Question

How to correctly create a rule so that the post can be edited by a user with the admin role and the author of the post (post.user_id == user.id), if editing is allowed (allowEdit == true)? And how to use it then?

1. In code:

if (Yii::$app->user->can('admin') || $post->user_id == Yii::$app->user->id) {
   // ...
}
