Authorization (RBAC)

The bundle provides a four-level cascading permission system:

Resource-level → Team-level → Organization-level → Global system-level

Each level falls back to the next. A global super-admin passes every check without being explicitly named in each organization or resource.

Roles and permissions

Roles are identified by a unique code string. There is no scope column — the context is defined by the relation that uses the role:

Permissions are atomic capabilities attached to roles via the RolePermission pivot:

Role "org.admin" ──► Permission "org.invite"
                 ──► Permission "org.billing"
                 ──► Permission "org.settings"

Using voters in controllers

The bundle registers three voters automatically:

Global (no subject)

#[IsGranted('system.manage')]
public function adminDashboard(): Response { ... }

Checks: user → UserRole → Role → RolePermission → Permission.code.

Organization-scoped (subject = Organization)

#[IsGranted('org.invite', subject: 'organization')]
public function inviteMember(Organization $organization): Response { ... }

Checks: user → OrganizationMembership(org) → Role → Permissions. Falls back to global.

Resource-scoped (subject = ResourceAccessible entity)

#[IsGranted('write', subject: 'project')]
public function editProject(Project $project): Response { ... }

Checks: user → ResourceAccess(resource) → Role → Permissions. Falls back to team-level (if resource implements TeamAccessibleInterface), then org-level (if resource implements OrganizationOwnedInterface), then global.

Programmatic checks

use Derafu\PlatformBundle\Identity\Contract\Service\PermissionCheckerInterface;

class SomeService
{
    public function __construct(
        private readonly PermissionCheckerInterface $checker
    ) {}

    public function doSomething(UserInterface $user, Organization $org): void
    {
        // Global
        if ($this->checker->hasPermission($user, 'system.manage')) { ... }

        // Organization-scoped
        if ($this->checker->hasOrganizationPermission($user, $org, 'org.invite')) { ... }

        // Resource-scoped
        if ($this->checker->hasResourcePermission($user, $project, 'write')) { ... }
    }
}

How the cascade works

hasResourcePermission($user, $resource, 'write'):

1. If $resource implements ResourceAccessibleInterface: iterate the resource’s direct access entries for this user → check each role’s permissions for 'write'.
2. If not found and $resource implements TeamAccessibleInterface: iterate team access entries → for each team, check if the user is a member → if yes, check the team’s role permissions for 'write'.
3. If not found and $resource implements OrganizationOwnedInterface: call hasOrganizationPermission($user, $resource->getOrganization(), 'write').
4. If not found: call hasPermission($user, 'write') (global).

Any level returning true short-circuits the rest.

API Platform integration

The bundle’s voters work with API Platform’s security attribute out of the box — no extra configuration. API Platform calls Symfony’s AuthorizationCheckerInterface, which triggers the voters:

use ApiPlatform\Metadata\ApiResource;
use ApiPlatform\Metadata\Get;
use ApiPlatform\Metadata\GetCollection;
use ApiPlatform\Metadata\Post;

#[ApiResource(
    operations: [
        new GetCollection(security: "is_granted('ROLE_USER')"),
        new Get(security: "is_granted('read', object)"),
        new Post(security: "is_granted('write', object)"),
    ],
)]
class Project { ... }

The Get and Post operations pass object as the subject, so the ResourcePermissionVoter fires and resolves the full cascade (direct → teams → org → global). The GetCollection operation uses a global check (no subject), so the PermissionVoter fires.

For automatic listing filters (which rows the user sees), see Multi-tenancy & RLS.

Vote reasons (debugging)

All three voters add human-readable reasons to Symfony’s Vote object when they deny. Check the Web Profiler’s Security panel to see why a specific check failed:

User "[email protected]" does not hold permission "org.invite"
in organization #42.
