Reduce Application Clutter, Disable Unwanted Rails Generators

Disable rails generators

Rails has some handy generators to help streamline the creation of models, views, controllers, and a bunch of other goodies.

~/dev/kitten_factory $ rails g controller Kittens
  create  app/controllers/kittens_controller.rb
  invoke  erb
  create    app/views/kittens
  invoke  helper
  create    app/helpers/kittens_helper.rb
  invoke  assets
  invoke    coffee
  create      app/assets/javascripts/kittens.js.coffee
  invoke    scss
  create      app/assets/stylesheets/kittens.css.scss

Unfortunately, over time the unused files that are created (and not deleted) add clutter to your application.

~/dev/kitten_factory $ wc -l app/helpers/*
       2 app/helpers/allergies_helper.rb
      14 app/helpers/application_helper.rb
       2 app/helpers/invitations_helper.rb
       # lots of unused helper files
       # ...
       2 app/helpers/trainers_helper.rb
       2 app/helpers/vets_helper.rb
     194 total # 178 lines of unused application code

Luckily with a small adjustment to your application environment we can avoid the generation of unnecessary files.

# config/application.rb
module KittenFactory
  class Application < Rails::Application
    # Disable generation of helpers, javascripts, css, and view specs
    config.generators do |generate|
      generate.helper false
      generate.assets false
      generate.view_specs false
    end

    # ...
end

This allow us to tailor the generators to only create the files we need.

~/dev/kitten_factory $ rails g controller Users
      create  app/controllers/users_controller.rb
      invoke  erb
      create    app/views/users
      invoke  assets
      invoke    scss


If you use [Suspenders](https://github.com/thoughtbot/suspenders/blob/master/lib/suspenders/app_builder.rb#L110-120), this and more will be automatically configured for you.
