cakephp保存多个具有许多与saveAll相关的模型

我找了一整天的答案，但还是找不到答案。有人能找出问题所在吗

我的数据关系表如下：

class Client extends AppModel{
public $hasMany = array('Order' => array('className' => 'Order', 'primaryKey' => 'client_id'));
}

class Order extends AppModel {
    public $hasMany = array('OrderItem'=>array('className'=>'OrderItem','primaryKey'=>'order_id'));

}

class OrderItem extends AppModel {
    public $useTable='orderitems';
    public $hasMany = array('OrderItem_Supplement'=> array('className' => 'OrderItem_Supplement', 'primaryKey' => 'orderitem_id'));

}

class OrderItem_Supplement extends AppModel{
    public $useTable = 'orderitem_supplements';
}

这是我想用

saveAll（$This->request->data，array（'deep'=>true））保存的数据的打印文件（）

首先，您的
在模型中的
关系在哪里？表单中似乎有问题，您可以发布此代码吗？您可以发布您正在使用的函数de
saveAll（…）
？
