2.7 and am using SQLite3 like the tutorial
recommended for beginners

I am at the step where I am changing the models.py file to add the
_unicode_ methods to display the Poll Object

I believe I have the NAME in the settings.py file set up correctly. I
first set did
'NAME': 'database.db',
to create my database file, then I changed it to the path to that
file.

Anyways, after I modified the models.py file to display the
question...
>>> Poll.objects.all()
[]

I am still getting

>>> Poll.objects.all()
[]

as the output.

Any help would be greatly appreciated.

Thanks,

Kyle

Re: Need help with tutorial

[Kyle Latham]

I understand your frustration. I'm sorry for not posting my code with
my first post.

my settings.py file (only up to the part I changed) is below:

# Django settings for mysite project.

DEBUG = True
TEMPLATE_DEBUG = DEBUG

ADMINS = (
# ('Name', 'n...@email.com'),
)

MANAGERS = ADMINS

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3', # Add
'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
'NAME': 'C:/Django/django/bin/mysite/
database.db',  # Or path to database file if using
sqlite3.
'USER': '',  # Not used with sqlite3.
'PASSWORD': '',  # Not used with sqlite3.
'HOST': '',  # Set to empty string for
localhost. Not used with sqlite3.
'PORT': '',  # Set to empty string for
default. Not used with sqlite3.
}
}


My models.py file is:

from django.db import models
import datetime

# Create your models here.
class Poll(models.Model):
question = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')

def _unicode_(self):
return self.question

def was_published_today(self):
return self.pub_date.date() == datetime.date.today()

class Choice(models.Model):
poll = models.ForeignKey(Poll)
choice = models.CharField(max_length=200)
votes = models.IntegerField()

def _unicode_(self):
return self.choice



Thanks for your help.

Django won't send 500 or 404 emails, but django.core.mail.EmailMessage and django.utils.log.AdminEmailHandler work

[Kyle Gong]

For some reason, I can't get my server to send 500 or 404 emails.  I
am set up to send email through gmail, and it is working properly when
I send error emails through a logger set up using
django.utils.log.AdminEmailHandler, and also when I send mail using
django.core.mail.EmailMessage.

I have DEBUG = False and SEND_BROKEN_LINK_EMAILS = True.

The server is a linode running Ubuntu 10.04, Django 1.3 and Python
2.6.5.

Any idea where I could look to track down the problem?

Question about Displaying a Table

[Kyle Latham]

Hello,

I am pretty new to Django and Python.

I'm wanting to create a Django app that displays different tables in
my MySQL database, and the user can search through the tables for info
they want.

I haven't written any code yet, I'm doing research on the approach I
have to take.  Is the only way I am able to display a table from the
MySQL database in Django by creating a template and importing the data
to the template? Is there a another/better approach towards displaying
a MySQL table in the Django app?

Thank you,

Kyle

ImportError: No module named site

[Kyle Latham]

I searched this group for that error, and browsed through several
pages and dozens of posts...but none of them helped me solve my error.

Yesterday I had my server up and running, and I left it running
overnight. I do not remember changing anything in any of my .py files,
but when I shut down my server to restart it, I was getting an error:

"Import Error: No module named site"

I have no idea what is going wrong, but here is all my code thus far
(I'm following the tutorial to create my own app that will display
various material measurements)

---
models.py
---
from django.db import models

# Create your models here.
class adhesive(models.Model):
measurement_id = models.CharField(max_length = 200)
material_id = models.CharField(max_length = 200)
program_name = models.CharField(max_length = 200)
date = models.DateField()
measurement_method = models.CharField(max_length = 30)
frequency_low = models.IntegerField()
frequency_high = models.IntegerField()

class ceramic(models.Model):
measurement_id = models.CharField(max_length = 200)
material_id = models.CharField(max_length = 200)
program_name = models.CharField(max_length = 200)
date = models.DateField()
measurement_method = models.CharField(max_length = 30)
frequency_low = models.IntegerField()
frequency_high = models.IntegerField()

class composite(models.Model):
measurement_id = models.CharField(max_length = 200)
material_id = models.CharField(max_length = 200)
program_name = models.CharField(max_length = 200)
date = models.DateField()
measurement_method = models.CharField(max_length = 30)
frequency_low = models.IntegerField()
frequency_high = models.IntegerField()

Getting list of user groups

[Kyle Adams]

I'm trying to get a list of the user groups available in a system. I have 
groups set up, but how do I, on some request, get a list of the names of 
each of the groups in my system?

For some context, I'm working on an analytics dashboard, and part of what I 
want to be able to do is look at the data for certain groups, perhaps staff 
and non-staff. To do this, I want to be able to ask Django for the list of 
groups first, so the user can choose a group from there, and then later 
will get a list of all users in that group, so I can look only at their 
data.

Re: Getting list of user groups

[Kyle Adams]

Thanks for your help, Russ. I'm planning to expose the user to the names of 
the groups using a drop list on my site. They'll choose a group, then our 
site will get the list of users in that group from Django, and then send a 
query to our database to get the data for that group of users.

Re: Getting list of user groups

[Kyle Adams]

One issue I'm still having is actually getting the list of group names. I'm 
trying to use the line

groups = Group.objects.value_list('name', flat=True)

but I'm getting an error that reads 

'GroupManager' object has no attribute 'value_list'


Any idea about this?

After some more research, turns out it is "values_list" instead of

Re: My class communication design problem.

[Kyle Connors]

I believe what you're looking for is an initial value. In __init__ the 
following would achieve this:

self.fields['exercise_field'].initial = self.getRandomText(self.language, 
self.dictionary)

tutorial site refers to a module which does not exist

[Kyle Foley]

I'm trying to teach myself Django on this site:

https://docs.djangoproject.com/en/1.11/intro/tutorial02/

If you look at this sentence:

To include the app in our project, we need to add a reference to its 
configuration class in the INSTALLED_APPS 

 setting. 
The PollsConfig class is in the polls/apps.py file, so its dotted path is 
'polls.apps.PollsConfig'.

They haven't told me what the pollsconfig class consists in, nor have they 
told me to build the apps.py module.  When I run the command line

python manage.py makemigrations polls

ModuleNotFoundError: No module named 'polls.apps.PollsConfig'; 'polls.apps' 
is not a package


So what am I supposed to put in that module?

Re: tutorial site refers to a module which does not exist

[Kyle Foley]

But if you look at the previous page where the apps.py is created

https://docs.djangoproject.com/en/1.11/intro/tutorial01/

you'll see that in no case do they ask you to put anything in the apps.py
It's blank, there's no pollsconfig in that file.

migrations/
__init__.py

tests.py
views.py


but instead the apps.py did not create

Re: tutorial site refers to a module which does not exist

[Kyle Foley]

I called a consultant and he told me to write the following code

INSTALLED_APPS = (
'polls',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',


and that solved the issue.  but i'm a little confused as to why the apps.py 
module is not being created.

tutorial site not working

[Kyle Foley]

At this site

https://docs.djangoproject.com/en/1.11/intro/tutorial02/

towards the end I input the following:

>>> q.was_published_recently()


and I got the following error:


Traceback (most recent call last):

  File 
"/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/django/core/management/commands/shell.py",
 line 69, in handle

self.run_shell(shell=options['interface'])

  File 
"/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/django/core/management/commands/shell.py",
 line 61, in run_shell

ImportError


During handling of the above exception, another exception occurred:


Traceback (most recent call last):

  File "", line 1, in 

AttributeError: 'Question' object has no attribute 'was_published_recently'

>>> 


It's also not very clear from that site how they want the models.py file to 
look. Right now I have:


import datetime

from django.db import models
from django.utils.encoding import python_2_unicode_compatible
from django.utils import timezone

@python_2_unicode_compatible  # only if you need to support Python 2
class Question(models.Model):
# ...
def __str__(self):
return self.question_text

def was_published_recently(self):
return self.pub_date >= timezone.now() - datetime.timedelta(days=1)

datetime.timedelta(days=1)

@python_2_unicode_compatible  # only if you need to support Python 2
class Choice(models.Model):
# ...
def __str__(self):
return self.choice_text


But I'm not sure that's right.

Let me also show what I have placed in the terminal

I also don't understand why I am outputting:

Re: Error running Django tutorial

[kyle D]

I'm using Django for a class, and came across this thread and thought I'd 
post what fixed it for me in case someone else has the same issue I did.

Makes sure your mysite/urls.py is the one that has the urlpatterns[] with 
the path to your polls and not the mysite/polls/urls.py.

This one:
urlpatterns = [
path('polls/', include('polls.urls')),
path('admin/', admin.site.urls),
]

 
Not this one:
app_name = 'polls'
urlpatterns = [
# ex: /polls/

Re: Conseil et Guide

Salut mon ami,

Les Frameworks facilitent la création de contenu avec un gain de temps.
Personnellement j'aime Django pour sa facilité et le fait qu'il est écrit
en python et si t'es plutôt php je te conseille Laravel que symphony

Zero Downtime Field Type Changes

['Kyle Mulka' via Django users]

Hi there,

Wondering if there's any tool out there to make a zero downtime field type 
change easier. I want to change a django model field from one type to 
another, and the format of the field in the database is slightly different.

I've come up with a process I think will work, but it will be rather 
tedious if done manually. Wondering if there's a more automated approach or 
other tools out there already. I'd like to come up with a general solution 
for use in the future, but right now trying to tackle converting UUIDField 
from django-extensions to the built in django version.
https://github.com/django-extensions/django-extensions/issues/647

I was thinking about maybe using a custom field that supports both types, 
but not exactly sure how to write a custom field that would do that.

If it helps, the manual process I'm thinking about kind of goes as follows:

# existing model:
class Model:
field = OldField()

# add field_old with OldField type
# when updating or adding rows start writing to both fields
# copy data from field to field_old
class Model:
field = OldField()
field_old = OldField()

# stop using field, only use field_old
# remove field
class Model:
field_old = OldField()

# create field with new type
# when updating or adding rows start writing to both fields in their 
respective formats
# copy data from field_old in old format to field in new format
class Model:
field = NewField()
field_old = OldField()

# stop using field_old
# remove field_old
class Model:
field = NewField()

Thanks for your help!

Prefetch and custom managers

['Kyle Mulka' via Django users]

Hello,

I'm having an issue with trying to use prefetch and custom managers 
together. They seem to be interacting in a weird way. Wondering if I'm 
doing something wrong.

I've set up a test django project which demonstrates the issue here:
https://github.com/mulka/django_prefetch_manager_bug

These two tests are coming back with different results:
https://github.com/mulka/django_prefetch_manager_bug/blob/master/review_site/tests.py

Here's the models file:
https://github.com/mulka/django_prefetch_manager_bug/blob/master/review_site/models.py

Thanks in advance for your help!

-Kyle

Custom Django Admin Pages

['Kyle Mulka' via Django users]

Hi there,

It seems like Django Admin is designed to work with Django models. But, I'm 
wondering what the best way is to create custom admin pages that don't 
revolve around Django models. Like, maybe there's a third party API that I 
want admins to be able to call from the Django admin. What's the best way 
to get custom pages to show up and render in the Django admin?

Thanks,

Kyle
