引入:

from django.db import models

from django.contrib.auth.models import AbstractBaseUser

原始碼 :

from django.contrib.auth.models import User　　
（user指的是　auth_user表）
User原始碼＝＝＝＝＝》
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　表的欄位

１：setting設定

AUTH_USER_MODEL="app01.UserInfo"     #表示哪張表繼承了auth_user表（在給auth_user新增欄位用到）

２：增加表字段

from django.contrib.auth.models import AbstractUser

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

３：資料庫遷移

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

４：效果

auth_user 表名被改為  auth_userinfo。且添加了一個欄位

 5. 資料遷移

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
