This generator is here to speed up the process of you writing boilercode for your rest-api Rails app.

This generator is highly opinionated. It creates files that fit the way I manage my files and directories inside a Rails project. Also, it assumes you are using: rspec, dry-validation, use cases pattern and presenter pattern.


Add this line to your application's Gemfile:

group :development do
  gem 'rails-api-controller-generator'

And then execute:

$ bundle


In your project root folder execute:

$ bundle exec rails generate api_controller model_name action1 action2

So for example running:

$ bundle exec rails generate api_controller post index create

will create following files:

  • app/controllers/api/v1/posts_controller.rb
  • app/schemas/posts_index_schema.rb
  • app/use_cases/posts/index.rb
  • app/schemas/posts_create_schema.rb
  • app/use_cases/posts/create.rb
  • app/presenters/post_presenter.rb
  • app/presenters/posts_presenter.rb
  • spec/requests/posts_spec.rb

Each of these files will be filled with code. Model name needs to be singular!


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.
