How not to refresh the page on login in a modal window in Yii?

Question

Yii

Hi all! Created an ajaxLink that loads the view (login form) into the modal window, when the data is correct, I immediately log in, but when the data is not correct, it takes me to the page with the view (it is rendered via renderPartial), how to make it so that errors were displayed in a modal window and I was not transferred to another page? Thank you.

// Контроллер Login
  public function actionLogin()
  {

    if (Yii::app()->user->isGuest) {
            if (isset($_POST['ajax']) && $_POST['ajax'] === 'UserLogin') {
            echo CActiveForm::validate($model);
            Yii::app()->end();
        }
      $model=new UserLogin;
      // collect user input data
      if(isset($_POST['UserLogin']))
      {
        $model->attributes=$_POST['UserLogin'];
        // validate user input and redirect to previous page if valid
        if($model->validate()) {
          $this->lastViset();
          if (Yii::app()->getBaseUrl()."/index.php" === Yii::app()->user->returnUrl)
            $this->redirect(Yii::app()->user->returnUrl);
          else
            $this->redirect('site/index');
        }
      }
      // display the login form
      $this->renderPartial('/user/login',array('model'=>$model));
    } else
      $this->redirect(Yii::app()->controller->module->returnUrl);
  }

<?php $this->endWidget(); ?>
