I guess this is a problem due to out-of-order reference definitions.....
it's quite a leap to require web2py to know about auth_group when it's not
defined yet.......
Frankly, it should be treated as a bug (so, file an issue on google code)
only because of backwards compatibility
BTW,
auth_groups has a FK to auth_membership
auth_membership has a FK to auth_groups and a FK to auth_user
your model doesn't make any sense (and frankly, it's a waste of
functionality and doesn't improve any performance).... you're restricting a
user to be part of only one group, jumping from auth_user to auth_groups
without "passing" from auth_membership.
