Rendering caching like traditional action caching but with the functionality of fragment caching.

Add this line to your application's Gemfile:

gem 'rendering_caching'

And then execute:

$ bundle

class ListsController < ApplicationController
  before_action :authenticate

  caches_rendering :index, :show
end

1. Fork it.
2. Create your feature branch (git checkout -b my-new-feature).
3. Commit your changes (git commit -am 'Add some feature').
4. Push to the branch (git push origin my-new-feature).
5. Create a new Pull Request.
