Heroku Django Celery: NameError: DATABASE name undefined

I follow this tutorial to get celery and django working for a hero.

However, I get this error in my logs when I put in the specified code for the worker:

2011-12-22T05:31:56+00:00 heroku[web.1]: Starting process with command `python canada/manage.py run_gunicorn -b "0.0.0.0:47336" -w 3`

2011-12-22T05:31:58+00:00 heroku[web.1]: Process exited

My settings.py options look like

import djcelery

djcelery.setup_loader()

BROKER_BACKEND = "djkombu.transport.DatabaseTransport"
CELERY_RESULT_DBURI = DATABASES['default']
...

When I synchronize before adding this line CELERY_RESULT_DBURI = DATABASES['default'], it works fine. According to the document

When you deploy the Django application, the compilation process adds the following code to your settings.py to use the DATABASE_URL environment variable:
