Is it possible to manually set the values ​​of the fields of the created model using yii\rest\CreateAction?

Question

Yii

Does yii\rest\CreateAction have a built-in way to prepare the created model? For example, so that I can manually set the ID of the author of the post being created (ID of the authorized user). You can of course use beforeAction() in ActiveRecord, or override actionCreate() in the controller, but maybe there is still a solution that works by analogy with findModel for view, update, delete and prepareDataProvider for index?
