In their StoreController class they define a find_cart method as: [code] def find_cart @cart = (session[:cart] ||= Cart.new) end [/code] Whether this has any applicability to your case is impossible to know without knowing a lot more about your application. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
