How do I model a symmetric relationship with django?

Question

Let\'s use the classic example of friends.

class Friendship(models.Model):
    user1 = models.ForeignKey(User, related_name=\'friends1\')
    user2 = models.

Check out the symmetrical option of ManyToManyField in the docs -- sounds like it can do what you want.

For the specific way you're doing it, I'd do something like

class LameUserExtension(User):
    friends = ManyToManyField("self", through=Friendship)

class Friendship(models.Model):
    # the stuff you had here
