Trouble installing django_shop_discounts

Question

I am following the Getting Started Guide from readthedocs.org here for setting up django_shop_discounts

I aim to add coupon codes to an existing django shop

But when I do runserver I get the following error ImportError: No module named polymorphic_model

I have installed Polymorhpic but still get the same error.

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.sites',
    'debug_toolbar',
    'pipeline',
    'grappelli',
    'django.contrib.admin',
    'django.contrib.admindocs',
    'south',
    'extras',
    'photos',
    'payments',
    'accounts',
    'shop',
    'discount.default_discounts',
    'cart',
    'couriers',
)

This is where my "discount" folder is along with other apps

This is what is inside my "discount" folder

Answer 1

It is likely there are errors in your Python models. or you are missing the trailing , after your

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

But to make sure can you put the models up in your question and the installed apps so we can check for you.
