[web2py] Is there any way to inherit from Row?

[Alfonso Serra]

I would like to subclass a Row object but cant get it right. What would be 
the way? 

from pydal.objects import Row

class Hotel(Row):
    _room_types = None
    _regimen_types = None
    _agencies = None
    _countries = None

    def __init__(self, db, id):
        super(Hotel, self).__init__()
        self = db.hotels[id]
    
    @property
    def agencies(self):
        self._agencies = self._agencies or db(db.hotels.id == self.id).
select(db.agencies.ALL, join=db.hotels.on(db.hotels.id == db.agencies.hotel
))
        return self._agencies

Thanks
