If the user can only be a member of one group then use User belongs_to
group. If a particular member does not belong to a group then just
leave group_id nil. You will obviously have to allow for user.group
== nil in the code where appropriate. If he can belong to many (or
no) groups then use has_many :through as Dave suggested. You can test
user.groups to see if he is in any groups.
