How to delete data using join in yii2 - yii2

Question

I am using following query for delete all corresponding data to relate on given id My code:
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;
}
}
But here What i want Workorderpopup has a child table Workorderpopup_child i want delete all child record to but child table has no any relation with $pid Is there Any way to delete child's records too ?

Answer 1

Assuming that relation is workorderpopup_child.workorderpopup_id -> workorderpopup.id.
It could be something like this
Cascade delete by IN condition
$workorderpopups = Workorderpopup::find()
->select('id')
->where(['workorder_id' => $pid])
->asArray()->all();
Workorderpopup_child::deleteAll(['in', 'workorderpopup_id', array_values($workorderpopups)]);
Or like this:
Cascade delete by relation unlinking
$workorderpopups = Workorderpopup::find()
->select('id')
->where(['workorder_id' => $pid])
->asArray()->all();
foreach ($workorderpopups as $workorderpopup) {
$workorderpopup->delete();
}
and then override your Workorderpopup->delete() as follows
/**
* #inheritdoc
*/
public function delete()
{
$this->unlinkAll('workorderpopup_child', true);
return parent::delete();
}
and make sure you have corresponding relation workorderpopup_child in Workorderpopup class:
/**
* #return \yii\db\ActiveQuery
*/
public function getWorkorderpopup_child()
{
return $this->hasMany(Workorderpopup_child::className(), ['workorderpopup_id' => 'id']);
}
p.s. i haven't tested the code above, so here can be some mistakes
