I'm not sure if this is a feature request or a bug fix :) This seemed to
work a few weeks ago, and it no longer does. Whether or not the feature
was intentional, it was quite useful--being able to query parent models
for child instances. Given the following model:
{{{
from django.contrib.auth.models import Group
class Team(Group):
pass
}}}
I want to query the Groups to find out which are Teams. This used to work
{{{
>>> g = Group.objects.create(name='group1')
>>> t = Team.objects.create(name='team1')
>>> Group.objects.filter(team__pk__isnull=False)
[<Group: team1>]
}}}
But instead now I get the following:
{{{
>>> Group.objects.filter(team__pk__isnull=False)
[<Group: group1>, <Group: team1>]
}}}
Ideally, it would be nice to simplify this to:
{{{
>>> Group.objects.filter(team__isnull=False)
[<Group: team1>]
}}}
But just getting it to work again would be nice.
