def namespace
  # XXX: We guess the namespace from the current controller's module name. This will work
  # most of the time but will break if the current record's controller exists in a different
  # namespace to the current controller, e.g. `BackEndAdmin::UsersController` and
  # `FrontEndAdmin::ThemesController` - if `FrontEndAdmin::ThemesController` renders a
  # collection of `User` objects, the "show" path will be wrong:
  # `front_end_admin_user_path`. Maybe descend through the full controller class tree to
  # find a best match ?
