Doctrine查询错误unknow列

Question

我在Symfony3项目中使用Doctrine。我正在使用实体管理器从数据库中获取数据，但我有一个意外的错误，似乎是由学说产生的。

  

在渲染模板期间抛出异常（“执行'SELECT t0.id AS id_1时发生异常，t0.date AS date_2，t0.comment AS comment_3，t0.viewed AS seen_4，t0.error_count AS error_count_5，t0.of_id AS of_id_6，t0.checkpoint_id AS checkpoint_id_7，t8.id AS id_9，t8.name AS name_10，t8.description AS description_11，t8.deleted_at AS deleted_at_12，t8.factory_id AS factory_id_13，t0.operateur_id AS operateur_id_15 ，t0.factory_id AS factory_id_16 FROM app_check_set t0 LEFT JOIN app_checkpoint t8 ON t0.checkpoint_id = t14.id AND（（t14.deleted_at IS NULL））WHERE t0.factory_id =？ORDER BY t0.date DESC LIMIT 5'with params [3 ]：

SQLSTATE [42S22]：未找到列：1054'on clause'中的未知列't14.id'“）。

由于我不是自己创建查询，我想知道这个错误来自哪里？它与我的实体配置有关吗？

问题在于我想获取我的实体Checkset：

public function notificationsAction(Request $request){
    $user           = $this->getUser();
    $em             = $this->getDoctrine()->getManager();

    return $this->render('AppBundle:Home:notifications.html.twig', array(
        'notifications' => $em->getRepository('AppBundle:CheckSet')->findBy(array('factory' => $user->getFactory()->getId()), array('date' => 'desc'), 5),
        'count'         => count($em->getRepository('AppBundle:CheckSet')->findBy(array('factory' => $user->getFactory()->getId(), 'viewed' => false)))
    ));
}

我的实体是这样的：

问题可能是因为软删除但我不确定......我正在调用的控制器（notificationsAction）嵌入我的标题中。

在此页面（通知区域）中，我想显示可能已被删除的对象。我想要显示的checkpoint（与Checkset对象相关的那个）已被删除时发生的问题

<!-- NOTIFICATIONS -->
{{ render(controller('AppBundle:Home:notifications', {'request': app.request})) }}

Answer 1

您的问题实际上与here相同。

您的班级名称是检查点，我想该文件名为 checkpoint.php （请注意，如果您在Windows上开发，则文件名不区分大小写）。所有都是小写。

在你的CheckSet类中有

/**
 * @ORM\ManyToOne(targetEntity="AppBundle\Entity\CheckPoint", inversedBy="checkSet", fetch="EAGER") 
 * @ORM\JoinColumn(name="checkpoint_id", referencedColumnName="id")
 */
private $checkPoint;

targetEntity 是“AppBundle \ Entity \ CheckPoint”，资本 P 。

问题在于，因此，doctrine为新表创建了一个新别名（php比较区分大小写github link）。

要解决此问题，请使用大写 P 将您的班级名称和文件更改为 CheckPoint ：

class CheckPoint
{
