Heroku ❤️ Rails

Useless tool for easy deploy Ruby on Rails to Heroku

If you're using continuous deployment with pipelines in Heroku, you won't need this. However if that style doesn't work, then this may allow you to manage databases and deployment with more control but less hassle.


Add this line to your application's Gemfile:

gem 'heroku_rails'

And then execute:

$ bundle

Or install it yourself as:

$ gem install heroku_rails


TODO: Some of these manual configuration steps, would be nicer to make a bit more automatic perhaps by making this a Rails engine. 1) Your database configuration (config/database.yml) needs to have a username if you want to use the db configurations

2) Append load "heroku_rails/tasks/db_drop_all_tables.rake" to the end of Rakefile.

3) Copy templates into codebase:

   cp $(bundle show heroku_rails)/templates/heroku.thor ./lib/tasks
   cp $(bundle show heroku_rails)/templates/heroku_targets.yml ./config

4) update heroku_targets.yml with your staging and production targets. My set up for this is to have staging deploy the local version, but production deploy the origin/master.

  > TODO: more detail

5) You may want to set up a smoke test that your heroku targets are valid

   require "heroku_rails/heroku_targets"

   RSpec.describe "heroku_targets.yml" do
     it "is valid (smoke test)" do 



Deploy the latest with db migrate during maintenance

thor heroku:deploy staging

or without maintenance

thor heroku:deploy staging --no-maintenance

or without migrating

thor heroku:deploy staging --no-migrate

or a specific tag/branch

thor heroku:deploy staging hotfix-branch


Sync a database down from remote to local

thor heroku:sync:grab -f staging
# when it finishes
rake db:drop_all_tables && thor heroku:sync:from_dump -f staging

FYI rake db:drop_all_tables is handy as it doesn't require you to disconnect any running processes from the database.

Copy production db to staging

thor heroku:sync:to staging -f production

NB: this won't work from a staging to a production environment (failsafe)


After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
