Yesterday, a fellow developer was suprised we didn't have .one in web2py.
The idea is like this...
http://docs.sqlalchemy.org/en/latest/orm/query.html#sqlalchemy.orm.query.Query.one
be sure to also look at one or none.
Should we add this to the DAL?  I think it may come in handy.  Or should we
always just check the length.
I wonder what else SQLalchemy has the DAL could use.
BR,
Jason Brower
