Answer 1

hi , how to translate this code to beforesave ?

copy and paste, replace $modelwith $this
But only afterSave, because in beforeSave new models do not yet have id

Answer 2

1) check at least validate() when loading into the model. Otherwise, it may be that the model does not pass validation, and you redirect and the person loses everything that he entered.
2) You need $model->id to work. You can get it in the afterSave() function;
