Re: ImportError: No module named 'main'

Hi,

I agree with Samuel Muiruri, your app definition in settings.py is incorrect.

try this:

INSTALLED_APPS = [ ... #'DjangoRestfulServer', #remove there is no need toimport the main project 'main', #no need for substantiating an app ]

Could you tell why Django does not see 'main' application?
