您好
我需要将以下sql查询转换为cakephp find()格式。它自己的查询工作正常,但我需要改变它。
$this->Part->query(
"SELECT `parts`.`id`,`parts`.`part_name`
FROM `parts`
LEFT JOIN (
SELECT `op` . *
FROM `order_parts` AS `op`
WHERE `op`.`order_id` =".$this->Session->read('orderid')."
) AS `vT`
ON ( `parts`.`id` = `vT`.`part_id` )
WHERE `vT`.`part_id` IS NULL"
);
感谢

如果您的关系是订单HABTM部分,并且您有一个表orders_parts,其中包含列:id,order_id,part_id,您应该可以执行以下操作:
首先,获取订单中的部件的ID:
//each Part has one OrdersPart per order
$this->Part->bindModel(array('hasOne' => array('OrdersParts')));
$parts = $this->Part->find('list', array(
'fields' => array('Part.name'),
'conditions' => array(
'OrdersParts.order_id' => $this->Session->read('orderid'),
),
'recursive' => 2
));
现在获取不在订单中的部分:
$this->Part->find('all', array(
'conditions' => array(
"NOT" => array('Part.id' => array_keys($parts))
),
));
