Django 'settings' object has no attribute

this is my first python project. I am having issues setting up a project someone else has written. I am getting the following 'Settings' object has no attribute 'FOXYCART_URL' here's the stack trace:

Environment:

Exception Type: AttributeError at /
Exception Value: 'Settings' object has no attribute 'FOXYCART_URL'

I was wondering where do I need to set the FOXYCART_URL attribute?
