NoMethodError in Agile Web Devleopment Depot Tutorial
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

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
