Role Based Access Control For Module

I added the source code for RBAC Module validation. We can check the access role in module level, controller level and action level.

add this in config/main.php

'authManager'=>array(
    'class'=>'CDbAuthManager',
    'itemTable'=>'authitem',
    'assignmentTable'=>'authassignment',
    'itemChildTable'=>'authitemchild',
    'connectionID'=>'db',  
),

AdminModule

class AdminModule extends CWebModule
{
    public function init()
    {
        // this method is called when the module is being created
        // you may place code here to customize the module or the application
        // import the module-level models and components
        $this->setImport(array(
            'siteadmin.models.*',
            'siteadmin.components.*',
        ));
    }
    
    public function beforeControllerAction($controller, $action)
    {
        if(parent::beforeControllerAction($controller, $action))
        {
            // this method is called before any module controller action is performed
            // you may place customized code here
            // echo "sdf".Yii::app()->user->checkAccess('admincontrolPost'); 
            if(Yii::app()->user->checkAccess('siteadmin'))
            { 
                return true;
            }
            else 
            {
                Yii::app()->request->redirect(Yii::app()->createAbsoluteUrl('site'));                               
            }
        }
        else
            return false;
    }
}
