Question

我正在为symfony 2框架工作，我在Controller中调用自定义Action时遇到了问题。我已将我的应用程序连接到数据库（在xampp上），并且对于每个表我都有Entity类。现在我为这个实体之一（GuestController.php）生成一个CRUD控制器（带有教义），我需要在其中创建一个新的Action，然后调用它。这是行动代码：

 /**
 *
 * @Route("/", name="my_action")
 * 
 */
public function customAction() {
    return new Response('<html><body>Hello</body></html>');
}

现在，如果我尝试使用此链接调用它

http://localhost/TEST/web/app_dev.php/guest/guest_search_by_saloon

我获得了

Unable to find Guest entity.

出了什么问题？

这是完整的控制器类

/**
 * Guest controller.
 *
 * @Route("/guest")
 */
class GuestController extends Controller {

/**
 * Lists all Guest entities.
 *
 * @Route("/", name="guest")
 * @Method("GET")
 * @Template()
 */
public function indexAction() {
    $em = $this->getDoctrine()->getManager();

    $entities = $em->getRepository('mainDbBundle:Guest')->findAll();

    return array(
        'entities' => $entities,
    );
}

/**

    $entity = new Guest();

}

这就是日志所说的：

NFO - Matched route "guest_show" (parameters: "_controller": "main\dbBundle\Controller\GuestController::showAction", "id": "guest_search_by_saloon", "_route": "guest_show")

Answer 1

好的，我的猜测是，首先你没有给url打电话给你，因为正如日志所说的那样，showAction()被调用而不是getBySaloonAction()而这与你的错误相关，是完全明智的。

如果您注意到日志错误，则以某种方式将guest_search_by_saloon（字符串）作为id（整数）传递，并使用$id = 'guest_search_by_saloon'运行db查询，这会导致错误。< / p>
