看到這邊覺得很困惑， 看起來 form 有設一個參數 quantity 1,2,3,4,5 給 user選
但是送出之後 看起來是會往 checkout_carts_path 丟過去
但是我去看 carts controller 裡面的 checkout action 裡面好像沒有處理選擇的數字...
實際上畫面操作的時候 看起來後台也是當作是 數量 1 在計算..
不知道是否是這邊尚未寫完? 因為寫作業時 這邊卡很久, 所以很想知道怎麼解決
thanks

form_for 好像會依照給的path來決定是post(create)或patch(update)
是對著cart_item_path丟值的
可以在那頁按右鍵看原始碼，會看到patch
http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#method-i-form_for-label-Resource-oriented+style
<%= link_to cart_item_path(current_cart, item), :method => :delete do %>
似乎也沒有傳值，是在controller另外從session或cache要資料的
（有錯請指正XD）
