向生成的控制器添加新的普通操作：找不到对象

时间：2016-10-18 15:01:24

标签： symfony

我刚刚使用DefaultBundle生成了一个包（Manufacturer），一个实体（php bin/console generate:doctrine:crud --entity=DefaultBundle:Manufacturer）及其CRUD控制器。

问题：

当我尝试向生成的控制器添加新操作时，如下所示：

/**
 * @Route("/search", name="manufacturer_search")
 * @Method({"GET"})
 */
public function searchAction() 
{
    return new Response("foobar");
}

并请求app_dev.php/manufacturer/search，我收到此错误：

  

找不到DefaultBundle \ Entity \ Manufacturer对象。 404未找到 -   NotFoundHttpException

这是空心控制器：

?php

namespace DefaultBundle\Controller;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use DefaultBundle\Entity\Manufacturer;
use DefaultBundle\Form\ManufacturerType;

/**

 * @Route("/manufacturer")
 */
class ManufacturerController extends Controller
{
    /**
     * Lists all Manufacturer entities.
     *
     * @Route("/", name="manufacturer_index")
     * @Method("GET")
     */
    public function indexAction()
    {
        $em = $this->getDoctrine()->getManager();

        $manufacturers = $em->getRepository('DefaultBundle:Manufacturer')->findAll();

        return $this->render('manufacturer/index.html.twig', array(
            'manufacturers' => $manufacturers,
        ));
    }

    /**

        if ($form->isSubmitted() && $form->isValid()) {
            $em = $this->getDoctrine()->getManager();
            $em->persist($manufacturer);
            $em->flush();

            return $this->redirectToRoute('manufacturer_show', array('id' => $manufacturer->getId()));
        }

        return $this->render('manufacturer/new.html.twig', array(
            'manufacturer' => $manufacturer,
            'form' => $form->createView(),

    }

    /**

    {
        $deleteForm = $this->createDeleteForm($manufacturer);

    public function editAction(Request $request, Manufacturer $manufacturer)
    {
        $deleteForm = $this->createDeleteForm($manufacturer);
        $editForm = $this->createForm('DefaultBundle\Form\ManufacturerType', $manufacturer);
        $editForm->handleRequest($request);

        if ($editForm->isSubmitted() && $editForm->isValid()) {
            $em = $this->getDoctrine()->getManager();
            $em->persist($manufacturer);
            $em->flush();

            return $this->redirectToRoute('manufacturer_edit', array('id' => $manufacturer->getId()));
        }

        return $this->render('manufacturer/edit.html.twig', array(
            'manufacturer' => $manufacturer,
            'edit_form' => $editForm->createView(),
            'delete_form' => $deleteForm->createView(),
        ));
    }

    /**

     *

     */
    public function deleteAction(Request $request, Manufacturer $manufacturer)
    {
        $form = $this->createDeleteForm($manufacturer);
        $form->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()) {
            $em = $this->getDoctrine()->getManager();
            $em->remove($manufacturer);
            $em->flush();
        }

        return $this->redirectToRoute('manufacturer_index');
    }

    /**
     * Creates a form to delete a Manufacturer entity.
     *
     * @param Manufacturer $manufacturer The Manufacturer entity
     *
     * @return \Symfony\Component\Form\Form The form
     */
    private function createDeleteForm(Manufacturer $manufacturer)
    {
        return $this->createFormBuilder()
            ->setAction($this->generateUrl('manufacturer_delete', array('id' => $manufacturer->getId())))
            ->setMethod('DELETE')
            ->getForm()
        ;
    }

    /**
     * @Route("/search", name="manufacturer_search")
     * @Method({"GET"})
     */
    public function searchAction() 
    {
        return new Response("foobar");
    }
}

这是路径和Manufacturer实体。 enter image description here enter image description here

3 个答案:

答案 0 :(得分：0)

请求网址不应该是：

app_dev.php/search

从您的代码中看起来就是这样。我不确定这是否正确，但你可以试试吗？

答案 1 :(得分：0)

在symfony的调试工具栏中，我注意到请求的路由是manufacturer_show。所以我刚刚删除了相应的操作，因为我没有使用它，现在当我请求我在我的问题（manufacturer/search）中提到的URL时，我到达了刚刚创建的操作（searchAction）

答案 2 :(得分：0)

您的搜索操作需要在您的展示操作之前进行。 Symfony按顺序编译路线。因为您的展示模式"/{id}"基本上匹配斜杠"/search"之后的任何内容，例如，您的搜索方法将无法访问。

但是，如果您将搜索方法移到show方法之上并清除缓存，则路由将按预期工作。

请注意，这也意味着您可以拥有任何＆＃34; id＆＃34;＆，其值为＆＃34;搜索＆＃34;或者他们不匹配
