User

Bases: AbstractBaseUser

Defines the base user class, useable in every app.

This is almost the same as the auth module AbstractUser since it inherits from it, but some fields are required, and the username is generated automatically with the name of the user (see generate_username()).

Raises:

Type	Description
PermissionDenied	If the user cannot see the object
