Richard,
Thank you for your reply.
Using the code you suggested, implemented as this:
users=db().select(
db.auth_user.id, db.auth_user.first_name, db.auth_user.last_name, db.
auth_group.role,
left=[db.auth_membership.on(db.auth_user.id == db.auth_membership.
user_id),
db.auth_group.on(db.auth_membership.group_id==db.auth_group.id)])
returns all groups, including the user_%d groups. It's harder to read, so I
would like to see something like "None" where the user belongs only to a
user_%d group.
My other solution right now, rather than a report like this, is to check
group membership in the index() controller.
