学说（Symfony3）可捕捉的致命错误：传递给（bundle）的参数1必须是（bundle）的一个实例，数组给出

Question

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

Notificationsettinggroup and notificationsettinggroup是主要细节，并在实体原则中具有连接条件。

的问题都交给我时，我想用删除从主（notificationsetinggroup）数据细节：

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

，但是当我用这个，我得到了一些错误：

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 

这是代码在控制器中：

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

哪里是我的错？

Answer 1

你传递一个数组不是实体，如果你不想要编辑的控制器试试这个：如果你想改变控制器试试这个（如果实施）

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

相反：

findOneNotificationGroupSettingDetailByMaster 

，而不是这样的：

findNotificationGroupSettingDetailByMaster 

因为findNotificationGroupSettingDetailByMaster回报的ARR唉不是一个单一的实体
