Is it possible to give Yii2 RBAC permission to a user separately?

Question

Yii

Actually, you can give a separate Permissions without being tied to a role, the user can.
Is it correct?
And that this one is mixed will function normally when checking
Yii::$app->user->can('TEST')
Why I ask, since the getPermissionsByUser method from the \yii\rbac\DbManager class does not see permissions that are not tied to a role.

Answer 1

According to the RBAC ideology, only roles can be assigned to a user. Permissions can only be tied to roles. Accordingly, the user's permissions are checked only through roles.
That's what it says in the Yii doc.
