similar to: Depot - How to change the Store to a Form based application?

Hello, I''m just getting started with Ruby on Rails. Of course, I bought the "Agile Programming..." book. I went through the shopping cart (depot) tutorial without any problem. However, I would like to change the cart so that one can enter a quantity for each item desired. I''m assuming that each item would need to be converted to include a form with the a hidden field

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 tried i.product_id like in the tutorial and i.product.i all of these 2 notation works , but i find the second seems more clean??? isn''t it. Any explanation will be fine Regards

Hello, Im in the process of working my way through the 2.ed of the agile book. As many of you already know, the book goes through the regular development cycle of the Depot application. I have hit a wall when they started talking about the sessions and the exact mechanics of how an item is added to the session. The code looks like this: depot/app/controllers/store_controller: def add_to_cart

I have looked at examples for this. I found a similar example in the Agile Web Dev... book but that didn''t help. Here''s what i am trying to do. A Cart has many line items.
