我的DAO类怎么能看到我的学说模型

我已经决定将所有DAO操作从我的控制器类移动到DAO类(刚刚在java上习惯了)。

无论如何，当我试图运行我的DQL，学说是抱怨它不能看到我的模型/实体。但我认为在DAO类的顶部声明它可以防止这种情况。显然不是。

你能帮帮我吗?由于

my DAO class

<?php
namespace Directory'Dao;
use Directory'Model'DirectoryModel;
use Doctrine'ORM'QueryBuilder,
    Doctrine'ORM'Query'Expr'Andx;
class DirectoryDao {
    /**
     * @var Doctrine'ORM'EntityManager
     */
    protected $entityManager;
    public function setEntityManager(EntityManager $entityManager) {
        $this->entityManager = $entityManager;
    }
    public function getEntityManager() {
        if (null === $this->entityManager) {
            $this->entityManager = $this->getServiceLocator()->get('Doctrine'ORM'EntityManager');
        }
        return $this->entityManager;
    }
    public function searchStaffDirectory(QueryBuilder $queryBuilder, DirectoryModel $directory) {
        //$queryBuilder = $this->getEntityManager()->createQueryBuilder();
        $conditions = new Andx;
        $queryBuilder
                ->select('directory')
                ->from('DirectoryModel', 'directory');
        if (strlen($directory->surnameSearch)) {
             $conditions->add($queryBuilder->expr()->like('directory.surnameSearch', $directory->surnameSearch));
        }
        if (strlen($directory->surnameSoundsSearch)) {
             $conditions->add($queryBuilder->expr()->like('directory.surnameSoundsSearch', $directory->surnameSoundsSearch));
        }
        if (strlen($directory->firstnameSearch)) {
             $conditions->add($queryBuilder->expr()->like('directory.firsnameSearch', $directory->firstnameSearch));
        }
        if (strlen($directory->telephoneNumber)) {
             $conditions->add($queryBuilder->expr()->like('directory.telephoneNumber', $directory->telephoneNumber));
        }
        if (strlen($directory->departmentSearch)) {
             $conditions->add($queryBuilder->expr()->like('directory.departmentSearch', $directory->departmentSearch));
        }
        if (strlen($directory->roleSearch)) {
             $conditions->add($queryBuilder->expr()->like('directory.roleSearch', $directory->roleSearch));
        }
        if ($conditions->count()) {
                $queryBuilder->andWhere($conditions);
        }
        $queryBuilder
                ->orderBy('UPPER(directory.surname)')
                ->addOrderBy('UPPER(directory.firstname)');
        $query = $queryBuilder->getQuery();
        $result = $query->getResult();

        var_dump($queryBuilder->getDql());
    }
}
