I have models
{{{
class Place(models.Model):
pass
class Community(Place):
place_ptr = models.OneToOneField(Place, parent_link=True,
on_delete=models.CASCADE,
primary_key=True, serialize=False, related_name='+')
class Potential(models.Model):
community = models.ForeignKey(Community, on_delete=CASCADE)
}}}
and in 1.10 I can do
{{{
Potential.objects.filter(community__in=Place.objects.all())
}}}
but in 1.11 this fails with
{{{
django.core.exceptions.FieldError: Cannot resolve keyword 'place_ptr' into
field. Choices are: [...]
}}}
In both versions
{{{
Potential.objects.filter(community=Place.objects.first())
}}}
works fine.
It's not clear to me from the docs whether the 1.10 behavior was intended,
though.
