- To run on Heroku your app must be configured to use the Postgres database, have all dependencies declared in your Gemfile, and have the rails_12factor gem in the production group of your Gemfile
gem 'rails_12factor', group: :production

gem 'pg' - make sure have

bundle install

- In addition to using the pg gem, you’ll also need to ensure the config/database.yml is using the postgresql adapter.
