How to implement a dynamic role in Symfony?

Question

symfony

I welcome colleagues.

I want to increase the versatility of the system being created.
Now I use roles ROLE_USER, ROLE_ADMIN, ...
I also use Voters.

But the problem lies in the fact that it ROLE_USER, ROLE_ADMINis tightly connected with the business logic.

Hence the problems, for example, the introduction of a new role requires additional changes in the code.
Further we go, worse it becomes.

What do I want to do.
I want to implement the ability to create a dynamic role.

That is, the administrator clicks to create a new role and configures it accordingly.

But here one unpleasant problem arises, in the interface I have to know that this particular role is an administrator or someone else in order to show and hide blocks depending on the role.

My Solution:
User
id = 1
name = 'Vasya'
role = 1

Role
id = 1
name = 'Administrator'
permissions = [''user.create, 'user.delete']

And in the controller

$this->denyAccessUnlessGranted(UserVoter::DELETE, $user);

And in I UserVoter
check if the given role allows deleting users.

In general, already advice.
Maybe someone has a better solution.

Zayuzal ACL but in this project it is redundant, and the roles in the classical implementation are not enough.
