I''m working on building the shopping cart in the Depot tutorial in the Agile Web Development book. I''m at the part (about page 80) where you build the ability to add items to the cart. I''m able to get to /store/display_cart/ and it seems items are being added, but if I just click on a link to add an item (/store/add_to_cart/2) it gives me this: NoMethodError in

In the Agile Rails tutorial I am revisiting building a cart.
