Don't forget to rake after deploying to heroku

Deploying your Rails 3 app to heroku (on their Cedar stack)?

Protip

Don't forget to run this command—ya know, just as you would when first running the app locally on your own machine. (Might save you 20 minutes of chin-scratching!)

# Run a rake task on Heroku:
heroku run rake db:migrate

Good times!
