How can i fix this?
Well, one way would be to ensure that @items was always an array before you get to your view, but if you just want to deal with it in the view do:
Your cart contains <%= @items.nil? ? "no items" : pluralize(@items.size, "item")) %>.
WHich would result in:
no items 1 item 2 items
depending on if there are no, 1, or 2 (or more) items in the cart.
