Re: problem with Django

Check the file and directory permissions like suggested when you were
first trying to setup your site, this time looking at any new files
and directories you have added within your site area. They should have
permissions so they are readable to Apache.

Re: problem with Django

[Graham Dumpleton]

Go and read the mod_python documentation again. In particular:

"""An example might make this clearer. Suppose you have some
applications under /usr/local/django-apps/ (for example, /usr/local/
django-apps/weblog/ and so forth), your settings file is at /var/www/
mysite/settings.py and you have specified DJANGO_SETTINGS_MODULE as in
the above example. In this case, you would need to write your
PythonPath directive as:

PythonPath "['/usr/local/django-apps/', '/var/www'] + sys.path"

With this path, import weblog and import mysite.settings will both
work. If you had import blogroll in your code somewhere and blogroll
lived under the weblog/ directory, you would also need to add /usr/
local/django-apps/weblog/ to your PythonPath. Remember: the parent
directories of anything you import directly must be on the Python
path."""

What the last paragraph is saying is that because of the way that you
are using imports and or urls.py, you need to add the site directory
as well as its parent to PythonPath.

Thus:

  PythonPath "['/home/priya','/home/priya/mysite'] + sys.path]

This is the preferred way if using mod_python and avoids needing to
symlink stuff into your Python site-packages directory.

webhostingbuzz, anyone tried

[[EMAIL PROTECTED]]

Hi guys.
These guys seem to have very tempting packages. They say they support
django. What I'd like to know is what kind of support? Do I have to
install it on my home folder, or is it preinstalled on their servers?
Second thing I wanted to ask about, is the speed. My current account
goes really slow, and it has only one flatpage to handle. How good it
webhostingbuzz on that issue?
Thanks in advance
Yair

Hi Kenneth,

   The page is not displaying any error message but it says

I ran into this problem a while ago while doing a hobby project. At
the time I solved it by adding something like the following (using
your example names) to models/__init__.py:

from app.models.isp import *

and then in isp.py:

class Foo(models.Model)
some_field = models.CharField(max_length=200)
class Meta:
app_label = 'app'

This was a while ago, so there may be a better way to do it now, but I
just fired up that app with django r6602 and manage.py sql app spat
out sql that looked OK.

users = User.objects.filter(id__in=[x.id for x in u]).values()

Splitting models.py into a package

[Darryl Ross]

Hey All,

I have an app that has quite a few models in it, so I am trying to split
it out into a package, but when I do the models do not show up in the
admin interface and running 'manage.py sqlall app' does not show any SQL
statements for creating the tables.

Is there a trick to doing this?

The steps that I took are:
 $ mkdir app/models
 $ touch app/models/__init__.py
 $ mv app/models.py app/models/isp.py

From my views I can do 'from project.app.models.isp import ISP' and it
all works, but it would seem that any of the django tools can't see
them. I'm not so much worried about the admin app, but manage.py not
being able to create the tables or permission is a problem.

According to James Bennett on his blog at http://tinyurl.com/3d39p4 this
should work?

Erm... no. The contributions of our little friend from this morning
were removed when I manually deleted his posts and banned his account
from posting in the future.

Google's spam catching is good, but it receives a lot of assistance
from the list moderators. That assistance takes a lot of effort,
because the spam-purging interface on Google Groups is utterly painful
- removing a single post takes 5 clicks and 3 page loads; assuming you
already banning an account requires you to manually transcribe an
email address/username and search for the culprit, plus an additional
3 clicks (assuming you already have the user management tools open).
On top of that, if you try to purge too many messages in a row, Google
blocks the request on the basis that you might be a bot, and presents
a captcha.

Re: Session variables without a database

[@@]

Configuring the session engine

*New in development version*.

By default, Django stores sessions in your database (using the model
django.contrib.sessions.models.Session). Though this is convenient, in some
setups it's faster to store session data elsewhere, so Django can be
configured to store session data on your filesystem or in your cache.
 Using file-based sessions

To use file-based sessions, set the SESSION_ENGINE setting to "
django.contrib.sessions.backends.file".

You might also want to set the SESSION_FILE_PATH setting (which defaults to
/tmp) to control where Django stores session files. Be sure to check that
your Web server has permissions to read and write to this location.

Just to follow up, I mentioned Google's excellent filtering and  
banning regime. My email inbox has 8 messages (4 unique with  
duplicates) from a certain someone that were posted this morning in  
the developers group. None of those messages appear in Google's online  
web site. Like any neighborhood with a graffiti problem, I think  
Google recognizes that users who report spam in their groups are more  
likely to get the "cops" to come around and help clean up, so report  
spammers to Google when you get a chance.

For those of you who would like to read messages and not have to worry  
about the boss wondering what you're looking at, reading Google Groups  
online may be a good option.

Session variables without a database

[[EMAIL PROTECTED]]

I need to put together a small site for some demos...I don't need a
database as I'm getting my data via some API calls,  but wanted to use
Django templates.   I had wanted to store this data in a session
variable ( the API calls can take a while)... I thought I remembered
reading somewhere it wasn't possible to use session variables w/out
using a Database with Django.  Anyone have any work arounds for
this?

Thanks for any info.

I usually go to the Google Groups web site for this and the dev group.

how to set mysql collation in django?

[Anton Daneika]

hello all,

i need something like TEST_DATABASE_COLLATION, but in a normal django code
-- not in the tests.

i am running the same script in two environments: as a part of unit test and
on it's own and get different results. i suspect the reason for getting
different results is django's way of setting collations. my unit test fails
when TEST_DATABASE_COLLATION option is set to utf8_unicode_ci, but runs ok
if it's utf8_swedish_ci, however i do not know the way to set the collation
for the application database. it seems strange that this option is only
available for testing purposes. does anyone know how do i set different
collation?

the rest of this letter is for the curious ones.
here's the example of the unit test script:

class UnknownErrorTestCase(TestCase):
fixtures = ['collation_error_db_state.json']
def testUnknownError(self):
lang = Language.objects.get(pk='sv')
movie = Movie.objects.get(pk=10)
movie.keywords.create(word='män', language=lang)

this test passes if TEST_DATABASE_COLLATION is utf8_swedish_ci and fails if
it's utf8_unicode_ci (throws _mysql_exceptions.IntegrityError). the Keyword
model has uniqueness constraint: unique_together = (("word", "language"),).
the fixture loads a Keyword object whose "word" property is "man". this
happens because 'man' == 'män' if utf8_unicode_ci collation is used, so
trying to insert a new Keyword throws integrity error. the problem arises
when i try to ran these three lines of code outside the unit test script
where the collation is not read from the TEST_DATABASE_COLLATION.

Hi!

Has there been any more progress toward getting the multiple database
branch merged into trunk?  I, among many others, would really like to
be able to use the newer features of django and access multiple

Thanks!

Just launched a pretty big new Django site @ revver.com

[[EMAIL PROTECTED]]

Hi all - I don't think i've actually posted to the list, but reading
the archives has really helped make my Django development process go
smoothly, so I owe you all a debt of gratitude for various bits of
knowledge gleaned during the development process of my company's web
app at http://revver.com . We replaced a Rails web app with a more
featureful (and far, far more performant) Django app, and couldn't be
happier with the framework.  Hopefully we'll release some of the
libraries we wrote soon (specifically a caching proxy for our XMLRPC
API), and that way I'll be able to give some of the knowledge back :)

Any clean_FIELDNAME methods are called as part of the validation 
triggered when you call is_valid [1]. I assumed you were creating a 
custom form before - in your case, you'll want to use the 'form' 
argument [2] to pass in a BaseForm which implements any extra 
functionality you need:

forms
-
class ClubBaseForm(forms.BaseForm):
 def clean_name(self):
 slug = slugify(self.cleaned_data['name'])
 if Club.objects.filter(slug=slug).count():
 raise forms.ValidationError(u'Club is already in database')
 return self.cleaned_data['name']

view

ClubForm = form_for_model(Club, form=ClubBaseForm)
if request.method == 'POST':
  form = ClubForm(data=request.POST)
  if form.is_valid():
  # For DRY's sake, I'm assuming the slug is set by an
  # overriden save() method in the Club model.
  club = form.save()
  return HttpResponseRedirect(club.get_absolute_url())
else:
  form = ClubForm()

I've found the trick with newforms is that if you can get the form to do 
as much work as possible for you validation-wise, displaying and 
redisplaying with errors is a piece of cake, no matter how complex the form.

Sounds like some sort of user access problem - like the www-data

Thanks Jonathan... yeah, I smelled that smell. I'm not quite following
you, though. Where is clean_name() called? I think I may be confused
because I have ClubFormClass = nforms.form_for_model(Club)  rather
than def ClubForm(forms.Form):

I'd implement it as a clean_fieldname method. The fact that in the above 
you're having to mess around with errors dictionary manually for 
something this simple is a bad smell to watch out for.

form


def ClubForm(forms.Form):
 name = forms.CharField(...)

 def clean_name(self):
slug = slugify(self.cleaned_data['name'])
 if Club.objects.filter(slug=slug).count():
 raise forms.ValidationError(u'Club is already in database')

 form = ClubForm(data=request.POST)
 if form.is_valid():
 club = form.save() # Do the slugify() in your save method
 return HttpResponseRedirect(club.get_absolute_url())

Re: YAFU: Yet Another File Upload app...

[Eugene Morozov]

Hello,
Thanks for your contribution. There's a similar functionality in
Django Trac #2070 and #4165.

#2070 contains patch with an implementation of streaming file uploads.
This seems to be working.
#4165 contains middleware and javascript that implement file upload
progress monitoring for the Django admin interface. Unfortunately,
this code is very unreliable, especially Javascript. Sorry guys,
whoever wrote the Javascript part, but it is a real mess. I've
implemented a much nice version using jQuery progress bar and jQuery
modal windows, but it's a part of commercial project so I'm afraid I
cannot share. Currently my Javascript upload monitor it uses
middleware from #4165 but I plan to replace it with my own version as
this middleware sometimes report bogus data.

So, it is possible to implement file upload progress monitor without
external CGI script and IFRAMEs. Just apply #2070 (it looks more
polished than patches from #4165), implement simple middleware that
will track file uploading progress, and a tiny Javascript that will
ask middleware about progress using XMLHttpRequest.

There's no "official" way to do this yet, but I just published an

FileField and filenames. Hopefully this helps with your question as

Wow, that was quick, 3min response!  Thanks.

Yea, thats what I was thinking.  Trying to be very DRY.

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 :)

Design Question : model needs in model or view

[John M]

I have a model that has a 1-1 model attached to it.  This attached
model has mostly default values that will be referenced later.

My question is, should I put the creation of the 1-1 model in the
SAVE() method of the main object, or in the view where it's created?
seems like putting it in the SAVE() method would keep the design
isolated from the other areas.

Thanks for your help.

John

Re: form_for_instance and form argument, empty form?

[Marty Alchin]

Sorry folks, there was a bit of confusion with this thread, having
started out on django-developers. GMail didn't seem to think I really
wanted it to go to django-users instead, so I only just noticed it had
continued on django-developers. If you're interested in what's going

Checking for duplicate with newforms

[[EMAIL PROTECTED]]

I have a public-facing form where registered users can submit clubs.
Later, I access the data by slug, using a generic object_detail view.

My problem is that someone can input a club that's already there.
Besides polluting the database, it breaks when they try to access the
club's page (GET returns 2).

So, how can I have newforms check for a dupe before saving the form
and (hopefully) return an error message if there is a dupe? Here's the
newforms part I have:

if request.method == 'POST':
submission = request.POST.copy()
submission['slug'] = slugify(submission['name'])
form = ClubFormClass(submission)
if form.is_valid():
form.save()
 return HttpResponseRedirect('/thankyou/')
  else:
 form = ClubFormClass()

Just as I suspected. You need quotes around
'django.views.generic.create_update.create_object' here. It's looking
for an object named 'django' which isn't currently defined in this
module.

context_instance needs documenting on the same page as render_to_response?

[AndyB]

Just read James Bennett's excellent article here:
http://www.b-list.org/weblog/2007/nov/01/django-tips-template-loading-and-rendering/

In it he mentioned request_context and the context_instance parameter
to render_to_response and mentions that many people he talks to don't
know of it's existence.

Maybe the reason a lot of people don't know about the context_instance
is that it isn't mentioned here: 
http://www.djangoproject.com/weblog/2005/sep/24/newshortcuts/
or here: http://www.djangoproject.com/documentation/shortcuts/

and they are the top two results in Google for 'render_to_response'

Although it is mentioned here:
http://www.djangoproject.com/documentation/templates_python/#subclassing-context-requestcontext

This page doesn't even show up on the first page of results so it
isn't surprising people miss it. Worth adding a mention to the docs?

It's not much: 



from django.conf.urls.defaults import *
from models import *

info_dict = { "queryset": BlogEntry.objects.all().order_by("-creationDate"), }

urlpatterns = patterns("",
(r'^$', 'django.views.generic.list_detail.object_list', dict(info_dict,

(r'^page(?P[0-9]+)/$', 'django.views.generic.list_detail.object_list',

(r"^newComment/$", django.views.generic.create_update.create_object,

YAFU: Yet Another File Upload app...

[Dustin Lang]

Hi,

It didn't seem like any of the current Django file upload apps provided exactly 
the functionality I needed, so I hacked my own.  If the community is 
interested, I can try to polish it a bit and contribute it.

We deal with large uploads - up to hundreds of megabytes - so I wanted the 
following:

-the server should not keep the whole file in memory while the upload is 
progressing: it should stream to disk

-the server shouldn't have to copy the streamed data: it should only write the 
uploaded file once

-the user must get some feedback (a progress meter, or whatever) while the 
upload is progressing


I wrote some code that accomplishes this.  You can see an ugly demo at:
http://oven.cosmo.fas.nyu.edu:/upload-demo/

It works as follows:

-There is a python CGI program that accepts the upload.  It's not a Django view 
because it needs to stream the input as it comes in from the network; it runs 
as a normal mod_python handler.

-This CGI program parses the multipart/form-data input, looking for an 
"upload_id" field (which tells it which temp file to write the uploaded file 
to), and then looks for the file data itself and streams that to disk.  At the 
end of the upload, it produces a dictionary of the "normal" form fields and an 
object representing the uploaded file.

-We have a "main" form with several fields, and within that HTML page there are 
two IFRAMEs.  The first one contains an "upload" form: it requests a form which 
has a hidden "upload_id" field and a file input element (and a hidden submit 
button).  The second IFRAME contains an (initially hidden) upload progress 
meter.

-If the user submits the "upload" form (by hitting ENTER in the file input 
dialog), some Javascript gets triggered which displays the upload progress 
meter.  (The upload progress meter is a snazzy little AJAX dealie - quite nice 
but its CSS needs some attention).  If the file is empty or some other error 
occurs, the progress meter shows an error message.

-When the file upload starts, the CGI writes "Upload in progress..." and when 
if it finishes successfully, it writes a hidden  element.  Some Javascript 
notices that the upload form's IFRAME finished loading, and it looks for that 
 to ensure that the upload was successful.  If so, it grabs the 
"upload_id", saves it in a hidden field in the main form, and submits the main 
form.

-The main form goes to a normal Django view, and it can use the "upload_id" to 
pull a reference to the file out of a database.


I know it sounds overly complicated, but it seemed to be necessary to achieve 
the user experience and server-side requirements I had.

Before it's ready for prime-time, it will need some fixes:

-the form-multipart parsing is currently hacky; the RFC should get translated 
into regular expressions

-the upload form handler currently doesn't really do anything with the other 
form fields - it should store them in a database.

-there's not a lot of checking of upload_id values - one could easily add some 
rules that only upload_ids that have been generated by the server can be 
uploaded; and that it's invalid to try to re-upload a file; or that only 
authenticated users are allowed to upload files.

-I'm new to python and Django, so I'm sure there is a lot of polishing that 
could be done.

-I tried to work out a solution that didn't require two IFRAMES (one for the 
file form, one for the progress meter), but couldn't get it to work.


Anyway, let me know if you're interested in this code and I'll bundle it up if 
anyone is.

Cheers,
dstn.

Actually, it would help if you would paste here your
AUTH_PROFILE_MODULE  setting as well as your profile model class.
Also, what Django app name does this profile model live under?

This just means that django is not in your PYTHONPATH. If your server
is already running the original Django app, it means that Django is
installed. Take a look at the installation documentation to learn more
about setting up your PYTHONPATH and other environment.

http://www.djangoproject.com/documentation/install/

Also, as an aside, try using some kind of source control (subversion,
for example) so that you avoid changing your production source code
directly on your production server. A better way to do this is to
change things on your development/test environment, test it there,
commit your stable changes to a source control repository and then
grab and install them on your production server from the repository.

If you post the whole contents of the 'xgm.Blog.urls' module, it might
be more clear what's going on. Use http://dpaste.com/ if it's too

Your best bet for progress is to check my blog[1] where I plan to
write all about it when I've updated it. If you don't care about the
rest of my work, just check out the 'modular' tag.[2] You can check
the repository as well, if you like, but it'll probably be tough to
figure out what's going on.

Actually, you could use the flatpages model for this if not the whole
Flatpages application. Here's how:

Have your end users enter their text in a flatpage with the URL say '/
homepage_text/'. In your view that builds the full homepage (dynamic +
static), make an explicit query to get the flatpage text:

from django.contrib.flatpages.models import FlatPage
static_text = FlatPage.objects.get(url='/homepage_text/')

Pass this text on to your template along with your dynamic parameters.

If your user entered text is really a bunch of properties and such,
you may be better off creating your model to capture them.

In short, you can treat the FlatPage model as a storage for elementary
key, value type properties with a key being FlatPage.url and a value
being FlatPage.content.

site is built with django, but my server doesn't know that...

[erica g]

I have very basic experience with Django templating and creating
models and apps.  The developer who built my site is gone and I am
trying to sort things out.  I know our site runs on Django.  I used to
have Django installed on my own machine and did all of my mini-
development work there (like creating models and apps and modifying
admin and public views).  Now I want to do that directly on the
server.  However when I try to do anything Django-ish, my server
doesn't seem to know that Django is installed.  Here is what I do and
what it all looks like:

log in as [EMAIL PROTECTED]

[EMAIL PROTECTED]:~# python
Python 2.5.1, Ubuntu 4.1.2 etc. etc.
>>>

So Python is installed and I've opened the interpreter, right?

Then this:

>>> import django [to verify that django is installed]

and I get

Traceback (most recent call last):
File "", line 1, in 
ImportError: No module named django
>>>

Any ideas??

Thanks!

Re: Start development: which branch?

[Tim Chase]

> Should I use trunk for development? Or is there any branch

I think the general rule of thumb is:

If you absolutely must have a stable API, and don't need anything 
more than what 0.96 offers (lots of new features and 
functionality have been added since then), use 0.96

Otherwise, use trunk.

This does mean accomodating the occasional change that breaks 
backwards compatibility as documented here [1] but trunk is 
production-worthy most of the time (just be sure to test and 
track the below URL to make sure your code doesn't break between 
versions of Django).  However, using trunk also allows access to 
the latest and greatest features too.

Hey Marty,

That also sounds really interesting - although Flatpages didn't solve

on and they are now part of my site (Thanks Rajesh!).

I have to initially go live with this on Sunday (madness) but your

Now, I am more confused about your actual problem. You say in the
original post that when you use FooForm as a base "form" parameter in
form_for_instance, you don't get fields from Foo. But in the code
above, both FooForm and Foo have the same field named 'title'. In such
a case, you wouldn't need to use the form=FooForm parameter at all.
Just form_for_instance(foo) and form_for_model(Foo), would work.

Here is an example of using a custom form base class that is intended
to add a new field to the set of fields that are created from the Foo
model. Notice how this adds the new field 'another_title' in the
__init__ method instead of adding it as a class field:

class FooForm(forms.BaseForm):
def __init__(self, *args, **kwargs):
super(FooForm, self).__init__(*args, **kwargs)
self.fields['another_title'] = forms.CharField(label =
_("Title2"))

Re: Does anyone know a good method for creating one time pages with Django?

[[EMAIL PROTECTED]]

Thanks, flat pages look really useful.

Unfortunately I don't think they solve my problem here - the rest of
the page needs to be dynamic and driven by custom content; it's only a
subset of the page elements that I want to be static in this way. I
suppose what I'm looking for is a kind of properties section for the
site. It might not exist in Django of course - typically I would
imagine this kind of thing would exist in the template. Unfortunately
the site needs to be managed by a non technical user so they wont be
up to editing templates.

If nothing does exist I'm sure I can write something better but
deadlines are pressing at the moment and it seemed like a proplem
someone else was likely to have encountered before.

I'm working on an app[1] that might help you out. It's basically a way
to easily create a site with modules, similar to how Google's homepage
works, but your apps would provide the modules for the site. You'd be
able to let users add/remove/customize some modules, while others
would always be there, regardless of the current user's preferences.
They'd even show up for users who aren't logged in.

I'm still doing a lot of work on it at the moment, though, so I don't
expect it to do everything you're looking for until sometime in the
next couple weeks. It currently works to an extent, but it's fairly
primitive, doesn't have all the options it needs, and has no
documentation. If it sounds like what you need, though, I'll keep you
posted on my progress.

The Python interpreter can't find the module 'django'.

At runtime the path is stored in sys.path.

You can debug this:
import sys
assert False, sys.path

You have several options:
 1. modify the environment variable PYTHONPATH
 2. modify sys.path:
   sys.path.append('/yourpath')
 3. Move the django directory (the one that contains e.g. 'newforms')
to a place on your sys.path.

name 'django' is not defined

[Florian Lindner]

Hello,
I'm using Django trunk.

After some weeks of paused development I started my app again today. But as 
soon as I access the URL defined at the root urls.py:

(r"^blog/", include("xgm.Blog.urls")),

I get an error:

Error while importing URLconf 'xgm.Blog.urls': name 'django' is not defined

The first line of xgm.Blog.urls is:

from django.conf.urls.defaults import *

The app is started with the manage.py script.

Anyone got an idea whats is wrong here?

Thanks,

Does anyone know a good method for creating one time pages with Django?

[[EMAIL PROTECTED]]

Hi,

Could anyone recommed a good method for creating one time pages with
Django. What I want to do is create something like a homepage class
that would contain things like the message of the day. However I only
want ever want one copy of the homepage - I don't want the user to be
able to create additional ones.

At the moment I done this by creating a single instance of the
homepage, removed the add more link from the index page and linked
directly to the edit page for this instance. However this seems messy
and I feel like I'm working against Django. Is there a better way of
doing it?

Thanks,

Ben

Yes, that was clear to me.

But why does the root urls.py works that also contains the line

from django.conf.urls.defaults import *

or the manage.py script or another installed app in the same project 
directory?

I knew about being able to populate the database using the method that

AUTH_PROFILE_MODULE usable with v0.96?

[paulc]

I'm trying to follow the example in the Django book, to make a simple
extension of the standard User object.

I'm hoping someone may be able to give me a quick yes or no on this:
is the AUTH_PROFILE_MODULE setting expected to work with Django 0.96,
or do I need to upgrade to the SVN release?

Within a very simple view that I'm using just to try this out, I can
pick up the User object and access some of its fields (e.g. username)
and custom methods (e.g. is_authenticated);  but if I call the
get_profile() method, I see the following error:

Exception Type: AttributeError
Exception Value:'NoneType' object has no attribute
'_default_manager'

I'm pretty sure I have AUTH_PROFILE_MODULE set correctly (I do not get
the `too many values to unpack' error).

I do not see the SiteProfileNotAvailable error, which again seems to
suggest I have all the necessary middleware and settings present in
the configuration.

Also, I test the User object's is_authenticated attribute, and confirm
that returns true; as expected, is_anonymous returns false.   That
seems to rule out the possibility that I'm dealing with an
AnonymousUser object.

Also, I found and read the Django tips article re. extending the user
model (http://www.b-list.org/weblog/2006/jun/06/django-tips-extending-
user-model/), but still can't see that I'm doing anything wrong in the
code or settings.

Any feedback much appreciated.

- Paul

You could set the clean method like this, but this is
a cleaner way:

from django import newforms as forms
class MyForm(forms.BaseForm):
def clean(self):


forms.form_for_model(..., form=MyForm)

Using MultiWidget

[PlanarPlatypus]

Hi,
I am trying to write a request Tracking system using the following
models (Re-ordered and some fields removed for clarity)

class Request(models.Model):
packages=models.ManyToManyField(Package)

class Package(models.Model):
product=models.ForeignKey(Product)
components=models.ManyToManyField(ComponentVersion)

class Product(models.Model):
name=models.CharField(max_length=60)
required_components=models.ManyToManyField(Component)

class Component(models.Model):
name=models.CharField(max_length=60)

class ComponentVersion(models.Model):
component=models.ForeignKey(Component)
version=models.PositiveIntegerField()

I need to present an interface where the user first creates a request
by selecting 1 or more Packages (done) and is then presented with a
page containing a series of dropdowns allowing them to chose the
ComponentVersions for the packages' products grouped by their
component.

At the moment I have got a set of queries which gives me a list of
querysets for the relevant ComponentVersions.  I was looking at having
a ModelChoiceField for each of these and constructing the form
dynamically but this is messy to validate.  Is there an easier/cleaner
method of doing this?
