I have a model which essentially 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 make the migration, I get the following error:
django.core.exceptions.ImproperlyConfigured: Add parent_link=True to
> webapp.MarriedMan.wife.
It seems like Django is automatically promoting my OneToOneField to be the
one which holds the reference to the parent class. But that's not what I
intended. I want there to be an extra wife relationship in addition to the
implicit automatic OneToOneField.
As far as I could tell from the documentation, that's exactly what NOT
passing parent_link=True is supposed to signify:
If you want to control the name of the attribute linking back to the
> parent, you can create your own OneToOneField and set parent_link=True to
> indicate that your field is the link back to the parent class.
As a workaround I could explicitly define the parent_link relationship plus
my own wife relationship, but that doesn't seem to be the correct solution.
Am I missing something?
Thanks.
