it was https://docs.djangoproject.com/en/dev/ref/settings/#static-root
it's easy:
you have to set a settings.py file. yours it's a bit mess. try this: rename it to settings_test.py
and create a new one
copy the new one from a django default project
and then tune it with media/static value and tune the main urls.py and other value like db etc etc that works from the older. don't change the order, don't move up&down things that you don't know.
