auth.mygroups is a dictionary of (key,value) = (group_id,role)
This makes it easy to create objects like
db.define_table('thing',
Field('name'),
Field('groups_with_access','list:reference auth_group'))
and select them with
mythings =
db(db.thing.groups_with_access.contains(auth.mygroups.keys())).select(db.thing.ALL)
Before this makes it into stable I would like to hear comments and
suggestions for improvement.
