Question

我想以这种方式保存数据：'订单' - ＆gt;'OrdersFoods' - ＆gt;'OrdersFoodsChanges'。 OrdersFoodsTable是一个连接表（订单 - 食品）。

为什么我要这样做？ Table OrdersFoods包含有关订购食品（ID）的信息，但我想以特定顺序保存有关该食品所用每种成分的其他数据。这就是为什么我从表OrdersFoods创建了具有id的附加表（OrdersFoodsChanges）。

我可以将数据保存到连接表，但不能保存到另一个表（OrdersFoodsChangesTable）。

我尝试过最简单的方法：

            $order = $this->Orders->patchEntity($order, $this->request->data, [
            'associated' => [
                'Foods._joinData.OrdersFoodsChanges'
                //'Foods.OrdersFoods.OrdersFoodsChanges'
            ]

但没有运气。

正如我从sql log中看到的那样，Cake甚至没有尝试将任何东西保存到最后一个表中。

如果有任何帮助，我将不胜感激。

Answer 1

所以主要问题是默认情况下，蛋糕保存方法只能进行一级关联。

默认情况下，save（）方法还会保存一个关联级别

当我添加相关内容时，一切顺利。

        if ($this->Orders->save($order, [
            'associated' => ['Foods._joinData.OrdersFoodsChanges']
        ]))

Cakephp 3将数据保存到连接表和与该连接表关联的表
