/store/display_cart/ and it seems items are being added, but if I just

update or alter cart
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

The Depot "Add to Cart" sessions question (2.ed agile book)
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:

Cannot see what I have done wrong.
In the Agile Rails tutorial I am revisiting building a cart. I have
followed the steps given in the book to create the class ''Cart''
thus:
class Cart
attr_reader :items
attr_reader :total_price
def add_product(product)
@items << LineItem.for_product(product)
@total_price += product.price
end
def initialize
@items = []
@total_price = 0.0
end
