Django unique_together on sub-class model for parent attribute?

Question

In this:

class Administrator(models.Model):
    user = models.OneToOneField(User, primary_key=True)
    account = models.ForeignKey(Account)

    class Meta:
            


        

Answer 1

It would be

unique_together = (('account', 'user__username'),)

if I understand what you're trying to do. Note the double underscore. That's how you look at a foreign key's object's properties.
