Rails - May 2008 - Need some assistance with routing -- 'resource' using natural key

I want to create a resource, let''s say ''cars'', which
are accessed by
license_number rather than id.
The column in question is guaranteed to be unique and unchanging (and
no, it''s not actually a car table).

Best way to go about this?


Thank you,
Isak

class Cars < ActiveRecord::Base
  ...
  def to_param
    return self.license_number
  end
  ...
