Yii2 login from DB

I am trying to make a login from DB. As I understand it, for this I just need to replace the default User model. So I try this twice, but in both cases Yii::$app->user->isGuest

there is true

but should befalse

LoginForm.php

<?php

namespace app\models;

use Yii;
use yii\base\Model;


class LoginForm extends Model
{
    public $username;
    public $password;
    public $rememberMe = true;

    private $_user = false;


    /**
     * @return array the validation rules.
     */
    public function rules()
    {
        return [
            // username and password are both required
            [['username', 'password'], 'required'],
            // rememberMe must be a boolean value
            ['rememberMe', 'boolean'],
            // password is validated by validatePassword()
            ['password', 'validatePassword'],
        ];
    }


    public function validatePassword($attribute, $params)
    {
        if (!$this->hasErrors()) {
            $user = $this->getUser();

            if (!$user || !$user->validatePassword($this->password)) {
                $this->addError($attribute, 'Incorrect username or password.');
            }
        }
    }


    public function login()
    {
        if ($this->validate()) {

            return Yii::$app->user->login($this->getUser(), $this->rememberMe ? 3600*24*30 : 0);
        } else {
            return false;
        }
    }


    public function getUser()
    {
        if ($this->_user === false) {
            $this->_user = User::findByUsername($this->username); //default
        #    $this->_user = Users::findByUsername($this->username);//my try 1
        #    $this->_user = Users2::findByUsername($this->username); // my trey 2
        }

        return $this->_user;
    }
}
