引入:
from django.db import models
from django.contrib.auth.models import AbstractBaseUser
源碼 :
from django.contrib.auth.models import User (user指的是 auth_user表) User源碼=====》 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設置
AUTH_USER_MODEL="app01.UserInfo" #表示哪張表繼承了auth_user表(在給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:數據庫遷移
python manage.py makemigrations #同步 python manage.py migrate
4:效果
auth_user 表名被改為 auth_userinfo。且添加了一個字段
5. 數據遷移
makemigrations users 會出錯,django.db.migrations.exceptions.InconsistentMigrationHistory: Migration admin.0001_initial is applied before its dependency users.0001_initial on database 'default'.
直接:
makemigrations
migrate
