[web2py] DAL orderby question: should this work?

[Cliff]

The book says to do orderby this way
        db.person.ALL, orderby=db.person.name

But I am using this:
    db.person.ALL, orderby='name'

Is this an undocumented feature that might go away at some point, or
can I continue to rely on it?

Thanks,
Cliff Kachinske
