I am actually following the instructions/code snippets from "Agile Web Development with Rails" and got as far as page 73 where I did ruby script/generate controller Store index, then edited store_controller.rb to class StoreController < ApplicationController def index @products = Product.salable_items end end and product.rb to: def self.salable_items find(:all, :conditions => "date_available <= now()", :order => "date_available desc") en...

Hi I''m very keen to learn RoR and have been following the Agile Web Development with Rails book (first edition). However, I''ve come across a problem which has had me stumped for days now. After following the instructions up to page 85 I have tried testing the code thus far, as suggested, by adding an item to the cart. But I am getting the following error: --

But that should be quite impossible, beacause the cart.rb has a def add_product(product) as we shall see later. I do not understand why it gives me that error. Here is t...
