# User.objects.create (username = username, password = password) # create a user name and then use the time do not create the 
# User.objects.create_user (username = username, password = password) # Create a regular user
 User.objects .create_superuser (username = username, password = password, Email = ' [email protected] ' )   # create a super user Email (required)

Three: Custom Form auth_user

    # The second way to use class inheritance 
class Userinfo (AbstractUser):
 # Do not repeat the only innovation in the field with the original table 
        Phone = models.BigIntegerField () 
        Avatar = models.CharField (max_length = 32 ) 
            
    # must be in configuration file tells Django 
    # tell django orm no longer use the auth default table but use your custom table 
    AUTH_USER_MODEL = ' app01.Userinfo '   # 'application name. class name'

PS：

　　(1) perform a database migration command
　　(2) all auth module functions are all based on the table you created
　　(3) no longer use auth_user
