Yii从Yii :: app-> user访问关系数据

I would like to know whether it is possible or if there is a easier way to do this.

On many pages i'd like to use the relational data, now every page i use it i place the following code:

<?php
    if(!Yii::app()->user->isGuest){
        $user = User::model()->findByPk(Yii::app()->user->id);
    }
?>

So I can use the following in the view:

$user->account->name

To display current users related account's name

It would be nice if I could just do the following:

Yii::app->user->account->name

Set state isn't what i'm looking for since it's not only the account name i want to use, and I don't want to add a state for all relational data I might want to use.

Solution

I combined the good of both answers to create the following:

class WebUser extends CWebUser {
private $_user;

public function getAccount(){
    if(!$this->isGuest && (!isset($this->_user) || Yii::app()->user->id != $this->_user->id)){
        $this->_user = User::model()->findByPk(Yii::app()->user->id);
    }
    if(!empty($this->_user)){
        return $this->_user->account;
    } else {
        return false;
    }

  }
}

So now I can use the following:

Yii::app()->user->account->name

The above method retrieves the data if the user is logged in and there is no data stored or the user has a different id.

Place it in Components and be sure to add the part Afnan talks about to the config (main.php)

I accept the answer of Afnan because it helped me most (The part I needed to know)

    Well i do not know if it is the best solution but i usually do things like this by extending CWebUser

    What i would do is create file in Components folder that extends CWebUser

    class CWebUserExtend extends CWebUser
    {
        /**
         *
         * @return the type of user based on forien key of UserType
         */
        public function getUserAccname()
        {
            $user = User::model()->findByPk(yii::app()->user->id);
            if ($user === null)
                return 'error';            
            else
                return $user->account->name;            
        }
    }
    

    and in main.php file modify 'User' index in following manner

    'user'=>array(
                // enable cookie-based authentication
                'allowAutoLogin'=>true,
                            'class'=>'CWebUserExtend',//class that extends CWebUser
            ),
    

    This would allow you to do something

    Yii::app()->user->getUserAccname();
    

    Hope it helps
