Yii hasAttribute and Custom Fields

Question

How can I use hasAttribute with Custom Fields?

Code:

if ($model->hasAttribute($attribute)) {
    ...
} else {
    $this->_sendResponse(400, 'Parameter \''.$attribute.'\' is not supported.');
}

---

EXAMPLE

Model.php

class Model extends CActiveRecord
{

public $customField;
...

Code:

$model = new Model;
$model->hasAttribute('customField'); // Returns False.

You should simply use :

if (property_exists('Model', $attribute)) {

hasAttribute will only check for db attributes.
