I have a model which in essence boils down to this:
class Person(models.Model):
name = models.TextField()
class MarriedMan(Person):
wife = models.OneToOneField(Person, on_delete=models.CASCADE,
related_name='husband')
But when I try to generate the migration, I get the following error:
django.core.exceptions.ImproperlyConfigured: Add parent_link=True to
> webapp.MarriedMan.wife.
It looks like Django is promoting the wife OneToOneField to be the
parent_link relationship. But that's not what I'm trying to do. I want
MarriedMan to have the default implicit OneToOneField for its parent class
Person record, plus an extra OneToOneField for its wife.
As far as I was able to understand from the docs, the way to specify that
this is not my intention is by not passing parent_link=True.
If you want to control the name of the attribute linking back to the

As a workaround I could manually specify the parent_link relationship in
addition to the wife field, but that doesn't seem like the correct solution.
Am I missing something?
Thanks.
