- # can trigger special behavior (as in the case of +observer+), and enables Rails to be clever about reloading in cached environments

- #
- # class ApplicationController < ActionController::Base
- # model :account, :company, :person, :project, :category
- # helper :access_control
- # service :notifications, :billings
- # observer :project_change_observer

- # Please note that a controller like ApplicationController will automatically attempt to require_dependency on a model of its
- # singuralized name and a helper of its name. If nothing is found, no error is raised. This is especially useful for concrete
- # controllers like PostController:
- #
- # class PostController < ApplicationController
- # # model :post (already required)
- # # helper :post (already required)
- # end

- # Also note, that if the models follow the pattern of just 1 class per file in the form of MyClass => my_class.rb, then these
- # classes don't have to be required as Active Support will auto-require them.
