如何在CakePHP中找到与HABTM相关的记录的下拉列表？

我想用habtm关系生成一个下拉列表。例如，我有一个名为users的表，另一个名为vehicles和users\u vehicles

我想要的是将车辆分配给x用户，并将其放在下拉列表中。我怎样才能做到这一点

class User extends AppModel { var $hasAndBelongsToMany = array('Vehicle'); }

这是一种方式，可能还有其他几种

$result = $this->User->Vehicle->find('all', array(
    'recursive' => -1,
    'conditions' => array('Ownership.user_id' => 66),
    'fields' => array('Vehicle.*','Ownership.*'),
    'joins' => array(
        array(
            'table' => 'users_vehicles',
            'alias' => 'Ownership',
            'type' => 'LEFT',
            'foreignKey' => false,
            'conditions'=> 'Vehicle.id = Ownership.vehicle_id'
        )
    )
));
$list = Set::combine($result,'{n}.Vehicle.id','{n}.Vehicle.name');
