django admin 操作重写用户模型 实例 带用户和权限组的

 项目目录结构

续：自定义权限限制url访问权限：点我

models.py

    PermissionsMixin , AbstractBaseUser,UserManager
)


class MyUserManager(UserManager): #这里是重写了创建用户和超级用户的方法，因为自己的表中不需要用户写如emali

admin.py

from django import forms
from django.contrib import admin
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin
from django.contrib.auth.forms import ReadOnlyPasswordHashField

from accounts.models import MyUser

admin.site.register(MyUser)

settings.py   一定要加这句话

AUTH_USER_MODEL = 'accounts.MyUser'

注意：这个一定要在项目刚创建的时候写好，然后在开始第一次的  python  manage.py makemigrations     python manage.py migrate

 效果如下
