How does the code below (p. 268) work? Is it definitely correct? Can someone walk me through this? In actionSetup (A): Why is updateUser a child of updateOwnUser? Doesn't that mean anyone who can update his/her OWN user info can also update anyone else's? In the controller (: Why is checkAccess (array('id' => $id)) used on updateUser instead of updateOwnUser? Does updateUser even use the ID parameter? Please help - thanks... Quite confused! Code A: # protected/controllers/SiteController.php::actionSetup() $auth = Yii::app()->authManager; // Create operations. $task = $auth->createTask('updateOwnUser', 'Allows a user to update her record', 'return $params["id"] == Yii::app()->user->id;'); $task->addChild('updateUser'); Code B: # protected/controllers/UserController.php public actionUpdate($id) { $model=$this->loadModel($id); if (!Yii::app()->user->checkAccess('updateUser', array('id' => $id))) { throw new CHttpException(403, 'You are not allowed to do this.'); } // Code for doing this. }

I've been following this tutorial, which is great btw, and have one question. http://www.larryullman.com/2010/01/07/custom-authentication-using-the-yii-framework/ I can access the role property like this, anywhere in my application code: Yii::app()->user->role but, what I'd really like to do is use the default controller authorization in my UserController: /** * Specifies the access control rules. * This method is used by the 'accessControl' filter. * @return array access control rules */ public function accessRules() { return array( array('allow', // allow all users to perform 'index' and 'view' actions 'actions'=>array('*'), 'users'=>array('@'), // Fails 'roles'=>array(ModelConstantsRole::ADMIN), // Also Fails 'expression'=>'(isset(Yii::app()->user->role) && (Yii::app()->user->role==ModelConstantsRole::ADMIN))', ), array('deny', // deny all users 'users'=>array('*'), ), ); } It appears that the class that actually validates the rules defined in accessRules doesn't actually know anything about my role that I've assigned it. CAccessControlFilter (for those of you who don't want to search for it for 40 minutes XD). Any ideas on how I can make use of the accessRules method when I combine it with Larry's approach? Thanks!
