How do you implement user roles and permissions in FuelPHP?

Answer: In FuelPHP, you can implement user roles and permissions by following these steps:

1. Database Design: Create tables for `users`, `roles`, and a pivot table (e.g., `role_user`) for many-to-many relationships between users and roles. You may also need a `permissions` table if you want granular control.

2. Model Setup: Create models for `User`, `Role`, and `Permission`. Define relationships between these models (e.g., a User has many Roles).

3. Authentication and Authorization: Use FuelPHP’s built-in Auth package. Configure it with the necessary providers (e.g., database provider for users) and add methods to check roles and permissions.

4. Middleware or Filters: Implement filters or middleware to check user roles/permissions before accessing certain routes or actions within controllers.

5. Role Management: Create admin interfaces for adding/removing roles and assigning them to users, handling updates to permissions as necessary.

6. Usage in Application: Use helper methods (e.g., `Auth::has_role()`, `Auth::has_permission()`) in controllers to conditionally display content or enforce access controls based on user roles.

This structure provides a robust way to manage user roles and permissions in your FuelPHP application.
