How to properly link models on view?

Question

Yii

Good afternoon. Can you tell me how to properly link models in yii2?
There is a simple model that has another model attached to it.
Store - id, name , id_city
City - id, name
What is the correct way to get this link, call it in the controller?
type

Магазин::find()->joinWith('Город')->where('ид'=>$id)->one();

or use afterFind() ?
If afterFind, please tell me how to do it right?
