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'.
