Hi all, on page 151 of the book agile... we have the following code in the file order.rb: def add_line_items_from_cart(cart) cart.items.each do |item| li = LineItem.from_cart_item(item) line_items << li end what kind of variable is line_items? is it a local, class, instance or other kind of variable? if it is local how rails saves the contents of this variable when saves the order in "save_order" method which is place in the file "store_controller.rb"?

Assuming the code is correct (you're missing an 'end' for starters), the only way this could work were if line_items were a method returning an appropriate object. Fred
