Django：内部服务器错误

Question

这是我第一次在 DigitalOcean 上部署 Django 网站，这给我带来了很多问题。我正在使用一键安装，从 git 部署了我的网站并更改了 gunicorn 和 nginx 文件，但它仍然给我

Internal Server Error.

这是 Apache 日志：

2015-05-18 15:24:08 [20726] [ERROR] Error handling request Traceback

   line 31, in import$
       error_prefix, module_path, class_name)) ImproperlyConfigured: Module "django.contrib.auth.middleware" does not define a
   "SessionAuth$

实在搞不懂问题出在哪里，如何处理。

根据 documentation:

New in Django 1.7.

Allows a user’s sessions to be invalidated when their password changes. See Session invalidation on password change for details. This middleware must appear after django.contrib.auth.middleware.AuthenticationMiddleware in MIDDLEWARE_CLASSES.

因此，我的猜测是您没有使用 Django 1.7+，但您已经在 MIDDLEWARE_CLASSES.

中定义了 django.contrib.auth.middleware.SessionAuthenticationMiddleware

<= Django 1.6

参见Sessions Documentation。

To enable session functionality, do the following:

Edit the MIDDLEWARE_CLASSES setting and make sure it contains 'django.contrib.sessions.middleware.SessionMiddleware'. The default settings.py created by django-admin.py startproject has SessionMiddleware activated.

If you don’t want to use sessions, you might as well remove the SessionMiddleware line from MIDDLEWARE_CLASSES and 'django.contrib.sessions' from your INSTALLED_APPS. It’ll save you a small bit of overhead.
