Extending The Cwebuser

Bonjour,

Thanks to everyone for making my experience with Yii an enjoyable one.

Now check this out.

I was successfully able to add information to Yii::app()->user using this page.

http://www.yiiframework.com/wiki/60/add-information-to-yii-app-user-by-extending-cwebuser/

Now I have implemented mine in this manner

<?php

/**
 * UserIdentity represents the data needed to identity a user.
 * It contains the authentication method that checks if the provided
 * data can identity the user.
 */
class UserIdentity extends CUserIdentity
{
    private $_id;
 
    public function authenticate()
    {
        $username=strtolower($this->username);
        $user=User::model()->find('LOWER(username)=?',array($username));
        if($user===null)
            $this->errorCode=self::ERROR_USERNAME_INVALID;
        else if(!$user->validatePassword($this->password))
            $this->errorCode=self::ERROR_PASSWORD_INVALID;
        else
        {
            $this->_id=$user->id;
            $this->username=$user->username;
			$this->setState("user_rank",$user->user_rank);
            $this->errorCode=self::ERROR_NONE;
        }
        return $this->errorCode==self::ERROR_NONE;
    }
 
    public function getId()
    {
        return $this->_id;
    }
}

Unfortunately I get the error

" CException;Property "CWebUser.user_rank" is not defined" when the session /state is lost

How do I go around this problem to maybe at worst send the user to the login page or at best continue to save the state

Merci beaucoup
