I had this same problem and I find this really weird because I was using
the actual code supplied by the book and was getting the error. When I
added an extra "end" to the bottom of the file it worked. Can someone
tell me why this code works:
class Cart
attr_reader :items
def initialize
@items = []
end
def add_product(product)
current_item = @items.find {|item| item.product == product}
if current_item
current_item.increment_quantity
else
@items << CartItem.new(product)
end
end
end
It seems to me that there is one too many "end"s here.
Is that right? I am also a newb.
Thanksz!
