RBAC: cannot revoke assingment

[mogilka]

What steps will reproduce the problem?

1. Create an user 'jam' (successful)
2. Create a role 'marketer', no matter with or without permissions (successful)
3. Assign the user 'jam' with the role 'marketer' (successful)
4. Revoke the assignment 'jam-marketer' (fail)

   What is the expected result?

The assignment revoked, the user 'jam' has no role by name 'marketer'.

What do you get instead?

All Rbac functions works perfectly except the revoke.

AccessController revoke method:

`/* * Удаление роли пользователя * @param string $role имя роли * @param int $userid идентификатор пользователя * @throws NotFoundHttpException * @return \yii\web\Response / public function actionRevoke($role, $userid) { $auth = Yii::$app->authManager; $model = $auth->getAssignment($role, $userid); if (empty($model)) throw new NotFoundHttpException("There is no assignment \"$role\" for user \"$userid\".");

$res = $auth->revoke($role, $userid);
if (!$res)
    Yii::$app->session->setFlash('danger', Yii::t("yii", "Error"));
return $this->redirect(['assign', "userid"=>$userid]);
}`

• is the result of steps 1,2,3 visible in your DB?
• what do you see
• are you sure that the AuthManager is revoking from the right DB?

[alex-code]

revoke is expecting a yii\rbac\Role object not a string.

$role = $auth->getRole($roleName);
$res = $auth->revoke($role, $userid);

Thank you, sorry it's my fault
