[Python] Error 111 connecting to localhost:6379. Connection refused. Django Heroku

I am able to run redis locally and everything works.

However when I deploy to heroku I get this error:

Error 111 connecting to localhost:6379. Connection refused.


I have set up a Procfile with...

web: gunicorn odb.wsgi --log-file -
worker: python worker.py


I have a worker.py file...

import os
import urlparse
from redis import Redis
from rq import Worker, Queue, Connection

listen = ['high', 'default', 'low']

redis_url = os.getenv('REDISTOGO_URL')
if not redis_url:
raise RuntimeError('Set up Redis To Go first.')

urlparse.uses_netloc.append('redis')
url = urlparse.urlparse(redis_url)
conn = Redis(host=url.hostname, port=url.port, db=0, password=url.password)

if __name__ == '__main__':
with Connection(conn):
worker = Worker(map(Queue, listen))
worker.work()


A REDISTOGO_URL variable appears in the heroku config.

Redis to go is an installed add-on for my app.

Does REDISTOGO_URL have to be defined in settings.py? Why is heroku trying to connect to the local host when it is not even defined in worker.py?
