python/django models中自定义用户认证及django admin自定义

python django models中自定义用户认证

#(一)
#简单的用户验证
# from django.contrib.auth.models import User
# class UserProfile(models.Model):s
#     ‘‘‘堡垒机账户‘‘‘
#     user = models.OneToOneField(User,on_delete=models.CASCADE)  #django官方推荐的简单方法，缺点是找user时要a.user.username
#     name =models.CharField(max_length=32)
#
#     def __str__(self):
#         return self.name
#(二)
#常用的版本，自定义
#导入自定义用户认证表 UseProfile

from django.contrib.auth.models import (
    BaseUserManager, AbstractBaseUser
)
#自定义用户认证
class UserProfileManager(BaseUserManager):
    def create_user(self, email, name, password=None):
        """
        Creates and saves a User with the given email, date of
        birth and password.

        "Is the user a member of staff?"

 在settings.py中加上
     #用自定义的用户认证 （app名+表）
     AUTH_USER_MODEL = ‘web.UserProfile‘

django amdin自定义

在admin.py中导入py文件，就会自动执行注册（admin.site.register(UserProfile, UserAdmin)）
