How to passing parameter to afterSave() Method in yii2? - yii2

Question

I'm new to yii2. I want to write afterSave() method after insert new record. My scenario is: when the user add a damage must be send email to him.
When user add damage, does not enter the serial number. I should read his name and serial damage but I don't know how to passing serial from Controller to model.
Damage Model:
public function getUser()
{
return $this->hasOne(User::className(), ['id' => 'user_id']);
}
public function afterSave($insert, $changedAttributes)
{
parent::afterSave($insert, $changedAttributes);
$name = $this->user->name;
$serial = ?
$to = $this->user->email;
$subject = 'new damage';
$body = 'mr'.$name.'your damage with serial number'.$serial.'is registered';
if ($insert) {
App::sendMail($to, $subject, $body);
}
}
DamageController:
public function actionAddDamage($serial){
$model = new Damage();
$gaurantee = Gaurantee::find()->where(['serial' => $serial])->andWhere(['user_id' => Yii::$app->user->id])->one();
if (!$gaurantee)
throw new ForbiddenHttpException('You don't access');
$model->gr_id = $gaurantee->id;
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
}
return $this->render('addDamage',
['model' => $model,
'servers' => $servers,
'gaurantee' => $gaurantee,
]);
}

Answer 1

public function init(){
$this->on(self::EVENT_AFTER_INSERT, [$this, 'sendMail']);
}
public function sendMail($event) {
}

Answer 2

First that comes to mind is to add attribute in damage model.
//Damage model
public $serial;
Then in your controller you can set value for this:
public function actionAddDamage($serial){
$model = new Damage();
$gaurantee = Gaurantee::find()->where(['serial' => $serial])->andWhere(['user_id' => Yii::$app->user->id])->one();
if (!$gaurantee)
throw new ForbiddenHttpException("you don't access");
$model->serial = $serial;
.....
In your afterSave() method you will have your serial as $this->serial.
2nd way is to get it from guaranty table since you have $this->gr_id , but this will generate 1 more db request.

You can create a property $serial in your Damage Model and assign the serial value to the $model->serial property in your Controller. For Example:
class Damage extends yii\db\ActiveRecord
{
public $serial = null;
public function afterSave($insert, $changeAttributes) {
// ...
var_dump($this->serial);
}
}
And in the controller you can assign $serial to the model:
public function actionAddDamage($serial) {
$model = new Damage();
$model->serial = $serial;
// ...
}
