Hi,
I have a representer in a rails engine with the following code:

module Tipax::ClientApi
  module GeoLocationRepresenter
    include Roar::JSON

    property :title  
  end
end

and the controller that use representer :

require_dependency "tipax/application_controller"
require "#{Rails.root}/engines/client_api/app/representers/tipax/client_api/geo_location_representer"

module Tipax::ClientApi
  class DataSyncController < ApplicationController
    include Roar::Rails::ControllerAdditions
    respond_to :json
    # include Roar::Rails::ControllerAdditions::Render
    # represents :json, :entity => Tipax::ClientApi::GeoLocationRepresenter

    def get_all_data
      geo_locations = Tipax::GeoLocation.all
      respond_with geo_locations
    end
  end
end

when loading action of controller this error raised.

Hi Abolfazl, I'm sorry to tell you that I don't support this gem anymore, as I find everything about the Rails Way is wrong, even this gem is only a fix on a pile of rubbish. Your problem is an autoloading issue with Rails, which is one of the many reasons I want to get away from Rails as soon as possible.

Try to always use require_dependency instead of require and have a look at Trailblazer, which is my successor to Rails and its mess.
