Trouble with deploying Django app with Git submodule

Question

I'll try to skinny this question as best as I can so that it's not too vague.

So I'm using this django-ajax-validation plugin in a Django app. I'm fairly certain that the problem I'm running into lies somewhere between my settings.py and Heroku. When I deploy I get this error message:

2013-03-08T18:54:17+00:00 heroku[web.1]: Starting process with command python manage.py runserver 0.0.0.0:53994 --noreload
2013-03-08T18:54:18+00:00 app[web.1]: Error: No module named ajax_validation
2013-03-08T18:54:19+00:00 heroku[web.1]: Process exited with status 1
2013-03-08T18:54:19+00:00 heroku[web.1]: State changed from starting to crashed

In my installed apps I have:

INSTALLED_APPS = (
    'ajax_validation',

among other things.

In the django-ajax-validation docs the author mentions adding ajax_validation/ to your PYTHONPATH and ajax_validation to your INSTALLED_APPS in order to install the plugin. Maybe because I'm inexperienced, I found the former step vague and the closest thing I could find was installing his setup.py file with python setup.py install

Is this incorrect? Is there a different way to add the app as a module?

Let me know if I need to clear anything up.

Good news for you, Heroku supports python packages installation via pip, which is a very usefull tool to manage django apps. Everything is explained on Heroku’s website: https://devcenter.heroku.com/articles/python-pip.
