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.

Those are some of the things I can think of that should help you build
your group show pages. Hope this gives you some ideas on how to proceed.
Thanks a million. Thats helps me a great deal. Sometimes you cant see

groups_controller.rb
def show
@group = Group.find(params[:id]);
…
…
end
With groups you can get memberships:
memberships = @group.memberships
From memberships you get users:
memberships.each do |membership|
membership.user
end
There are ways to get your ordering by taking advantage of named_scopes:

Also don’t forget about default_scope. That can be very useful for
providing default sort orderings to your models:
