Question

我有两张表，每张表都有Class Albums和Category，如下所示：

class Application_Model_DbTable_Albums extends Zend_Db_Table_Abstract
{

    protected $_name = 'albums';
    private $_custom_message = '';

    protected $_referenceMap = array(
        'CategoryTypes' => array(
            'columns' => array('category_id'),
            'refTableClass' => 'Category',
            'refColumns' => array('id')
        )
    );
}

class Application_Model_DbTable_Category extends Zend_Db_Table_Abstract {

protected $_name = 'category';

protected $_dependentTables = array('Albums');
}

在我的IndexController编辑操作中，我有以下代码：

$category = new Application_Model_DbTable_Category();

$cat_id = $category->find(1);
$cat_3 = $cat_id->current();

$user_cat = $cat_3->findDependentRowset('Albums');

我收到此异常消息。注释掉$ user_cat将不会获得异常消息

我的相册类在那里，但不知道为什么它说无法找到类或文件

首先这是不正确的：

protected $_referenceMap = array(
        'CategoryTypes' => array(
            'columns' => array('category_id'),
            'refTableClass' => 'Category',
            'refColumns' => array('id')
        )
    );

refTableClass需要整个类名，而不是文件名：

protected $_referenceMap = array(
        'CategoryTypes' => array(
            'columns' => array('category_id'),
            'refTableClass' => 'Application_Model_DbTable_Category',
            'refColumns' => array('id')
        )
    );

依赖表格也是如此：

protected $_dependentTables = array('Application_Model_DbTable_Albums');
}

并确保$_name属性的值始终与该类所代表的表的名称完全相同。

<强> [编辑]

$category = new Application_Model_DbTable_Category();

$cat_id = $category->find(1);
$cat_3 = $cat_id->current();
//try
$user_cat = $cat_3->findDependentRowset();
//or
$user_cat = $cat_3->findDependentRowset('Application_Model_DbTable_Albums');
//or
$user_cat = $cat_3->findDependentRowset(new Application_Model_DbTable_Albums());

Zend_Db_Table未找到关系文件或类
