左CakePHP的自定义查询连接表的行为嵌套数组

Question

我试图让下面我CakePHP的自定义查询嵌套数组：

$this->query(" 
       SELECT * 
       FROM group_buys GroupBuy 
       LEFT JOIN products Product 
       ON Product.id = GroupBuy.product_id 
       LEFT JOIN group_buy_users GroupBuysUser 
       ON GroupBuysUser.group_buy_id = GroupBuy.id 
       LEFT JOIN group_buy_images GroupBuyImage 
       ON GroupBuyImage.group_buy_id = GroupBuy.id 
       LEFT JOIN product_details ProductDetail 
       ON ProductDetail.product_id = Product.id 
       LEFT JOIN specifications Specification 
       ON Specification.id = ProductDetail.specification_id 
       LEFT JOIN specification_categories SpecificationCategory 
       ON SpecificationCategory.id = Specification.specification_category_id 
       WHERE GroupBuy.id = {$id} 
      "); 

问题的，这是它与冗余数据明显与团购来了表行值重复我不想要的。

有没有一种方法，我们可以有嵌套数组，如果LEFT JOINED表中有更多的行比以前的表与Cake的自定义查询？

我知道这可以用find recursive = 2来完成，但是想用自定义查询来实现。

您是否尝试过使用可容纳？

$this->GroupBuy->Behaviors->attach('Containable'); 

$this->GroupBuy->find('all', array(
    'conditions' => array('GroupBuy.id' => $id), 
    'contain' => array(
     'Product' => array(
      'ProductDetail' => array(
       'Specification' => array(
        'SpecificationCategory' 
       ) 
      ) 
     ), 
     'GroupBuysUser', 
     'GroupBuyImage' 
    ), 
));
