• 声明用户模型

# 替换用户模型
AUTH_USER_MODEL = "users.UserProfile"

• 视图

from django.contrib.auth import get_user_model
from django.contrib.auth.backends import ModelBackend
from django.db.models import Q

User = get_user_model()

class CustomBackend(ModelBackend):
    """自定义用户验证"""

        #     username = kwargs.get(UserModel.USERNAME_FIELD)
        try:
            user = User.objects.get(Q(username=username)|Q(mobile=username))
        except User.DoesNotExist:
            # Run the default password hasher once to reduce the timing
            # difference between an existing and a nonexistent user (#20760).
            User().set_password(password)
        else:
