Rails - Nov 2008 - making arrays of valid values user-editable--best practice?

Hey All,

I''ve got a couple of valid-value lists that I would keep as arrays in
the appropriate model.  So for instance:

  class Person < ActiveRecord::Base
    ROLE_NAMES = [''Admin Assistant'',
''Programmer'', ''Investigator'',
''Project Manager'', ''Other'']
    # blah blah blah
  end

Now I need to convert this into something the user can add values to.  The 2
options that come to mind are:
  - Make each such array a model in its own right.
  - Make a kind of meta-model that would hold all of these arrays, and use it to
populate all of these arrays at application startup.

I''m most attracted to the second option, but I''m not sure
it''s going to be much less work, since I''ll probably have to
fake out individual CRUD screens for each array, which seems like it could get
weird.

Anybody been down this road?

Thanks!

-Roy
