在CakePHP 2.5.x中的第二级关联中应用where条件

Question

我想在cakephp中为我的第二级关联添加一个where子句。根据我的理解，这应该有效，但它给了我一个错误

错误：[PDOException] SQLSTATE [42S22]：找不到列：1054'where子句'中的未知列'User.email_address'。

$options = array(
    'contain' => array(
        'People',
        'People' => array('User')
    ),
    'conditions'=> array(
        'User.email_address' => 'sample@mail.com'
    ), 
    'recursive' =>1,
);
$query = $this->Organization->find('all', $options);

Answer 1

$options = array(
    'contain' => array(
        'People' => array(
            'User' => array(
                'conditions'=> array(
                    'User.email_address' => 'sample@mail.com'
                ),
            ),
        ),
    ),
    //'recursive' =>1,
);
$query = $this->Organization->find('all', $options);
