学说跟踪多个实体关系的变化

Question

我有这个实体

class nmEntidad
{

/**

private $id;

 * @ORM\Column(name="eliminado", type="boolean")
 **/
private $eliminado;

/**

 **/
private $tieneArea;

/**

 *
 * @ORM\Column(name="tiene_entidad", type="integer")
 **/
private $tieneEntidad;

/**

 */
private $representante;

然后我有一个doctrine lifecyclecallback事件的监听器，所以每当这些事件中的一个触发时，我都会为asociated事件创建一个登录数据库。

 public function onSucessLogin(AuthenticationEvent $event)
{
    if (!$event->getAuthenticationToken()->getUser() instanceof UserInterface)
        return;
    if(!$this->request)
        return;
    if ($this->request->getMethod() == 'GET')
        return;
    $user = $event->getAuthenticationToken()->getUser();
    $this->container->get('monolog.logger.db')->info('request', ['user' => $user->getUsername(), 'empresa' => $user->getEmpresa()->getEmpresa()]);

}


//establecemos el codigo de response para ver si fallo la operacion o no
public function onKernelResponse(FilterResponseEvent $event)
{
    if (!$this->checkIfUserRequest())
        return;
    if (!$this->isLog())
        return;
    if (!$event->isMasterRequest())
        return;


    $responseCode = $event->getResponse()->getStatusCode();
    if (!$this->request->attributes->has('logEntry'))
        return;
    $logEntry = $this->request->attributes->get('logEntry');
    if ($responseCode == Response::HTTP_BAD_REQUEST) {
        $logEntry['status'] = Response::HTTP_BAD_REQUEST;
    } else if ($responseCode == Response::HTTP_FORBIDDEN) {
        $logEntry['status'] = Response::HTTP_FORBIDDEN;
    } else if ($responseCode == Response::HTTP_UNAUTHORIZED) {
        $logEntry['status'] = Response::HTTP_UNAUTHORIZED;
    }

这适用于实体的简单值，例如名称地址等，但是当@manytoone或@manytomany带注释的属性发生更改时，例如，侦听器的preupdate方法不会触发。是否有这种属性的额外配置或我遗漏了什么？

对于Collection，您可以使用：

$uow->getScheduledCollectionUpdates();
$uow->getScheduledCollectionDeletions();

如果它是PersistentCollection，您可以检索原始数据：

$entity->getSnapshot()
