SF Homelessness Twitter Listener using Flask, Cloudant, tweepy, gunicorn, and Heroku.

Based on the repo at flask_listen. Follow the installation instructions there.

Cloudant and Twitter credentials

You need an account on Cloudant and Twitter. Per Heroku's configuration recommendations, set the following keys in a .env file:

CLOUDANT_USER=...
CLOUDANT_PASS=...
CLOUDANT_DB=...
TWITTER_CONSUMER_KEY=...
TWITTER_CONSUMER_SECRET=...
TWITTER_ACCESS_KEY=...
TWITTER_ACCESS_SECRET=...

To get this onto Heroku:

heroku create {name of Heroku instance}
heroku config:push
git push heroku master

This might help: http://stackoverflow.com/questions/27899517/heroku-configpush-not-adding-environment-variables

Then, to start the listener, enter this:

heroku ps:scale worker=1

The worker runs listen.py to stream tweets into Cloudant.

To get TextBlob working on Heroku with Flask, the answer at the bottom of the page worked great!
