import worked to elimitate error but requires logic doesn't take
db.auth_group.role.requires not(IS_INT_IN_RANGE(-sys.maxint -1, sys.maxint))
not sure how to structure the syntax in the try: statement.
x=role(IS_INT_IN_RANGE(-sys.maxint
-1, sys.maxint) ?
how about a requires clause that is some kind of lambda that requires any
non-numeric? Is that possible? db.auth_group.role.requires=role contains
('a', 'b', 'c', etc)
I prefer a requires to a try: as it catches the error earlier and obviates
housekeeping
