Comment (by Petr Marhoun <[email protected]>):
Ticket #13356 was closed as duplicate of this patch - It is true that is
seems to be quite similar and there is more information here. But I think
that it has more simple example of the problem and it could be also here.
Following code works :
{{{
#!python
from django.contrib.auth.models import User
from django.db.models import Count
User.objects.filter(id__in=[]).annotate(Count('groups'))
[]
User.objects.filter(id__in=[]).count()
0
}}}
But following code raise !EmptyResultSet:
{{{
#!python
User.objects.filter(id__in=[]).annotate(Count('groups')).count()
}}}
