Rails with_options

Rails has a convenient method with_options for reusing options on rails methods.

On the documentation we can see how to use on ActiveRecord classes but as this method is under Rails Object it actually can be used on several other places, like controllers.

Check this out:

before with_options

class PostsController < ApplicationController
  before_action :require_login, only: [:show, :edit]
  before_action :load_post_extra_info, only: [:show, :edit]

  ...
end

using with_options

class PostsController < ApplicationController
  with_options only: [:show, :edit] do
    before_action :require_login
    before_action :load_post_extra_info
  end

  ...
end

Thanks @mattpolito for that!
