Django--组件-用户认证Auth(auth_user增加字段)

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'

 

        增加 auth_user 表的字段      

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'.
