Thank you for the response.

Maybe it will be clearer if I will just begin with the symptom.

I am getting an error saying "Couldn't find Itemprice without an ID"

This message comes up even despite the fact that this is my controller:

class ItempriceController < ApplicationController
  def show
    @itemprices = Itemprice.find(params[:ItemSerial])
  end
end


I am not finding Itemprice by id according to the above, but still I get 
this error.

In my view as a test I have the following:

<% @page_title = "#{@itemprices.Price1}" %>
