Introduction

Adding a new controller action to Rails application

  • Create route in config/routes.rb if needed. Make sure that there is a route that is going to eventually route action, if not create one in routes.rb.
  • Add the action method) in the appropriate app/controllers/*_controller.rb

You have to add the actual code in other words, the method in the appropriate controler file that will do whatever that action is.

  • Ensure there is something for the action to render in app/views/model/action.html.haml. You have to assure that there is something to the action can render what its all done. Every trip through the controller has to end with returning something and will see that although the most common thing is returning a view whose name matches the controller action, we can also return other things.
