USERNAME_FIELD
A string describing the name of the field on the User model that is used as the unique identifier. This will usually be a username of some kind, but it can also be an email address, or any other unique identifier. The field must be unique (i.e., have unique=True
set in its definition), unless you use a custom authentication backend that can support non-unique usernames.
In the following example, the field identifier
is used as the identifying field:
class MyUser(AbstractBaseUser): identifier = models.CharField(max_length=40, unique=True) ... USERNAME_FIELD = 'identifier'
USERNAME_FIELD
now supports ForeignKey
s. Since there is no way to pass model instances during the createsuperuser
prompt, expect the user to enter the value of to_field
value (the primary_key
by default) of an existing instance.
