What is the best way to filter data from user in Yii2?

Question

Yii

Sample code:

--------------------------- IN controller behavior -----------------------------
$post = Yii::$app->request->post();
foreach ($post as $key => $value){
  $post[$key] = удалитьЛишниеПробелыИДвойныеПустыеСтрокиВТекстовыхДанных($value);
}
Yii::$app->request->bodyParams = $post;
--------------------------- OR in model behavior------------------------------
foreach ($this->owner->attributes() as $attributeName => $attributeValue){
  $this->owner->{$attributeName} = удалитьЛишниеПробелыИДвойныеПустыеСтрокиВТекстовыхДанных($attributeValue);
}

In the controller through attaching behaviors to actions or in models through attaching behaviors during the beforeValidate event?

Answer 1

In general, the solution turned out to be this: make a filter-validator and hang it on the fields in the rules model. Then we will save ourselves from extra empty space both when receiving data from the user and from ourselves.

Answer 2

It's more logical to override the model's load method
