How to properly extend the user class in django?

Question

Django

New project on django 1.9
I'm trying to extend the standard User class and make registration.
The example was taken from here stackoverflow.com/questions/21779226/abstractuser-...
But it didn't work. When registering superuser I get an error.
django.db.utils.IntegrityError: NOT NULL constraint failed
how to make view.py right? I think there is an error.
Can someone throw off an example with inheritance from AbstractUser and a registration form?

If you add required fields, then you should rewrite the create_user and create_superuser methods
