Hi All,

I am using AWS to implement web service APIs in rails and i am using Layered dispatching mode for implementation.

Here i am not getting how can i use controller's instance methods (both user defined and built in) inside my API service.

As an example below take below things in consideration.

this is API signature.

class ProductApi < ActionWebService::API::Base

     api_method :find_all_products,      :returns => [[:int]]

    api_method :find_product_by_id,     :expects => [:int],      :returns => [Product] end

this is layered_backend controller.

class LayeredBackendController < ApplicationController

      dispatching_web_service_mode :layered       web_service_scaffold :invoke       web_service(:order) { OrderService.new }

      def test_method          # some code       end end

this is order_service.rb file.

class OrderService< ActionWebService::Base      web_service_api ProductApi

     def find_all_products          Product.find(:all).map{ |product| product.id }      end

     def find_product_by_id(id)          Product.find(id)      end end

Now if i want to use my controller instance method named test_method inside OrderServie then how can i use it ?

and also how to use controller built in instance methods (like session, log_error etc )inside OrderService ?

Thanks in Advance.

Piyush.
