Comment (by David Sanders):
felixx this looks like an issue with overriding the foreign model's
ordering.
If I repeat the test with Klaas' models and print the query it reveals it
still attempts to use `parent.id`:
{{{
class Parent(Model):
class Meta:
ordering = ["id"]
class Child(Model):
parent = ForeignKey(Parent, on_delete=CASCADE)
print(Child.objects.all().order_by('parent__asdf').query)
SELECT "sample_child"."id", "sample_child"."parent_id" FROM "sample_child"
INNER JOIN "sample_parent" ON ("sample_child"."parent_id" =
"sample_parent"."id") ORDER BY "sample_parent"."id" ASC
}}}
