Models: * Person * Club
Relationships * Membership * Committee
People should be able to join a club (Membership) People should be able to be on the board of a club (Committee)
For my application these involve vastly different features, so I would prefer not to use a flag to set (is_board_member) or similar.
I find myself wanting to write:
People has_many :clubs :through => :membership # :as => :member? :foreign_key => :member_id? has_many :clubs :through => :committee # as (above)
but I'm not really sure how to stitch this together
