I get the feeling you're not really sure how to use Rails.
Whether or not you need a controller for you cart is up to you, however I would have one. That way you can have a "view your cart" page, as well as easily delete items.
原则上,除非你有一个路由,你不应该需要一个控制器Carts
你的config / routes.rb文件内。
Yes, the above method should definitely live inside a controller. The controller should look like this:
