I am really new to Ruby and Rails but as you probably see I am trying
to get the shopping card working from the book. I am getting this
error but I really don't know what to do. I have looked up several of
topics that stated the same problem but as far as I am, nothing has
helped me out yet. Is there something wrong with the Product model?
This is in the StoreController and I believe it is all good.
@cart = find_cart
product = Product.find(params[:id])
Thanks in advance
