學說（Symfony3）可捕捉的致命錯誤：傳遞給（bundle）的參數1必須是（bundle）的一個實例，數組給出

Question

我在symfony或doctrine中遇到問題。 我有一個實體notificationsettinggroupdetail和notificationsettinggroup。

Notificationsettinggroup and notificationsettinggroup是主要細節，並在實體原則中具有連接條件。

的問題都交給我時，我想用刪除從主（notificationsetinggroup）數據細節：

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

，但是當我用這個，我得到了一些錯誤：

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 

這是代碼在控制器中：

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

哪裏是我的錯？

Answer 1

你傳遞一個數組不是實體，如果你不想要編輯的控制器試試這個：如果你想改變控制器試試這個（如果實施）

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

相反：

findOneNotificationGroupSettingDetailByMaster 

，而不是這樣的：

findNotificationGroupSettingDetailByMaster 

因爲findNotificationGroupSettingDetailByMaster回報的ARR唉不是一個單一的實體
