Yii redirecting the admin and authenticated user to the desired page - yii

Question

I am new to yii. I want my admin upon login from webapp/user/login to redirect to the page I want which is localhost/webapp/story right now it is redirecting me to the index.php.
I have also registered a user and given that user a role which is authenticated and I want that when my user(the authenticated user) logs in via webapp/user/login then that user is redirected to index.php.
so there are two things:
1. redirecting admin to the desired page which is webapp/story.
2. redirecting the authenticated user to index.php.
I am using yii user and right extension. Please help me with this.
The code LoginController is below:
<?php
class LoginController extends Controller
{
public $defaultAction = 'login';
/**
* Displays the login page
*/
public function actionLogin()
{
if (Yii::app()->user->isGuest) {
$model=new UserLogin;
// collect user input data
if(isset($_POST['UserLogin']))
{
$model->attributes=$_POST['UserLogin'];
// validate user input and redirect to previous page if valid
if($model->validate()) {
$this->lastViset();
if (Yii::app()->user->returnUrl=='/index.php')
$this->redirect(Yii::app()->controller->module->returnUrl);
else// yehen par kuch aye ga according
$this->redirect(Yii::app()->user->returnUrl);
}
}
// display the login form
$this->render('/user/login',array('model'=>$model));
} else
$this->redirect(Yii::app()->controller->module->returnUrl);
}
private function lastViset() {
$lastVisit = User::model()->notsafe()->findByPk(Yii::app()->user->id);
$lastVisit->lastvisit = time();
$lastVisit->save();
}
}

I think could be somethings like this
<?php
class LoginController extends Controller
{
public $defaultAction = 'login';
/**
* Displays the login page
*/
public function actionLogin()
{
if (Yii::app()->user->isGuest) {
$model=new UserLogin;
// collect user input data
if(isset($_POST['UserLogin']))
{
$model->attributes=$_POST['UserLogin'];
// validate user input and redirect to previous page if valid
if($model->validate()) {
$this->lastViset();
// Old code commentede
//if (Yii::app()->user->returnUrl=='/index.php')
// $this->redirect(Yii::app()->controller->module->returnUrl);
//else// yehen par kuch aye ga according
// $this->redirect(Yii::app()->user->returnUrl);
// new code
if (UserModule::isAdmin()){
$this->redirect(array('story/index'));
}
else {
$this->redirect(Yii::app()->user->returnUrl);
}
}
}
// display the login form
$this->render('/user/login',array('model'=>$model));
} else
$this->redirect(Yii::app()->controller->module->returnUrl);
}
private function lastViset() {
$lastVisit = User::model()->notsafe()->findByPk(Yii::app()->user->id);
$lastVisit->lastvisit = time();
$lastVisit->save();
}
}
