Php Symfony3-“；“无法识别的字段”；基于多对一关系属性的值提取条目时出现异常

我希望显示实体中的记录，但仅显示loginID值等于当前用户ID的记录。在事件实体中，loginID是多对一属性。

我有以下事件：

以及控制器中的以下索引操作：

namespace Vendor\MyBundle\Controller;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Vendor\MyBundle\Entity\Events;
use Vendor\MyBundle\Form\EventsType;

/**
 * Events controller.
 *
 * @Route("/sec/events")
 */
class EventsController extends Controller
{
    /**
     * Lists all Events entities.
     *
     * @Route("/", name="sec_events_index")
     * @Method("GET")
     */
    public function indexAction()
    {
        $em = $this->getDoctrine()->getManager();
        $user = $this->getUser();
        $events = $em->getRepository('VendorMyBundle:Events')->findBy(array('loginid' => $user->getLoginid()));

        return $this->render('events/index.html.twig', array(
            'events' => $events,
        ));
    }
}

但是，我被抛出错误：Unrecognized field:loginid，即使这是Events类中字段/属性的名称
我看了一下，我确实有代码，就像上面说的那样
我错过了什么？

任何帮助都将不胜感激

您缺少

$loginid

的一些ORM定义，因此事件表中没有列loginid

---

我假设您希望与

..\Entity\Logins

有一个多域或多个关联，因此您必须根据以下内容定义该关联：

小建议-在类中首先组织属性，然后组织方法。它更好，可读性更好，将来你会喜欢它的。谢谢，说得好。当我回到那个班时，我总是把它们弄丢是的，就是这样！谢谢
至于OneToMany，我不能添加它，我也不需要它，因为目标实体中的目标属性是ID属性，它不允许我在注释中添加该选项，对吗？简单地说-如果您不为属性定义ORM注释，它对原则是不可见的，并且该属性不会持久化到DB中（不管是简单的数据类型还是关联）。然后，当您想要在VendorMyBundle:Events repo中获取loginid时，没有任何选项…您必须选择-1）根据您的需要定义一些关联，2）如果您不想要关联，您必须手动设置$loginid，但在stat情况下，它必须与Logins类中的$id类型相同
