django 如果在多个app使用各自的用户多认证

这个不能再settings.py里面直接配置，配置了以后这个配置文件写的就是袭腊默认Auth系竖禅嫌统了，想要用到各自的用户表来余手认证话，你在每个App的models.py和admin.py里面分别继承Django自带的Auth系统，from django.contrib.auth import authenticate, login, logout这句话就可以解决views里面的登录与退出；from django.contrib.auth.models import User就可以继承User的models。

觉得好的话采纳一下哦

不是使用自带admin的时候，有个配置文件捏，主要在那个文件里面改就好了，admin的实质其实就是一个工厂而已，配置了在系统第一次加载的时候就已经全部生成，默认路径是admin，既然你自己写了admin模块，你把你写的url路径换一个，那么在访问的时候，就两个都能访问了撒，比如你的admin最开始雀册渗的基本路顷脊径叫admin1，就和默认admin分开了，想用那个服务，调用哪一姿凯个就好了

首先，让我们开始创建项目和APP，前面我也很详细的说明了大悄如何创建项目和APP。

创建数据库，和相关用户的权限。

使用python manage.py syncdb 来创建一个叫jastme,密码为jastme的超级用户。我们可以用Django-admin来管理这些用户配早。

首先看看setting.py

root@CD-FTP-VPN:/opt/jastme# more jastme/培仿雀settings.py
