#7813: Problem Pickling Querysets
-------------------------------------------+--------------------------------
Reporter: Ed Menendez <[EMAIL PROTECTED]> | Owner: nobody
Status: new | Milestone:
Component: Uncategorized | Version: SVN
Keywords: queryset pickle | Stage: Unreviewed
Has_patch: 0 |
-------------------------------------------+--------------------------------
I saw a previously closed [http://code.djangoproject.com/ticket/7506
ticket 7506] for a related (no pun intended) problem. It seems like when
we use select_related suddenly the queryset can't be pickled. This used to
work back in May sometime. Currently using SVN 7944.
The models is attached.
{{{
# This works
ld = LeagueDivision.objects.all()
cache.set('test2', ld)
# This doesn't work
ld = LeagueDivision.objects.select_related('league_conference').all()
cache.set('test2', ld)
}}}
Traceback (most recent call last):
File "<console>", line 1, in <module>

TypeError: can't pickle function objects
The dev environment is Windows, Python 2.5.1 using runserver built in web
server with memcache (also on Windows) and Postgres 8.2 on Windows.
