I would to do :
def read():
id = request.args(0,cast=int,default=None)
if id is None:
location = db(db.location.id == request.args(0)).select().first()
else:
default_sort_order = [db.location[x] for x in 'city street_name
street_number building name'.split()]
locations = db().select(orderby = default_sort_order)
return locals()
