Is it possible to order a queryset by a custom field?
I have several programmatic generated fields and need to sort the
display by them, is this possible?
Thanks

As far as i know, select_related doesn't work across reverse
relationships. Sometimes it's possible to just query the base model to
achieve the same results, but not always.
Maybe its a good feature for the query.py rewrite, but i'm thinking it
could get ugly pretty fast. It would require a new
Great stuff again Malcolm. Perhaps it should be rehashed a bit and put
in the newforms docs under 'custom validation' ?
Just a thought :)

Malcolm,
Thank you so much for discovering my problem, I was hoping it was the
newforms code and not mine ;-P.
Yea, that form= trick seems to work, not sure why, but it does. I've
also seen the callback one too, but that seemed rather complicated,
and I'm not much for complicated code :-

I'm building a blog using Django, and am wanting to use django-tagging

I've added the tagging app to my INSTALLED_APPS in the settings.py
file. It is located inside my project, which is also

Malcolm,
Here is the traceback from line 41:
c:\python24\lib\site-packages\django\newforms\models.py in

34. opts = instance.__class__._meta
35. if form.errors:

Last one, promise.

Ok, I've got to be pretty close here. I went ahead and created an
empty app with just a template tags directory mmtags/templatetags/
mm_markup.py ...
I believe I have performed exhaustive research on the challenge of
creating forms that incorporate fields from multiple tables. I have
not found *any* comprehensive, best-practices examples of this problem.
It really quite surprises me, as any web application of even moderate
complexity

Looking at the urls pattern reported in the 404 page it looks like there is
twice the "^" symbol.
And I would say that is the problem because this symbol tries to match the
"start of a line", so the pattern
"^news/ ^/(?P[a-zA-Z0-9-_]+)/?$" will never match to "/news/hello/".
my guess is that you
Hmm, I suppose another approach and possible horrible hack might be:

2. Votes are appended to the queue and immediately added to the
UserContentRelationship table.
3. A separate thread processes the queue periodically to ensure atomic
updates to

Yes, this is yet another voting design discussion.
As far as I can see there are two approaches:
1. A separate table that records the User-Content relationship
including the vote -1/0/+1
and, optionally:
2. A voting field in with the content that gets atomically updated
with each vote.
