Roles UI is a graphic interface library for Ruby on Rails which provides the ability to manage roles and permissions in realtime for applications which use Cancan. It is a Rails engine, so it has its own namespace. You can reach Roles UI in /roles_ui. Roles UI consist of two main entities, Role and Permission. Each Role may have a permission set. Roles belongs to users. Roles UI extends your User model so you don't need to create this association. By default, Roles UI is configured to work with the User model.
