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?
