I am writing an application where users can become members of different groups. On each group page I want to list all the members of the group by user name and also the groups to which they belong. My group table consistes of id, name, description. My membership table consists of id, user_id, group_id, role. How would I define the members and groups in my controller to do this and also how could I list them in my views? Thanks in advance, Steve. -- Posted via http://www.ruby-forum.com/.

Hope this gives you some ideas on how to proceed. -- Posted via http://www.ruby-forum.com/.

That can be very useful for providing default sort orderings to your models: http://www.railsbrain.com/api/rails-2.3.2/doc/index.html?a=M002363&name=default_scope -- Posted via http://www.ruby-forum.com/.
