在树枝上设置href路径，并在symfony上设置注释路由 - Set href path on twig with annotation route on symfony

Set href path on twig with annotation route on symfony

我正在使用注释路由，我必须设置一个href路径，但我收到此消息

An exception has been thrown during the rendering of a template ("Unable to generate a URL for the named route "crear" as such route does not exist.") in menu.html.twig at line 20.

这是第 20 行的 menu.html.twig

<li><a href="{{ path('crear') }}">Crear</a></li>

这是控制器

<?php
namespace UserBundle'Controller;
use Symfony'Bundle'FrameworkBundle'Controller'Controller;
use Sensio'Bundle'FrameworkExtraBundle'Configuration'Route;
use Symfony'Component'HttpFoundation'Response;
use UserBundle'Entity'User;
use 'DateTime;
class DefaultController extends Controller
{
    /**
     * @Route("/")
     */
    public function indexAction()
    {
        /*$user = new User();
        $user->setUsername("usuario2");
        $user->setFirstName("aaa");
        $user->setLastName("bb");
        $user->setEmail("bbb@mail.com");
        $user->setPassword("123456");
        $user->setRole('ROLE_ADMIN');
        $user->setIsActive(true);
        $user->setCreatedAt(new DateTime());
        $user->setUpdatedAt(new DateTime());
        $em = $this->getDoctrine()->getManager();
        $em->persist($user);
        $em->flush();*/
        return $this->render('UserBundle:Default:index.html.twig');
        //return new Response(phpinfo());
    }
    /**
    *@Route("/ver")
    */
    public function viewAction(){
      $repository = $this->getDoctrine()->getRepository('UserBundle:User');
      $users = $repository->findAll();
      //return new Response($user->getEmail());
      return $this->render('UserBundle:User:view.html.twig',array('users'=>$users ));
    }
    /**
    *@Route("/crear")
    */
    public function createAction(){
      return new Response("Crear");
    }
}

和路由.yml

user:
    resource: "@UserBundle/Controller/"
    type:     annotation
    prefix:   /
app:
    resource: "@AppBundle/Controller/"
    type:     annotation

我必须

激活一些路线或我必须做什么？

您需要指定路由的名称才能通过树枝生成，因此请按如下方式更改控制器注释：

/**
*@Route("/crear", name="crear")
*/
public function createAction(){
  return new Response("Crear");
}
