Django deployment - can't import app.urls

I just moved a django project to a deployment server from my dev server, and I'm having some issues deploying it. My apache config is as follows:

<Location "/">
        Order allow,deny
        Allow from all
        SetHandler python-program
        PythonHandler django.core.handlers.modpython
        SetEnv DJANGO_SETTINGS_MODULE project.settings
        PythonDebug On
        PythonPath "['/home/django/'] + sys.path"
</Location>

Django does work, since it renders the Django debug views, but I get the following error:

ImportError at /
No module named app.urls

And here is all the 开发者_如何学Pythoninformation Django gives me:

Request Method: GET

Any ideas as to why I get an import error?

Add the project directory to sys.path.

My guess is that if you simply change your url configuration to reference "project.app.urls" instead of "app.urls", your problem will be fixed.

It seems that you've listed "project.app" in INSTALLED_APPS in your project's settings.py file, but you've referenced "app.urls" in your urls.py. You need to standardize and either always reference "app", and change your PythonPath to include the project directory, or always reference "project.app".

I would recommend to use virtualenv along with mod_python. Some instructions here: http://mydjangoblog.com/2009/03/30/django-mod_python-and-virtualenv/

It has the advantage of solving all your path problems, but also to allow to install extra modules (or even other versions of django) very easily.
