无法使用有效的用户名和密码登录到django管理员页面

编辑：

我在amazon AWS上托管了一个网站，域名为say（www.abc.com）

首先：我尝试登录到django管理站点，但它再次重定向到同一页面，没有显示任何错误（注意：用户名和密码正确）

第二步：成功注册后，尝试使用用户名和密码登录django内部页面： 它通过在url之间添加next关键字重定向到同一登录页面

http://www.abc.com/login/?next=/employee/jcbdfvdhdfhvhdfsvsdhfhb-super-admin/home/dashboard/

在调查服务器后发现一件事：

我已经停止了所有应用程序，如wsgi、Supervisorctl、ngnix等。 然后在ec2 aws控制台（终端）上运行以下命令

注意：xxx.xx.xx.xx是我的域名（www.abc.com）IP

它成功地登录到django管理站点以及项目内部页面

在djano环境中，我缺少什么吗？ 我被这个问题困扰了很长时间。任何答案都将是可观的

请问我，如果你需要从我的项目代码

选中此处的所有选项：

这看起来像是“挂不住的果实”，但我也经常遇到类似的问题（登录到Django Admin后，会在没有明显原因的情况下返回到登录页面）。每次都被证明是一个解决方案，就是清除我的浏览器缓存和cookie…所有这些（而不仅仅是最后一个小时左右）

希望这能有所帮助。

您的设置文件似乎很好。您是否将Gunicorn与多个工作人员一起使用，如果是，请尝试仅与单个工作人员一起使用。实际上，会话不会在多个工作进程之间传输，除非您将一些中间层存储组件（如memcached或redis）带到会话中。一段时间以前也面临同样的问题。希望它能解决您的问题：）

首先尝试注释以下所有行， 然后重新启动服务器

#AUTHENTICATION_BACKENDS = ('custom.backends.EmailOrUsernameModelBackend','django.contrib.auth.backends.ModelBackend')

#   'apps.communication,

#AUTHENTICATION_BACKENDS = ('django.contrib.auth.backends.ModelBackend',)
#SESSION_EXPIRE_AT_BROWSER_CLOSE = True
#SESSION_SAVE_EVERY_REQUEST = True
#SESSION_COOKIE_AGE = 86400 # sec
#SESSION_COOKIE_DOMAIN = '.abc.com'
#SESSION_COOKIE_NAME = 'DSESSIONID'
#SESSION_COOKIE_SECURE = False

我注意到的事情：

1：在已安装的应用程序中，

“应用程序通信”后缺少撇号

INSTALLED_APPS = (
   'django.contrib.auth',
   # -- snip --
   'apps.communication,
)

2：您已经定义了两次Authentication\u后端。在这种情况下，您的第二个元组只是踩在第一个元组上

3：身份验证后端的顺序很重要

4:您不需要列出'django.contrib.auth.backends.modelbend'，因为如果安装的应用程序中有'django.contrib.auth'，将对其进行搜索。（您已配置）
服务器对/employee/jcbdfhddfhdhhdfsvsdhfhb super admin/home/dashboard/的响应是什么？也许您没有正确地检查用户是否登录…它的附件是下一步，而不是进入仪表板，它再次进入登录页面：url:login/？next=/employee/JCBDFVDHDFSVSDHFHB super admin/home/dashboard/注意：用户名和密码已验证，我已在Shells上进行了检查您是否使用自定义身份验证模型？您是否可以发布您的设置文件？您是否检查了nginx错误日志以查看是否遇到任何问题？对于日志处理程序，我使用了django auth模型。但是让我的loginMixin处理程序保存用户名和密码谢谢@ankurloader，这挽救了这一天！因为在解决django的登录问题时没有任何错误迹象！
INSTALLED_APPS = (
   'django.contrib.auth',
