Question

Each application has instance. When I try propirat way to url mananager

'application/<slug:[\w+]+>/instance/create/' => 'instance/create',
'application/<slug:[\w+]+>/instance/<uuid:[\w0-9]+>/update/' => 'instance/update',

To open a link, set the path in the form of

$this->menu=array(
    array('label'=>'Create Instance', 'url'=>Yii::app()->createUrl('instance/create',  array('slug' => $model->application->slug, 'uuid' => $model->uuid))),
array('label'=>'Update Instance', 'url'=>Yii::app()->createUrl('instance/update', array('slug' => $model->application->slug, 'uuid' => $model->uuid))),

I get an error

include(optional_note.php): failed to open stream: No such file or directory 

What the file and that there has to be done to satisfy the referrals?

Update

public function actionCreate()                                         
{                                                                      
$model=new Instance;                                                  
    $model->application_id = $this->_application->id;                  

// Uncomment the following line if AJAX validation is needed          
// $this->performAjaxValidation($model);                              

if(isset($_POST['Instance']))                                         
{                                                                     
    $model->attributes=$_POST['Instance'];                               
    if($model->save())                                                   
            $this->redirect(array('view','uuid'=>$model->uuid));                
}                                                                     

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

Update

See:

CValidator::createValidator("optional_note", Instance, "uuid", array(0 => "length", "max" => 128)), 

Check rules for model

array('uuid', 'optional_note' ...

It’s wrong, need put column names in same string

array('uuid, optional_note', ...
