when i tried to using prettydate it return [invalid date]
e.g.
*from gluon.tools import prettydate*
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
delta = request.now - row.created_on
* form.vars.duration = prettydate(delta,T)*
form.vars.price = row.room.category.price
form.vars.total_price = delta.days * row.room.category.price
else:
form.errors.check_in = 'enter a value'
any idea how to use prettydate output in sqlform.grid?
thank you very much
