Looks like you have two open posts for the same issue... Here is the
answer from the other post...
ahhhh Sorry I see now I was thinking that the CartItem class was an
activerecord class ... The issue is this:
Here you call a new object of CartItem with a product passed
@items << CartItem.new(product)
But here in the initialize you do not have a argument for
initialize...
class CartItem
attr_reader :product, :quantity
def initialize
@product = product
@quantity = 1
end
Change it to this
class CartItem
attr_reader :product, :quantity
def initialize( product )
@product = product
@quantity = 1
end
I would NEVER store the cartitem(add product to cart) in a session
object for a ecommerce application. Yes there are things that could/
should be stored in the session but not something like adding a
product to your cart... Unless you have a session replication system
for your back-end which then would store the session in either the
database or memcache anywho...
