Answer 1

As @dragonx said the error was because I was using latest branch of django-nonrel and which didn't support completely django1.5 and so on. I didn't try to resolve it either because we have better options with better support and functionalitites to deploy app on PAAS such as HEROKU. So I moved on to HEROKU.

Usually errors like this come from mismatching versions of django, djangoappengine or django-toolbox. You'd want to double check to make sure you have the right version of each.
