Render without layout when format is JS (needs drying) [duplicate]

Answer 1

Try the new respond_with syntax:

class SomeController < ApplicationController
  respond_to :html, :json

  ...

  def index
    @things = Something.all
    respond_with(@things)
  end

  ...
end

Although it looks like to get it to render without a layout you are back to pretty much what you had before but at least you have elimnated boilerplate in most of your actions. If you are looking for a detailed explanation of respond_with, check out "Crafting Rails Applications" by Jose Valim. Great book!
