[web2py] CRON or Background script?

[Ismael Serratos]

hi! I need to run this


import time
def bookings():

    import datetime

    allBookings = db(db.current_bookings).select()
    db.commit()

    for booking in allBookings:
        if booking.enddate >= datetime.datetime.now():
            buildingName = booking.project
            room= booking.platform

            table = getattr(db, '%s'%buildingName )

            toUpdate = db(table.id == room).select()
            db.commit()

            for t in toUpdate:
                t.update_record(room_owner = 'Free')
                db.commit()

            booking.delete()

            db.commit()

        else:
            pass


while True:
     bookings()
     time.sleep(1)





as a background service, I tried with cron (nothing happened) could you tell
me if is something wrong with my script?? or how should I run it?? as a
command line script?? or via cron??
