Why doesn't authorization (authentication) work in Yii2?

Question

This

Tell me what could be the error, I'm trying to write authorization, but nothing comes out. the problem is that when trying to pass identity to \Yii::$app->user->login, for some reason the data is not saved in the session, and in cookies too.
Here is the action I'm processing:

function actionLogin () {
        $form_model = new trForm(); //создает модель

        if($form_model->load(\Yii::$app->request->post())){//лоудим модель получаем данные из формы. (емайл,пароль)

            $dataUser = $form_model::findIdentity($form_model->email); //ищем пользователя по email

            $validatePassword = $form_model->validatePassword($form_model->pass,$dataUser->hash); //получаем и сравниваем хеш и бд
            if($validatePassword && $dataUser){ //если все ок то аутефицируем пользвателя

                \Yii::$app->user->login($form_model,1000*60*60*24); //логиним
                echo '<pre>';
                var_export(\Yii::$app->session); //сессии пустые.
                // \Yii::$app->user->enableSession - true
                echo '</pre>';
                die;

               return $this->redirect('admin'); //редириктим в админку.
            }
        }
        return $this->render("login", compact('form_model'));//передает модель в вид login
    }

here is the model itself, which appears in this action:

I display separately $form_model - everything is displayed normally, but for some reason there is no logging (

Answer 1

trying to pass identity to \Yii::$app->user->login

the fact of the matter is that you are not passing identity , but the form model

$dataUser = $form_model::findIdentity($form_model->email); // тут identity
\Yii::$app->user->login($form_model,1000*60*60*24); //а вот что передаете

PS: By the way, I do not quite understand what is the point of referring to findIdentity as a static method. Since there is all the data in this object, then it would not be necessary to transfer email to it. In my opinion, the method should not be static.
