Hi Roger,
yes, after you add the same product multiple times and process checkout.
there is a quantity field in the current_item which helps you find that
condition (same book > 2) out.
just to clarify,
you should determine by the quantity of products, instead of number of
orders.
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
Cheers,
Eddie Lau
