Question

我需要同时更新卡片模型的所有记录。我使用map函数获取每张卡的数据，然后使用和AJAX请求发送数据。

var cards = ui.item.parent('.js-CardsContainer .js-CardContainer').map(function() {
    return {
        list_id: $(this).closest('.js-List').data('id'),
        order: $(this).index
    }
}).get();

$.ajax({
    url: "/cards/",
    type: "PATCH",
    data: { cards: cards },
    success: function(resp){
    }
});

我不知道如何使用rails处理这些数据。我的卡片控制器中的哪个动作可以放入逻辑？这个逻辑应该是什么样的？

我想我需要这样的东西......

def index
    cards.each(&:save!)
end

显然这是不正确的。有人可以帮忙吗？

以下是发送数据时的日志输出：
