# Links between RBAC Module and Other Modules

This feature requires an enterprise license.

This document showcases the module links defined between the role-based access control (RBAC) Module and other Commerce Modules.

## Summary

The RBAC Module has the following links to other modules:

|First Data Model|Second Data Model|Type|Description|
|---|---|---|---|
|[User](https://docs.medusajs.com/resources/references/user/models/User) in [User Module](https://docs.medusajs.com/resources/commerce-modules/user)|`RbacRoleAssignment`|Read-only - has many|[Learn more](#user-module)|
|[Invite](https://docs.medusajs.com/resources/references/user/models/Invite) in [User Module](https://docs.medusajs.com/resources/commerce-modules/user)|`RbacRoleAssignment`|Read-only - has many|[Learn more](#user-module)|

***

## User Module

You assign roles to admin users to control their access. Medusa stores each of these grants as an `RbacRoleAssignment` record, as explained in the [RBAC Concepts](https://docs.medusajs.com/resources/enterprise/rbac/concepts#role-assignment) guide.

Since the assignment stores the granted entity's type and ID, it isn't a stored link between two data models. Instead, Medusa defines read-only links that expose the roles of a `User` or an `Invite` from the [User Module](https://docs.medusajs.com/resources/commerce-modules/user).

An admin user can have multiple roles, and a role can be assigned to multiple users. The user's effective policies are the union of the policies from all their unscoped role assignments. A [scoped assignment](https://docs.medusajs.com/resources/enterprise/rbac/concepts#scoped-assignments) only adds its role's policies to requests within that scope.

### Retrieve with Query

To retrieve the roles of an admin user with [Query](https://docs.medusajs.com/learn/fundamentals/query), pass `rbac_roles.*` in `fields`:

### query.graph

```ts
const { data: users } = await query.graph({
  entity: "user",
  fields: [
    "rbac_roles.*",
  ],
})

// users[0].rbac_roles
```

### useQueryGraphStep

```ts
import { useQueryGraphStep } from "@medusajs/medusa/core-flows"

// ...

const { data: users } = useQueryGraphStep({
  entity: "user",
  fields: [
    "rbac_roles.*",
  ],
})

// users[0].rbac_roles
```

The `rbac_roles` field returns the roles of all the user's assignments, including scoped ones, without their scope. To retrieve each assignment's scope, pass `user_role_assignments.*` in `fields` instead:

```ts
const { data: users } = await query.graph({
  entity: "user",
  fields: [
    "user_role_assignments.*",
    "user_role_assignments.role.*",
  ],
})

// users[0].user_role_assignments[0].scope
// users[0].user_role_assignments[0].scope_id
```

Pass the `rbac_roles.*` field when querying the `invite` entity to retrieve the roles that an invite grants once the user accepts it. Use `invite_role_assignments.*` to retrieve the invite's assignments with their scope.

To find the entities that a role is assigned to, query the `rbac_role_assignment` entity instead:

```ts
const { data: assignments } = await query.graph({
  entity: "rbac_role_assignment",
  fields: ["reference", "reference_id"],
  filters: {
    role_id: "role_123",
    reference: "user",
  },
})
```

### Manage Role Assignments

To assign a role to an admin user, use the `assignRolesWorkflow`:

```ts
import {
  assignRolesWorkflow,
} from "@medusajs/medusa/core-flows"

await assignRolesWorkflow(container).run({
  input: {
    assignments: [
      {
        role_id: "role_123",
        reference: "user",
        reference_id: "user_123",
      },
    ],
    granting_actor_id: "user_456",
  },
})
```

Pass a `scope` object with the `type` and `id` properties in an assignment to restrict the role to that scope.

To remove a role from an admin user, use the `unassignRolesWorkflow` with the same input shape:

```ts
import {
  unassignRolesWorkflow,
} from "@medusajs/medusa/core-flows"

await unassignRolesWorkflow(container).run({
  input: {
    assignments: [
      {
        role_id: "role_123",
        reference: "user",
        reference_id: "user_123",
      },
    ],
    granting_actor_id: "user_456",
  },
})
```

Both workflows check that the actor in `granting_actor_id` already has all the policies of the roles being changed. If the actor is acting within a scope, pass it in the `granting_scope` property, and pass the actor's type in `granting_actor` if it isn't `user`.

When you omit the `scope` of an assignment, the `unassignRolesWorkflow` removes all the matching assignments, both scoped and unscoped. It also fails if the removal leaves no admin user with the unscoped [Super Admin role](https://docs.medusajs.com/resources/enterprise/rbac/concepts#super-admin-role). The `deleteUsersWorkflow` runs the same check before deleting users.
