If you've manage to generate the app, all you should need is Postgres.app.
The version expected is Postgres93.app. If a different version is used, the
rake command in lib/tasks/development.rake will need to be updated to use
the rake start command.
A rake command is included to start up Postgres.app if it isn't running already and then start the Rails app with Puma at http://localhost:3000.
$ rake startThis app is made to be deployed to Heroku
and should work out of the box as long as the environment variables
from .env are set on Heroku using heroku config:set VARIABLE_NAME=VALUE.
