zend doctrine couldn't find class

Question

Executing in method checkUnique the line $res=$select->fetchArray(); in the following class I get an error which I cannot solve.

I think it is due to the naming conventions zend autoloader

class Twit_Model_Owners extends Twit_Model_BaseOwners {

    function checkUnique($username) {
        $con = Doctrine_Manager::getInstance()->connection();
        $select = $con->createQuery();
        $select->from($this->getTable()->getTableName(), array('loginName'))
                ->where('loginName=?', $username);
        $res=$select->fetchArray();

        if (empty($res)) {
            return true;
        }
        return false;
    }
}

The exception:

Application error

Request Parameters:

array (
  'module' => 'default',
  'controller' => 'auth',
  'action' => 'signup',
  'username' => 'a',
  'password' => 'x',
  'confirmPassword' => 'x',
  'captcha' => 
  array (
    'id' => 'ae5e3ce58bcf69e25ccdbba601029325',
    'input' => 'hen753',
  ),
  'register' => 'Sign up',
)  

I can instantiate models without problem. This is the code i use to generate models:

  Doctrine::generateModelsFromDb('/var/www/twit/application/models', array('zenddb'), array(
            'baseClassesDirectory' => '',
            'classPrefix' => 'Twit_Model_',
            'classPrefixFiles' => false
            ));

Furthermore, if you want, you can visit the sample page here and get the error by yourself here.

似乎Doctrine不想使用$this->getTable()->getTableName()返回的表名，但是我个人不知道该对象的名称（在我的情况下为Twit_Model_Owners）（抽象为好的，但至少应保留查询构建器中表的名称），但我抱怨。
