people_controller.rb:
class PeopleController < ApplicationController
end

the PeopleController shall handle all people (asia, europe, america, africa, australia):

but i'd like to have routes like:
- /asia/12 -> PeopleController.show params=>{:id=>12, :continent=>'asia'} :get
- /america  -> PeopleController.index params=>{:continent=>'america'} :get
- /africa/3/edit -> PeopleController.edit params=>{:id=>3, :continent=>'africa'} :get

map.people '/:person', :controller=>:people,

i expected: people_path(:person=>'asian') to create /asian but it creates /people?person=asian
