What is the best way to organize a user model in Yii2?

Question

Yii

Hello. There are several types of users with specific fields in the database (some users require a separate table, and the general data is stored in the user table), specific methods and relationships with other tables. I would like to be able to write like this:

$reader = Reader::findOne($id);
$books = $reader->books;
//..
$librarian = Librarian::findOne($id);
$orders = $librarian->orders;
$librarian->clearCart();

+It is convenient to implement access through Yii::$app->user->identity
Question: what is the best way to organize models in this case?
Thank you.
