Check out the django 1.4 docs on serving static files in development. If you're not using the built in django server you'll need to add this to your urls.py file. making sure that your STATIC_DIRS and STATIC_URL settings are properly configured.
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
# ... the rest of your URLconf goes here ...
urlpatterns += staticfiles_urlpatterns()
As noted in the docs, you'll need to make sure DEBUG = True
in your settings.py.
If you're using the built in django server you just need to put your static files in a directory called static at the top level of your app and it will just work.
