Why is save() not working?

Question

Yii

Actually here is the code

$trailers=Trailers::findOne(['id_film'=>$film->id]);
           if(isset($trailers)) {
                        $trailers->description = $video;
                        $trailers->id_film = $film->id;
                        if($trailers->save()){}else{var_dump($trailers->getErrors());};
             }

in the debugger shows that it finds such a record but does not save it. Why?

Answer 1

Maybe beforeSave is overridden? it should return true.
