Sort by field in ForeignKey model

Question

I have created a Django model called Person, which has got a 'user' ForeignKey to django.contrib.auth.models.User

How can I set the ordering on class Person to self.user.first_name, self.user.last_name?

Answer 1

class Meta:
    ordering = ['user__first_name', 'user__last_name']

Should do the trick iirc
