Reading the Agile book there's an excerpt that states:
''Make the Cart class an Active Record object and store cart data in the database. The session would then store the cart object’s id. When a request comes in, we’d extract this id from the session and then load the cart from the database.''
This Cart class had the methods below. It initializes an @items array which contains CartItem objects (which doesn't extends from ActiveRecord). My guess is that this CartItem class should also be changed into an ActiveRecord object eventhough this point is not mentioned on the book. Am I right making this assumption?
Thanks!
class Cart
def initialize @items = end
def add_product(product) current_item = @items.find {|item| item.product == product} if current_item current_item.increment_quantity else current_item = CartItem.new(product) @items << current_item end current_item end
end
