Question

我正在使用以下查询删除所有相关数据，以便在给定的ID我的代码：

上进行关联

  public function actionDeletebyajax() 

  {
  $pid = $_POST['id'];   
  if($pid) {
        $this->findModel($pid)->delete();
        Profile::deleteAll('user_id ='.$pid);
        UserLoyalty::deleteAll('store_id ='.$pid);
        Workorderpopup::deleteAll('workorder_id ='.$pid); 
        Deal::deleteAll('workorder_id ='.$pid); 
        WorkorderCategory::deleteAll('workorder_id ='.$pid);
        store::deleteAll('owner ='.$pid);
        workorders::deleteAll('workorder_id ='.$pid); 
       echo $pid; exit;
 }
 }

但是这里我想要的Workorderpopup有一个子表Workorderpopup_child我想要删除所有子记录但是子表与$pid没有任何关系有没有办法删除子记录呢？

假设关系是workorderpopup_child.workorderpopup_id - ＆gt; workorderpopup.id。

可能是这样的

按条件删除级联

$workorderpopups = Workorderpopup::find()
    ->select('id')
    ->where(['workorder_id' => $pid])
    ->asArray()->all();

Workorderpopup_child::deleteAll(['in', 'workorderpopup_id', array_values($workorderpopups)]);

或者像这样：

按关系取消链接级联删除

$workorderpopups = Workorderpopup::find()
    ->select('id')
    ->where(['workorder_id' => $pid])
    ->asArray()->all();

foreach ($workorderpopups as $workorderpopup) {
    $workorderpopup->delete();
}

然后按以下方式覆盖您的Workorderpopup->delete()

/**
 * @inheritdoc
 */
public function delete()
{
    $this->unlinkAll('workorderpopup_child', true);        

    return parent::delete();
}

并确保您在workorderpopup_child课程中有相应的关系Workorderpopup：

/**
 * @return \yii\db\ActiveQuery
 */
public function getWorkorderpopup_child()
{
    return $this->hasMany(Workorderpopup_child::className(), ['workorderpopup_id' => 'id']);
}

P.S。我没有测试上面的代码，所以这里可能会出现一些错误
