3.1 respond_to
When you have two actions that differ primarily in the content type of the returned document, a respond_to refactoring is necessary.
3.1.1 Motive
Methods that differ in the content type of the returned document represent unnecessary duplication in your code. You can extract the common preparatory statements into their own method, but your views and API tools still reference a method that you do not need. Using respond_to you can consolidate these two methods into one, consolidating logic and reducing the number of public actions on your controllers.
