Simple respond_with in rails that avoids 204 from PUT

I made a custom responder which always returns my JSON encoded resource even on PUT/POST.

I put this file in lib/responders/json_responder.rb. Your /lib dir should be autoloaded.

module Responders::JsonResponder
  protected

  # simply render the resource even on POST instead of redirecting for ajax
  def api_behavior(error)
    if post?
      display resource, :status => :created
    # render resource instead of 204 no content
    elsif put?
      display resource, :status => :ok
    else
      super
    end
  end
end

Now, explicitly modify the controller which requires this behavior, or place it in the application controller.

class ApplicationController < ActionController::Base

  protect_from_forgery

  responders :json

end

You should now get JSON encoded resources back on PUT.
