How can I find out the specific role of an RBAC user?

Question

Yii

How can I find out the specific role of the RBAC user if the user has several roles. Preferably one request.

Answer 1

roles in yii2 are conditional, access is checked through the availability of actions user->can('manager') - manager conditionally this action with a flag that this action is a role.
With a properly implemented RBAC, for example, such a Yii::$app->user->can('manager') check in the code should work.
You can also filter actions in the controller by roles through accessRules()
