Mysql CakePHP2.x：加入belongsto

在我的“mesn”模型中，我有以下关系：

    public $belongsTo = array(
        'Order' => array(
            'className' => 'Order', 'foreignKey' => 'order_id', 'conditions' => '', 'fields' => '', 'order' => ''
        ), 'SaleOrder' => array(
            'className' => 'SaleOrder', 'foreignKey' => 'sale_order_id', 'conditions' => '', 'fields' => '',
            'order' => ''
        ), 'ShippedBox' => array(
            'className' => 'Box', 'foreignKey' => 'shipped_box_id', 'conditions' => '', 'fields' => '',
            'order' => ''
        )
    ); /*     * * hasMany associations** @var array

在我的一个模型函数中，我想加入“belongsto”“ShippedBox”（表：box）上的另一个表。但无论我如何尝试编写连接，我都会收到未知列的错误消息：

$arr_s_result = $this->find('all', array(
  'joins' => array(
    array('table' => 'shipments',
      'alias' => 'MyShipments',
      'type' => 'INNER',
      'conditions' => array(
      'MyShipments.id = ShippedBox.shipment_id'
    )
  )),
  'conditions' => array('Mesn.name' => $arr_search), 'recursive' => 0
));

我试过：

'MyShipments.id = ShippedBox.shipment_id'

及

甚至

'MyShipments.id = Boxes.shipment_id'

其中存在带有“装运id”字段的表格“箱子”

我怎样才能让这个连接工作

'MyShipments.id = box.shipment_id'

致：

还有这个呢：

$arr_s_result = $this->find('all', array(
                              'conditions' => array('Mesn.name' => $arr_search), 'recursive' => 0

)))

belongstojoin是自动完成的。

我想你需要做一些事情，比如使用子查询来获得你想要的-

$arr_s_result = $this->find('all', array(
     'joins' => array(
          array('table' => '(SELECT boxes.id, [enter other fields you need here] FROM shipments JOIN boxes ON boxes.shipment_id = shipments .id)',
          'alias' => 'MyShipments',
          'type' => 'INNER',
          'conditions' => array(
        'Mens.shipped_box_id = MyShipments.id'
       )
    )),
  'conditions' => array('Mesn.name' => $arr_search), 'recursive' => 0
));

也许你不需要加入？As belongsTo是自动完成的吗？我从执行的sql语句中看到的问题是，它在所有连接的开头添加了连接，在这些连接中，框还不“已知”。这是原始查询，但它没有解决框到发货的依赖关系。这是一个很好的解决方案。将测试明天何时返回工作，并给出进一步的评论或接受

$arr_s_result = $this->find('all', array(
                              'conditions' => array('Mesn.name' => $arr_search), 'recursive' => 0

$arr_s_result = $this->find('all', array(
     'joins' => array(
          array('table' => '(SELECT boxes.id, [enter other fields you need here] FROM shipments JOIN boxes ON boxes.shipment_id = shipments .id)',
          'alias' => 'MyShipments',
          'type' => 'INNER',
          'conditions' => array(
        'Mens.shipped_box_id = MyShipments.id'
       )
    )),
  'conditions' => array('Mesn.name' => $arr_search), 'recursive' => 0
));
