Comment (by Sage Abdullah):
Thanks both! Here's a much more minimal reproduction that still somewhat
makes sense.
{{{
from django.contrib.contenttypes.fields import GenericForeignKey,
GenericRelation
from django.contrib.contenttypes.models import ContentType
from django.db import models
class Generic(models.Model):
content_type = models.ForeignKey(
ContentType,
related_name="+",
on_delete=models.CASCADE,
)
object_id = models.CharField(max_length=255)
content_object = GenericForeignKey()
class Abstract(models.Model):
@property
def generics(self):
return Generic.objects.filter(
content_type=ContentType.objects.get_for_model(self),
object_id=str(self.pk),
)
class Meta:
abstract = True
class Concrete(Abstract):
generics = GenericRelation(Generic, related_query_name="concrete")
}}}
