How can I use Yii2-images to load an image when a post is published?

Question

Yii

Good afternoon,
in this plugin $model = Posts::findOne($id); takes the value of the id of the record in the database to which the association with the record of the uploaded image will be assigned. Is there any option to attach to a post that doesn't exist yet?
The option to write +1 to the id of the last entry is not suitable, it gives an error, because this entry does not exist.

Answer 1

In the afterSave() method;
