Django - no module named app

I have been trying to get an application written in django working - but it is not working at all. I have been working on for some time too - and it is working on dev-server perfectly. But I am unable to put in the production env (apahce).

My project name is apstat and the app name is basic.

I try to access it as following

Blockquote http://hostname/apstat

But it shows the following error:

MOD_PYTHON ERROR

ProcessId:      6002
Interpreter:    'domU-12-31-39-06-DD-F4.compute-1.internal'

ServerName:     'domU-12-31-39-06-DD-F4.compute-1.internal'
DocumentRoot:   '/home/ubuntu/server/'

  File "/usr/lib/pymodules/python2.6/django/utils/importlib.py", line 35, in import_module
    __import__(name)
ImportError: No module named basic

My settings.py is as follows:

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'apstat.basic',
    'django.contrib.admin',
)

If I remove the apstat.basic, it goes through, but that is not a solution. Is it something I am doing in apache?

My apache - settings are -

<VirtualHost *:80>
        ServerAdmin webmaster@localhost

        DocumentRoot /home/ubuntu/server/
        <Directory />
                Options None
                AllowOverride None
        </Directory>

        <Directory /home/ubuntu/server/apstat>
                AllowOverride None
                Order allow,deny
                allow from all
        </Directory>

        <Location "/apstat">
                SetHandler python-program
                PythonHandler django.core.handlers.modpython
                SetEnv DJANGO_SETTINGS_MODULE apstat.settings
                PythonOption django.root /home/ubuntu/server/
                PythonDebug On
                PythonPath "['/home/ubuntu/server/'] + sys.path"
        </Location>

</VirtualHost>

I have now sat for more than a day on this. If someone can help me out, it would be very nice.

Does your basic have __init__.py?

You need to make sure that the project is in your PYTHONPATH. Maybe try to output the sys.path variable at the top of your settings file:

import sys
print sys.path

If this doesn't work with mod_python try to write it to a file:

import sys
file('/tmp/mysyspath.txt', 'w').write(repr(sys.path))

But even if that will work, here is a short warning: It's discouraged in the django community to use mod_python. It's no longer maintained by its creators and was never the best solution to deploy your django project. Please try mod_wsgi if its available for you on your server.
