Why not work RBAC in Yii2?

Why not work RBAC in Yii2?

Hi!
Actually the question. Create role create permission, attach a permission to the role. Add the role to the user.
But why is a user with this role the access is not receiving.

As:

$auth = \Yii::$app->authManager;

 $admin = $auth->createRole('admin');
$auth->add($admin);

 $showFilter = $auth->createPermission('showFilter');
 $showFilter->description = "Show filter";
$auth->add($showFilter);

 $auth->addChild($admin, $showFilter);

 $auth->assign($admin, 76);

But calling
Yii::$app->user->can('showFilter')
why it returns false. Help to understand why. Did everything according to the documentation. As there is Authorization

UPDATE:
If you write
Yii::$app->user->can('admin')
the access is, not running it through the "permission" attached to the role. Even if the role of the role of cabling, access via the child role he gets (

Yii::$app->user->getId() == 76?

Yes, the same. Upon receipt of the roles for a user, he gets the role 'admin' - Cindy.Oberbrunner32 commented on July 9th 19 at 14:02

Solution

Maybe you have cache enabled for RBAC, look for the line "'authManager' => [" in the project, if looks like this:

'authManager' => [
 'class' => 'yii\rbac\DbManager',
 'cache' => 'cache'
],

This means the cache RBAC is enabled, remove the virgin 'cache' => 'cache' , and will be the norm or invaliditatea cache:
Yii::$app->authManager->invalidateCache();

Thank you very much. You solved my problem... Cleaned the cache, worked. But after the Yii::$app->authManager->invalidateCache(); does not work if cache is not removed. - Cindy.Oberbrunner32 commented on July 9th 19 at 14:00

There is often a problem with the rights, it all comes down to what is necessary to remove the folder from rb runtime/cache - burnice commented on July 9th 19 at 14:03
