引入:


from django.db import models
from django.contrib.auth.models import AbstractBaseUser

源码 :

from django.contrib.auth.models import User  
(user指的是 auth_user表)
User源码=====》
class User(AbstractUser):
    """
    Users within the Django authentication system are represented by this
    model.

    Username and password are required. Other fields are optional.
    """
    class Meta(AbstractUser.Meta):
        swappable = 'AUTH_USER_MODEL'

 

1:setting设置

AUTH_USER_MODEL="app01.UserInfo"     #表示哪张表继承了auth_user表(在给auth_user添加字段用到)

2:增加表字段

from django.contrib.auth.models import AbstractUser

class UserInfo(AbstractUser):
    r_pwd=models.CharField(max_length=32)

3:数据库迁移

python manage.py makemigrations    #同步
python manage.py migrate

4:效果

auth_user 表名被改为  auth_userinfo。且添加了一个字段

 5. 数据迁移

makemigrations users 会出错,django.db.migrations.exceptions.InconsistentMigrationHistory: Migration admin.0001_initial is applied before its dependency users.0001_initial on database 'default'.

Django-组件--用户认证Auth(auth_user增加字段)

 

 

 

 

 

 

 



直接:

makemigrations
migrate
