Django, apache and mod_wsgi

Question

I am trying to deploy an Apache webserver with a Django installation.

I have installed Apache 2.2.25 (is working) and mod_wsgi 3.5.

In my error log I get

[Sun Oct 05 10:09:10 2014] [notice] Apache/2.2.25 (Win32) mod_wsgi/3.5 Python/3.4.1 configured -- resuming normal operations

So I think something might be working.

The problem arises when I go to http://localhost/. I get a 500 Internal Server Error.

The error log says:

So the problem seems to be AttributeError: 'RegexURLResolver' object has no attribute '_urlconf_module'\r. First I thought it must be something with my project, so I've tried not loading any apps, but even with a clean django project it causes the problem (I have checked if it works with the normal django development server).

Can anyone see what I am doing wrong?

Edit (error log when omitting admin.autodiscover() from urls.py):

The Apache configuration is

WSGIScriptAlias / C:/Users/Username/Dropbox/myproject/myproject/wsgi.py
WSGIPythonPath C:/Users/Username/Dropbox/myproject;C:/Python27;C:/Python27/Lib

<Directory C:/Users/Username/Dropbox/myproject/myproject>
<Files wsgi.py>
Order deny,allow
Allow from all
#Require all granted
</Files>
</Directory>

Answer 1

It seems to be related with the version of python.

And it seems you got a wrong value for WSGIPythonPath, which should point to the folder of python executable i.e. python.exe, not the project.

Answer 2

The problem was that the correct way to create the wsgi app was edited between django 1.6 and 1.7 to

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

Now it works in both python 2.7 and python 3.4
