Questions about setting AUTH_USER_MODEL arise
There was a bug when running:
AttributeError: type object ‘UserProfile’ has no attribute 'USERNAME_FIELD’
Solutions are available online: adding user.models inside:
Django model given rewrite user has no attribute 'USERNAME_FIELD'
identifier = models.CharField(max_length=40, unique=True)
USERNAME_FIELD = 'identifier'
But this question that arises is: identifier amount is not what we want to set. At the same time when creating a super-user, the addition is complete identifier will appear warning!
In looking for solutions found missing

objects = UserManager()
After running, although you can set up a password, but the mailbox settings, set the nickname still invalid ;
The following code is by looking for "USERNAME_FIELD" the code key, the program found inside;
class AbstractUser(AbstractBaseUser, PermissionsMixin):
"""

admin-compliant permissions.

Find the problem, add the class error. In a video explaining the inherited class is "AbstractUser", and I use the class is "AbstractBaseUser". Inherited wrong!
