Yii2 remove unique validator - yii2

Question

I have an AR model, it has the following rules:
/**
* #inheritdoc
*/
public function rules() {
return [
[['category_id', 'source', 'url', 'title', 'thumbs', 'duration', 'status', 'created_at'], 'required'],
[['category_id', 'status', 'views', 'ratings', 'created_at'], 'integer'],
[['rating'], 'double'],
[['source', 'url', 'title', 'slug'], 'string', 'max' => 255],
[['url'], 'unique', 'on' => 'create'],
[['category_id'], 'exist', 'skipOnError' => true, 'targetClass' => Category::className(), 'targetAttribute' => ['category_id' => 'id']],
];
}
I want to do a soft delete so I have the following.
/**
* Deletes an existing Video model.
* If deletion is successful, the browser will be redirected to the 'index' page.
* #param integer $id
* #return mixed
*/
public function actionDelete($id)
{
$model = $this->findModel($id);
$model->status = 0;
//var_dump($model->validate());
//var_dump($model->getErrors());die;
$model->save();
return $this->redirect(['index']);
}
But unfortunately I cannot change the status of model, because the validation says that (The url xxxxxxx has been taken) so I went to the PostgreSql, and I checked the records, but unfortunately only the updating record has this value! So in my mind the Yii2 unique validatios is bad. I would like to remove the unique validator, but it seems it is impossible. Because I commented out the uniqure row in the rule array, but it did not help me. I restarted the machine, but I do not know, it seems Yii2 want always check the url is unique or not.

Answer 1

You can use scenario
public function scenarios()
{
$scenarios = parent::scenarios();
$scenarios['soft_delete'] = ['status',]; //Scenario Values Only Accepted
return $scenarios;
}
public function actionDelete($id)
{
$model = $this->findModel($id);
$model->status = 0;
$model->scenario = 'soft_delete';
//var_dump($model->validate());
//var_dump($model->getErrors());die;
$model->save();
return $this->redirect(['index']);
}
or another way is suppress validation for this action
public function actionDelete($id)
{
$model = $this->findModel($id);
$model->status = 0;
//var_dump($model->validate());
//var_dump($model->getErrors());die;
$model->save(false);
return $this->redirect(['index']);
}
