Question

Is there any one know what should I do so that users are required to fill in the input in request page only but not in create/update page? I had my own reason I want to do like that.

In User Model

array('user_email, user_name', 'required','on'=>'request'),  //I want this only occur when on my request page

In User Controller

public function actionRequest()
{
    $id=Yii::app()->user->uid;
    $model=$this->loadModel($id);

    if(isset($_POST['User']))
    {
        $model->attributes=$_POST['User'];
        if ($model->validate('request')) 
        {
            if($model->save())
            {
                $this->redirect(array('view','id'=>$uid));
            }
        }
    }

    $this->render('request',array(
        'model'=>$model,
    ));
}

But somehow this does not work.

You will have to create your model with the scenario so that the rules applicable to that scenario can be applied.

Let’s say your scenario is some_scenario, then when you declare the rules use like so:

array('user_email, user_name', 'required', 'on'=>'some_scenario')
// now the user_email, user_name will be required properties only when the scenario is 'some_scenario'

Now to apply a scenario to a model we have to create that model instance with that scenario, like so:

$model = new SomeModel('some_scenario');

Here’s a yii wiki that you might want to read.

Edit: In your case you can set the scenario after the model object is created, by directly setting the scenario property:

$model = $this->loadModel($id);
$model->scenario = 'request';
