我正在 cakePHP 中测试 Has And Belongs To Many 关系。这是我的数据库模型:

联系人拥有并属于多个联系人

联系人有一个

因此,我的联系人模型如下所示:

public $hasOne = array(
    'Person'
);
public $hasAndBelongsToMany = array(
    'ContactLinks' => array(
        'className' => 'Contact',
        'joinTable' => 'contacts_contacts',
        'foreignKey' => 'contact_id_1',
        'associationForeignKey' => 'contact_id_2',
    )
);

为了避免使用深度递归值,我使用了可包含的bahavior。这是我的发现:

$data = $this->Contact->find('first', array(
                        'conditions' => array(
                                'Contact.id' => 15
                        ),
                        'contains' => array(
                            'Contact' => array(
                                'Person'
                            ),
                        ),
                    ));

这个请求对我来说很好。由于 Contact hasOne Person,我在 Contact 容器中查找 Person。但是,它不起作用:(

我的结果数组如下所示:

[ContactLinks] => Array
    (
        [0] => Array
            (
                [id] => 56
                [created] => 0000-00-00 00:00:00
                [modified] => 2013-10-31 11:41:28
                [creator_id] => 1
                [modificator_id] => 2
                [type] => person
                [ContactsContact] => Array
                    (
                        [id] => 1
                        [contact_id_1] => 15
                        [contact_id_2] => 56
                        [link_type] => firm
                        [link_description] => Stagiaire
                    )

            )

        [1] => Array
            (
                [id] => 30
                [created] => 0000-00-00 00:00:00
                [modified] => 0000-00-00 00:00:00
                [creator_id] => 1
                [modificator_id] => 
                [type] => person
                [ContactsContact] => Array
                    (
                        [id] => 2
                        [contact_id_1] => 15
                        [contact_id_2] => 30
                        [link_type] => 
                        [link_description] => Patron
                    )

            )

    )

似乎 CakePHP 没有在 Contact 和 Person 之间建立联系。

关于如何解决这个问题的任何想法?

谢谢 !

我认为使用错误的别名时会出现问题。尝试这个

$data = $this->Contact->find('first', array(
  'conditions' => array(
  'Contact.id' => 15
 ),
'contains' => array(
 'ContactLinks' => array('Person'))
));

编辑:错字警报->“包含”应该是“包含”

$data = $this->Contact->find('first', array(
  'conditions' => array(
  'Contact.id' => 15
 ),
'contain' => array(
 'ContactLinks' => array('Person'))
));
