      The model class for `#{@controller_class}` could not be determined. Any controller that
      includes `RESTFramework::BaseModelControllerMixin` (directly or indirectly) must either set
      the `model` attribute on the controller, or the model must be deducible from the controller
      name (e.g., `UsersController` could resolve to the `User` model).
