Many of you probably know the ''depot'' app from the ''Agile Rails development'' book. When the view changes from ''Store'' to ''display_cart,'' a session containing the shopping-cart (:cart) is supposed maintain the ''cart'' between calls, but when the display_cart stub view shows up, I have always ZERO elements in the cart! I have received valuable help already, but the issue seems less understandable tha...

I''m working my way through the book Agile Web Development with Rails, and I am in the section where the book has me creating a display_cart method and the associated view.

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 Store#add_to_cart #{RAILS_ROOT}/app/models/cart.rb:10:in `add_product'' #{RAILS_ROOT}/app/controllers/store_controller.rb:11:in `add_to_cart'...

In other words, shouldn''t it be :id => product.id ? I don''t understand why the whole product object is being hashed when the find method is only going to use the id value anyway. Thanks David...

I want to modify and update the items in the Depot - "display_cart". Since the cart is in a session, its a little hard to get at the data. I just want to create a way to change quantities, prices and recalculate. Has someone done this, and could you point me to the right direction. Thanks Chas -- Posted via http://www.ruby-forum.com/.

Hi I am new to the whole Rails/Ruby world as having come from a MS .NET background, but I have followed the Depot example in the Agile Web Dev. with Rails book with relative ease. However as an exercise to see how much I had understood, I thought I would attempt to modify the example a bit and add a Quantity field to the store index so as to pass that value into the cart. I have extended the
