Difference between AbstractUser and AbstractBaseUser in Django?

Question

The use of AbstractUser and AbstractBaseUser looks quite similar.

from django.contrib.auth.models import AbstractUser, AbstractBase         


        

Answer 1

The AbstractUser is basically just the "User" class you're probably already used to. AbstractBaseUser makes fewer assumptions and you have to tell it what field represents the username, what fields are required, and how to manage those users.

If you're just adding things to the existing user (i.e. profile data with extra fields), then use AbstractUser because it's simpler and easier. If you want to rethink some of Django's assumptions about authentication, then AbstractBaseUser gives you the power to do so.
