php - 使用 HABTM 查找未显示 CakePHP 中引用表结果的查询

Question

我在两个模型(代理和类别)之间具有 HABTM 关系。我已按照此处的说明进行操作: http://book.cakephp.org/2.0/en/models/associations-linking-models-together.html

我已经设置了表，创建了 FK 等。为了测试是否正在为代理上的查找查询检索类别，我放入了以下调试代码:

debug($this->AgentsCategories->find('all', array(
    'order' => array('Agent.name', 'Agent.address'), 
    'conditions' => array('Agent.id' => '59')
)));

结果数组:

array(
    (int) 0 => array(
        'Agent' => array(
            'id' => '59',
            'name' => 'MUTUAL UNDERWRITERS',
            'address' => 'Waipahu Branch
94-615 Kupuohi St #102
Waipahu, HI 96797',
            'telephone' => '808-688-2222',
            'fax' => '808-688-0769',
            'email' => null,
            'website' => 'http://www.mutualunderwriters.com',
            'island' => '1',
            'modified' => '2014-04-16 15:56:46'
        )
    )
)

仅显示代理表中的信息，不显示类别表中的类别(其中agents.id 为 FK)。根据说明，我期望类似下面的示例:

Array
(
    [Recipe] => Array
        (
            [id] => 2745
            [name] => Chocolate Frosted Sugar Bombs
            [created] => 2007-05-01 10:31:01
            [user_id] => 2346
        )
    [Ingredient] => Array
        (
            [0] => Array
                (
                    [id] => 123
                    [name] => Chocolate
                )
           [1] => Array
                (
                    [id] => 124
                    [name] => Sugar
                )
           [2] => Array
                (
                    [id] => 125
                    [name] => Bombs
                )
        )
)

我做错了什么和/或我应该如何调试这个？谢谢!

您的代理模型应如下所示:

class Agent extends AppModel {
public $hasAndBelongsToMany = array(
    'Category' =>
        array(
            'className' => 'Category',
            'joinTable' => 'agents_categories', //or your table name
            'foreignKey' => 'agent_id',
            'associationForeignKey' => 'category_id',
            'unique' => true,
            'conditions' => '',
            'fields' => '',
            'order' => '',
            'limit' => '',
            'offset' => '',
            'finderQuery' => '',
            'with' => ''
        )
);
}

只需进行搜索即可:

$this->Agent->find('all', array('order' => array('Agent.name', 'Agent.address'), 
                                'conditions' => array('Agent.id' => '59')));

您将得到预期的结果。
