> > @group.group_users.group_admin =1 (X- NOT WORKING THOUGH)@group.group_users is not a single entity with the group_admin attribute, it''s a collection of group_users records... @group.group_users.each do |group_user| group_user.group_admin = 1 end would set that attribute for every group_user record, but I don''t think that is you want to do. I''d think you want to assign the group_admin for a single group_users record for the group, which you''ll need to select according to the user_id. A particularly ugly, but very clear implementation, might be: @group.group_users.each do |group_user| if group_user.user_id == the_user_id_of_your_admin group_user.group_admin = 1 end end -- Posted via http://www.ruby-forum.com/.
