brilliant, very simple solution, it's work now.
thank you so much for your solution and suggestion, massimo
i've followed your hints and make it on my controller :
def __onvalidation_check_out(form):
if form.vars.check_in:
rows = db(db.check_in.id==form.vars.check_in).select()
for row in rows:
form.vars.room = row.room
form.vars.guest = row.guest
form.vars.price = row.room.category.price
delta = request.now - row.created_on
form.vars.duration = delta
form.vars.total_price = delta.days * row.room.category.price
else:
form.errors.check_in = 'enter a value'
another question is it possible to make time delta more human readable?
for example on my code above the time delta return :
9 days, 0:00:34.024219
is it possible to make it?
9 days, 0:00:34.024219 = 9 days, 34 seconds
9 days, 0:01:34.024219 = 9 days 1 minute 34 seconds
9 days, 0:02:34.024219 = 9 days 2 minutes 34 seconds
9 days, 1:01:34.024219 = 9 days 1 hour 1 minute 34 seconds
9 days, 2:01:34.024219 = 9 days 2 hours 1 minute 34 seconds
thanks and best regards
