Zend framework 未找到Zend_Db_表关系文件或类

我有两个表，每个表都有课程相册和类别，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');

我收到了这个异常消息。注释掉$user\u cat将不会收到异常消息

我的Albums类在那里，但不知道为什么它说找不到类或文件这是不正确的：

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')
        )
    );

这同样适用于从属关系：

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

并确保

$\u name

属性的值始终与类所代表的表的名称完全相同

[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());

包含

Application\u Model\u DbTable\u Albums

类的文件的名称和路径是什么？它必须是

application/models/DbTable/Alumbs.php

，才能自动加载。这个很有帮助。。感谢RockyFord，但是如何从$user\u cat获取/显示这些结果？
