How to use bizrule in yii rbac?

Question

Yii

Rbac is configured according to this recipe
yiiframework.ru/doc/cookbook/en/access.rbac.file
how to use bizrule in auth.php config file and in view?
Let's say a file can only be downloaded by a certain person.
In the view, of course, you can write
if(Yii::app()->user->id == $file->user_id)
But then the administrator will not be able to download this file if he logs in under his account.

Answer 1

$role = Yii::app()->authManager->getRoles(Yii::app()->user->id);
check if this is an admin or not, but in general you can write in the rules who has access to the action
