Question

我在symfony或doctrine中遇到了问题。我有一个实体notificationsettinggroupdetail和notificationsettinggroup。

Notificationsettinggroup和notificationsettinggroup是主要详细信息，并且在实体原则中具有连接条件。

当我想使用以下方法从主文件（notificationsetinggroup）中删除数据详细信息时，问题就出现了：

    /**
 * Remove notificationSettingGroupDetail
 *
 * @param \Dsp\DspAdministrationBundle\Entity\notificationSettingGroupDetail $notificationSettingGroupDetail
 */
public function removeNotificationSettingGroupDetail(notificationSettingGroupDetail $notificationSettingGroupDetail)
{
    $this->NotificationSettingGroupDetail->removeElement($notificationSettingGroupDetail);
}

但是当我使用它时，我收到了一些错误：

Catchable Fatal Error: Argument 1 passed to Dsp\DspAdministrationBundle\Entity\notificationSettingGroup::removeNotificationSettingGroupDetail() must be an instance of Dsp\DspAdministrationBundle\Entity\notificationSettingGroupDetail, array given, called in C:\xampp\htdocs\Symfony-DspWebApp\src\Dsp\DspAdministrationBundle\Controller\Api\ApiNotificationSettingGroupController.php on line 122 and defined

这是控制器中的代码：

$entityDetailDelete = $this->getDoctrine()->getRepository(notificationSettingGroupDetail::class)->findNotificationGroupSettingDetailByMaster($userOld[$i]['id']);
$entity->removeNotificationSettingGroupDetail($entityDetailDelete);

我的错在哪里？

您传递的数组不是实体，如果您不想编辑控制器，请尝试以下操作：

public function removeNotificationSettingGroupDetail(array $notificationSettingGroupDetails)
{
    foreach (notificationSettingGroupDetails as notificationSettingGroupDetail) {
        $this->NotificationSettingGroupDetail->removeElement($notificationSettingGroupDetail);
    }
}

相反，如果您想更改控制器，请尝试此操作（如果已实施）：

findOneNotificationGroupSettingDetailByMaster

而不是：

findNotificationGroupSettingDetailByMaster

因为findNotificationGroupSettingDetailByMaster返回的数组不是单个实体

Doctrine（Symfony3）Catchable Fatal Error：传递给（bundle）的参数1必须是（bundle）的一个实例，给出的数组
