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 tutoiral,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,它运行得很好.有没有人在通过IIS运行时有任何关于如何调试出错的建议？

服务器也运行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 - 配置是使用https://azure.microsoft.com/en-us/documentation/articles/virtual-machines-python-django-web-上的指南完成的.APP-Windows的服务器/

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这些解决方案,但遗憾的是没有任何运气.我对Python/Django都是全新的,所以我不知道如何继续.任何输入将不胜感激!

事实证明,链接的Microsoft指南已过时.

在web.config中,需要替换以下内容:

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

有:

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

然后它会工作:-)
