IIS 上的 Django：django.core.exceptions.AppRegistryNotReady：尚未加载应用程序

Question

我一直在玩微软的 Django 教程，它在我的 Visual Studio 2015 环境中使用 Python 3.4.3 运行良好。当我尝试通过我的网络服务器运行它时，它失败了：

Error occurred:

当我通过网络服务器上的“manage.py runserver”测试代码时，它运行良好。在通过 IIS 运行时，是否有人对如何调试问题有任何建议？

服务器也在运行 Python 3.4.3，安装了 django、django-crispy-forms、wfastcgi 和 mysqlclient。 Python 在带有 IIS 8.5 的 Windows 2012 R2 服务器上通过 FastCGI 执行 - 使用https://azure.microsoft.com/en-us/documentation/articles/virtual-machines-python-django-web-app-windows-server/ 的指南完成配置

我试过了：

1) 在我的 manage.py 中的“os env...”下添加以下内容：

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

2) 在我的 manage.py 中的“os env...”下添加以下内容：

import django
django.setup()

正如其他人在其他线程中提到的这些解决方案，但不幸的是没有任何运气。我对 Python/Django 都是全新的，所以我不知道如何继续。任何意见将不胜感激！

原来链接的微软指南已经过时了。

在web.config中，需要替换以下内容：

<add key="WSGI_HANDLER" value="django.core.handlers.wsgi.WSGIHandler()" />

与：

<add key="WSGI_HANDLER" value="django.core.wsgi.get_wsgi_application()" />

然后它就会工作:-)
