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'
一: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'.
