Question

我正在研究一个在Heroku上托管的Django应用程序。我可以使用我的用户名，密码登录管理员。但是在每次点击（或几秒钟后每次点击）时，它会再次将我重定向到登录页面，并将?next=/admin/model添加到网址。事实上有时它会让我多次登录才能让我查看管理控制台。此行为不会反映在本地部署中。管理员在本地工作得很好。

我尝试了这里提到的建议：https://docs.djangoproject.com/en/1.8/faq/admin/#i-can-t-log-in-when-i-enter-a-valid-username-and-password-it-just-brings-up-the-login-page-again-with-no-error-messages。但这没有用。

任何线索我可能做错了什么？

这是我的settings.py：

Answer 1

在我的情况下，这发生是因为我同时运行另一个Django开发服务器（相同的域，不同的端口）。我不知道导致此问题的原因的详细信息，但关闭其他服务器解决了问题。

EDIT
如果您错过了问题中链接的文档：如果您需要运行多个django服务器，则可以通过为每个服务器设置不同的SESSION_COOKIE_NAME来解决此问题。

Answer 2

如果其他人遇到这种情况，我会遇到完全相同的问题，并最终意识到如果密钥尚未设置为event.failed文件，我会在SECRET_KEY文件中随机生成settings.py值环境变量。我完全忘了在Heroku上设置它，之后问题就解决了。

Answer 3

'django.contrib.auth.middleware.SessionAuthenticationMiddleware'，

我认为这样做会有所帮助。 https://docs.djangoproject.com/en/1.8/ref/middleware/#django.contrib.auth.middleware.SessionAuthenticationMiddleware]

Django管理员在每次点击后都要求登录
