CakePHP的2.X：加入在我的模型「MESN」屬於關聯

Question

我有屬於關聯關係：

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 

在我的模型的功能之一，我想加入另一個表的「屬於關聯」，「ShippedBox」 （表格：框）。不過不要緊，我如何努力寫我一起獲得未知列的錯誤消息：

$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 
)); 

我曾嘗試：

'MyShipments.id = ShippedBox.shipment_id' 

和

'MyShipments.id = box.shipment_id' 

甚至

'MyShipments.id = Boxes.shipment_id' 

其中表 「盒子」 W ith字段「shipment_id」存在。

我怎樣才能得到這個工作的加盟？

Answer 1

'MyShipments.id = box.shipment_id' 

到：

'MyShipments.id = Box.shipment_id' 

而且你看這個：

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

））;

的屬於關聯連接是自動完成的。

Answer 2

我認爲你需要做的是這樣使用子查詢得到你想要的東西 -

$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 
));
