使用symfony2从数据库导出.csv

我没有让这种方法起作用,也许有人有想法。

/**
 * @Route("/export", name="export")
 * @Template("AppBundle:Expenses:export.html.twig")
 */
public function exportAction()
{

    $repository = $this->getDoctrine()->getRepository('AppBundle:Expenses');

    $query = $repository->createQueryBuilder('s');
    $query->orderBy('s.id', 'DESC');

    $data = $query->getQuery()->getResult(); $filename = "export_".date("Y_m_d_His").".csv";

    $response = $this->render('AppBundle:Expenses:export.html.twig', array('data' => $data));

    $response->setStatusCode(200);
    $response->headers->set('Content-Type', 'text/csv');
    $response->headers->set('Content-Description', 'Submissions Export');
    $response->headers->set('Content-Disposition', 'attachment; filename='.$filename);
    $response->headers->set('Content-Transfer-Encoding', 'binary');
    $response->headers->set('Pragma', 'no-cache');
    $response->headers->set('Expires', '0');

    return $response;
}

我得到了:

Unable to find Expenses entity.
404 Not Found - NotFoundHttpException

有趣的事情: 在另一种方法中,这是有效的:

$entity = $em->getRepository('AppBundle:Expenses')->find($id);

所以,AppBundle下确实有一个费用实体。错误来自哪里?
