我在CakePHP应用程序中使用$ this-＆gt; find（'threaded'）并试图在find（HABTM）中引入相关模型。我尝试了几种方法，比如'join'，'recursive'和'contains'都没有运气。我正在使用CakePHP 2.3.6
这是我的（工作）代码。
class EventsController extends AppController {
public function promoters($id = null) {
$options = array('conditions' => array('Event.id' => $id));
$event = $this->Event->find('first', $options);
$this->set('event', $event);
$this->loadModel('EventsPromoter');
$treelistConditions = array(
'conditions' => array(
'event_id' => $id
),
);
$promoterTree = $this->EventsPromoter->find('threaded', $treelistConditions);
$this->set('promoters', $promoterTree);
}
}
这会产生以下数组输出
Array

[0] => Array
(
[EventsPromoter] => Array
(
[id] => 1
[promoter_id] => 1
[event_id] => 1

我一直在努力工作，这似乎是Cake应该能够轻松处理的事情。在此先感谢您的帮助！
答案 0 :(得分：1)
对于我想要完成的事情，我采取了一种略微错误的方法。虽然我仍然认为这应该可以从我的EventsController类中实现，但我选择在EventsPromotersController HABTM类中创建它。使用此方法代码更简单
class EventsPromotersController extends AppController {
public function event($event_id = null) {
$options = array('conditions' => array('event_id' => $event_id));
$promoters = $this->EventsPromoter->find('threaded', $options);
$this->set('promoters', $promoters);
}
}
