The initial way would be:

If you had a table clubs_people
  int club_id
  int person_id
  
class Club < ActiveRecord::Base
  has_and_belongs_to_many :people
end

class People < ActiveRecord::Base
  has_and_belongs_to_many :clubs
  # Rails would assume a table named clubs_people unless you specified otherwise
end


# A more sophisticated way would be to create a memberships table, which might have meta-attributes like date joined.
