Question

有没有办法在symfony2中使用实体管理器（doctrine）手动指定事务，或者可能是在单个事务中完成的自然方式，我在下面做两个事情？

// creating screen object...
//Creating user object...

        //flush the screen into database in order to get the Id to relate the server (user) to
        $em->persist($screen);
        $em->flush();

        //Get id of just inserted screen and attach that to new server (user)
        $tempRecordId = $screen->getId();
        $tempEntity = $em->getRepository('BizTVContainerManagementBundle:Container')->find($tempRecordId);
        $entity->setScreen($tempEntity);

        //Flush the user also into database
        $em->persist($entity);
        $em->flush();

请参阅我必须刷新我的第一个实体以获取它的ID，所以我可以将我的第二个实体与我的第一个实体联系起来......

Answer 1

try {
    $em->getConnection()->beginTransaction();

    // do your thing here

    $em->getConnection()->commit();
} catch (\Exception $e) {
    $em->getConnection()->rollback();
    throw $e;
}

Answer 2

你为什么不这样做：

// creating screen object...
//Creating user object...
    $entity->setScreen($screen);
    $em->persist($screen);
    $em->persist($entity);
    $em->flush();
