Symfony PHP事件监听器无法正常工作

我有一个用户可以创建订单的系统。创建订单后,应立即使用创建订单的当前用户,创建订单的时间以及其他一些信息更新另一个实体表。

基本上是日志。

这是我的听众课程;

namespace Qi\Bss\BaseBundle\Lib\PurchaseModule;

use Qi\Bss\BaseBundle\Entity\Business\PurchaseModule\PmodLog;
use Qi\Bss\BaseBundle\Entity\Business\PurchaseModule\PmodOrder;

use Doctrine\ORM\Event\LifecycleEventArgs;

/**
 * Class OrderLogger. Purchase Module activity logger.
 */
class OrderLogger
{
    /**
     * Service container
     * @var type 
     */
    private $serviceContainer;

    /**
     * Performs tasks before destruction
     * @ORM\PostPersist
     */
    public function postPersist(LifecycleEventArgs $args)
    {
        $order = $args->getEntity();

        if ($order instanceof PmodOrder) {
            $logRecord = new PmodLog();

            $user = $this->serviceContainer->get('security.token_storage')->getToken()->getUser();

            $logRecord->setCreatedBy($user);
            $logRecord->setAction('Gemaak');
            $logRecord->setCreatedAt(new \DateTime());
            $logRecord->setOrder($order);
            $logRecord->setDepartment($user->getDepartment());
        }
    }

    /**
     * Sets the sales order exporter object
     * @param type $serviceContainer
     */
    public function setServiceContainer($serviceContainer)
    {
        $this->serviceContainer = $serviceContainer;
    }
}

我不知道我做错了什么,并且我的数据库中的日志表没有得到任何更新。

这也是我的服务;

bss.pmod.logger:
    class: Qi\Bss\BaseBundle\Lib\PurchaseModule\OrderLogger
    calls:
    - [ setServiceContainer, [@service_container] ]
    tags:
        - { name: doctrine.event_listener, event: postPersist }

我没有收到错误,订单已完美创建,但日志数据库仍为空。

您是否需要坚持刷新 $logRecord?您可以从$args获得实体经理。

答案 1 :(得分:0)

您可以根据自己的需要进行调整。在某人创建User实体后,通过从UserLog实体插入一些数据来创建新的User实体/记录。

public function createAction()
{
    $user = new User();
    $user->setUsername('username');
    $user->setPassword('password');

    $this->entityManager->persist($user);
    $this->entityManager->flush();
}

    {
        $entity = $args->getEntity();

        if ($entity instanceof User) {
            $log = new UserLog();
            $log->setUserId($entity->getId());
            $log->setMessage('postPersist at ' . date('d/m/Y H:i:s'));

            $em = $args->getEntityManager();
            $em->persist($log);
            $em->flush();
        }
    }
