坚持在 onFlush 监听器 symfony

Question

我正在尝试在 onFlush 侦听器中保留一个实体... 这是我的代码：

    public function onFlush(OnFlushEventArgs $args){

    $em = $args->getEntityManager();
    $uow = $em->getUnitOfWork();

    foreach ($uow->getScheduledEntityUpdates() as $entity) {
        switch (true) {
            case $entity instanceof Products:

                $changeset = $uow->getEntityChangeSet($entity);

                foreach($changeset as $column => $change) {
                            $logs = new Logs();
                            $logs->setDate(new DateTime());


                            $em->persist($logs);
                            $classMetadata = $em->getClassMetadata('BddBundle:Logs');
                            $uow->computeChangeSet($classMetadata, $logs);
                        }
                    }
                }
                break;
            default : break;
        }
    }
}

问题是程序块（没有插入数据库的行）和 PHP 说：

PHP 致命错误：applis/vendor/doctrine/orm/lib/Doctrine/ORM/UnitOfWork.php 第 653 行的最大执行时间超过 300 秒，引用者：http://website/

有人有解决方案/方法吗？

编辑 1：

将 $em 更改为 $uow 不会进行任何更改...

             $uow->persist($logs);
                    $classMetadata = $em->getClassMetadata('BddBundle:Logs');
                    $uow->computeChangeSet($classMetadata, $logs);

这会监视User 实体的变化，并将一些数据插入UserLog 实体。根据您的需要进行调整。

use Doctrine\ORM\Event\OnFlushEventArgs;

class UserEntityListener
{
    public function onFlush(OnFlushEventArgs $args)
    {
        $em = $args->getEntityManager();
        $uow = $em->getUnitOfWork();

        foreach ($uow->getScheduledEntityUpdates() as $entity) {
            if ($entity instanceof User) {
                $userLog = new UserLog();
                $userLog->setUserId($entity->getId());
                $userLog->setMessage('onFlush - update at ' . date('d/m/Y H:i:s'));

                $em->persist($userLog);
                // Instead of $em->flush() because we are already in flush process
                $uow->computeChangeSet($em->getClassMetadata(get_class($userLog)), $userLog);
            }
        }
    }
}
