[Augustus Costa]

I´m looking for a way to work with compose primary keys.
I alredy know that plugin http://compositekeys.rubyforge.org/
but it doesn´t have examples.

Please help =]

What do you mean it doesn't have examples? What is this:

class Membership < ActiveRecord::Base
# set_primary_keys *keys - turns on composite key functionality
set_primary_keys :user_id, :group_id
belongs_to :user
belongs_to :group
has_many :statuses, :class_name => 'MembershipStatus', :foreign_key =>
[:user_id, :group_id]
end

there's a Google group "Composite Keys for ActiveRecord" that you
might look at for tips
