Question

有以下JSON：

{"id":"6","restaurant_menus":[{"restaurant_menu_items":[{"image":null,"title":"1","description":"2","cost":"3"}],"title":"Title"}],"format":"json","action":"update","controller":"restaurants","restaurant":{"id":6}}

我希望Rails通过嵌套的restaurant_menu_items传递id，restaurant_menus，我试着用它来做：

params.require(:restaurant).permit(:id, { restaurant_menus: [:id, :title, { restaurant_menu_items: [:id, :image, :title, :description, :cost] } ] })

但是这段代码只传递了第一个'id'。我该怎么办？

就像这样。

params.require(:restaurant).permit(:id,
                                   restaurant_menus: [
                                       :id,
                                       :title,
                                       restaurant_menu_items: [
                                           :id,
                                           :image,
                                           :title,
                                           :description,
                                           :cost
                                       ]] )

在Rails 4中使用数组的强大参数
