map.resources, restricting to only /index and /show

Is there a way to restrict the routes that get generated by map.resources to only /index and /show? On the frontend have no need for edit and delete.

That's done automatically. Just don't implement edit and destroy
actions on the corresponding controller. People will get a 406 Not
