Question

如何在控制器外的类中使用Doctrine？

$event = $this->getDoctrine()
    ->getRepository('AtotrukisMainBundle:Event')
    ->findByCreatedBy($userId);
if (!$event) {
    throw $this->createNotFoundException(
        'You have no events'
    );
}

上面的代码在控制器中完美运行，但在服务中我收到错误：Attempted to call method "getDoctrine" on class "Atotrukis\MainBundle\Service\EventService" in /var/www/src/Atotrukis/MainBundle/Service/EventService.php line 15.

如何让它发挥作用？

services.yml：

services:
    eventService:
        class: Atotrukis\MainBundle\Service\EventService

来自EventController的部分：

public function readMyEventsAction()
{
    $user = $this->getDoctrine()->getRepository('AtotrukisMainBundle:User')
        ->findOneById($this->get('security.context')->getToken()->getUser()->getId());

    $userEvents = $this->get('eventService')->readUserEvents($user);

    return $this->render('AtotrukisMainBundle:Event:myEvents.html.twig', array('events' => $userEvents));
}

EventService.php：

<?php
namespace Atotrukis\MainBundle\Service;

class EventService{

    public function create(){


    }
    public function readUserEvents($userId){

        $event = $this->getDoctrine()
            ->getRepository('AtotrukisMainBundle:Event')
            ->findByCreatedBy($userId);
        if (!$event) {
            throw $this->createNotFoundException(
                'You have no events'
            );
        }
        return $userId;
    }

}

您可以在服务声明中将其作为参数传递：

services:
    eventService:
        class: Atotrukis\MainBundle\Service\EventService
        arguments: ["@doctrine.orm.entity_manager"]

然后只需在你的类中添加一个构造函数：

protected $em;

public function __construct($em)
{
    $this->em = $em
}

在服务Symfony2中使用Doctrine
