Yii2, how to correctly write getters for fields in a model?

Question

Yii

Tell me, please, how to do the following thing correctly, for example, we have a date after it, and it must be brought to a human-understandable form before output, how to do it right?

Answer 1

public function getCreated { return нужная_функция_форматирования($this->created_at); }
...
echo $model->created;

The only problem is that, despite the seeming convenience of model getters, formatting fields is, generally speaking, the task of the display layer.
