Description

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.
