--------------------------------------

             Summary: Unable to perform operations on CIMI::Model
                 Key: DTACLOUD-525
                 URL: https://issues.apache.org/jira/browse/DTACLOUD-525
             Project: DeltaCloud
          Issue Type: Bug
            Reporter: Michal Fojtik
            Assignee: David Lutterkort
            Priority: Blocker


Today Dies found an interesting issue in CIMI::Model vs CIMI::Service:

mock_driver_cimi_methods.rb:

    def systems(credentials, opts={})
      check_credentials(credentials)
      if opts[:id].nil?
        systems = @client.load_all_cimi(:system).map{|sys| CIMI::Model::System.from_json(sys)}
      else
        begin
          systems = [CIMI::Model::System.from_json(@client.load_cimi(:system, opts[:id]))]
        rescue Errno::ENOENT
          return []
        end
      end
      systems.map{|sys| convert_urls(sys, opts[:env])}.flatten
    end

As you can see, this method will return CIMI::Model::System, which is fine if you want to
serialize it directly to JSON/XML. However, this is how we define 'stop' operation in Rabbit:

      action :stop, :with_capability => :stop_system do
        description "Stop specific system."
        param :id,          :string,    :required
        control do
          system = System.find(params[:id], self)
          action = Action.parse(self)
          system.perform(action, self) do |operation|
            no_content_with_status(202) if operation.success?
            # Handle errors using operation.failure?
          end
        end
      end

In this case, "system.perform" will fail with:

undefined method `perform' for #<CIMI::Model::System:0x00000003d154b8>

The .perform() method is defined for CIMI::Service::System. Any clues how to fix this?
