AttributeError: 'Settings' object has no attribute 'ADMIN_MEDIA_PREFIX'

Question

i am trying to make a smart menu using ChainedForeignKey, but so far i am stuck with the import of ChainedForeignKey:

from smart_selects.db_fields import ChainedForeignKey 

I am using pydev on Eclipse. I downloaded the smart select package here: http://pydoc.net/Python/django-smart-selects/1.0.2/ and added it to my PYTHONPATH

when i debug i get:

Traceback (most recent call last):

AttributeError: 'Settings' object has no attribute 'ADMIN_MEDIA_PREFIX'

Any help appreciated

Marking the comment as answer for future reference:

Looks like ADMIN_MEDIA_PREFIX was not set.

Setting ADMIN_MEDIA_PREFIX='/static/' or any other appropriate value for ADMIN media would fix the issue
