Rails - Oct 2006 - accessing :through table attributes

If I have the following (abridged) setup:

 

class User < ActiveRecord::Base

  has_many :groups, :through => :memberships

end

 

class Group < ActiveRecord::Base

  has_many :users, :through => :memberships

end

 

 

and my memberships table has:

 

user_id

group_id

joined_date

 

Let''s say I''ve got: @group.users.each do |user|  . end

 

How do I access their joined_date attribute?  It''s gotta be easy but I
can''t
seem to figure it out.  Do I need to write extra model code to pull out a
single membership record?

 

 

Thanks,

Chad

The membership model exists to serve as the meeting place for all the
info -- so go directly for the memberships:

   @group.memberships.each do |m|
     # do stuff with m.user and m.joined_date
   end

Ah... that''s perfect.  I was trying to pull a list of members and get
the membership info from that as opposed to pulling memberships and
getting member info.

Thanks!
