我在agent和Categories两个模型之间有一个HABTM关系。我遵循了这里的说明: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agent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'
)
)
)
只显示来自Agents表的信息，它不显示来自categories表的类别。id是FK。从指令中，我期望类似下面的例子:
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?谢谢你！
您的代理模型应该看起来像:
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' => ''
)
);
}
然后简单地进行如下搜索:
$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。
