I cloned web2py and write 2 functions for that
http://code.google.com/r/pihentagy-web2py/source/list
You can use those classes like that:
Field('invoice_date','date',
requires=IS_DATE_IN_RANGE(minimum=datetime.date.today(),
format='%d/%m/%Y')),
Field('settlement_date','datetime',
requires=IS_DATETIME_IN_RANGE(minimum=datetime.datetime.now(),format='%H:%M:%S
%Y-%m-%d')),
I don't know why I do not see the newest version in googlecode (I am
not familiar with hg, but I think I managed to commit the changes).
Just in case here are they:
class IS_DATE_IN_RANGE(IS_DATE):
def __init__(self, minimum=None, maximum=None, **args):
self.minimum = minimum
self.maximum = maximum
self.error_message_low = args.pop('error_message_low', 'date
should be at least %(min)s')
self.error_message_high = args.pop('error_message_high', 'date
should be before %(max)s')
super(IS_DATE_IN_RANGE,self).__init__(**args)
def __call__(self, value):
(value, msg) = super(IS_DATE_IN_RANGE,self).__call__(value)
if msg is not None:
return (value, msg)
if self.minimum and self.minimum > value:
return (value, self.error_message_low %
{'min':self.minimum.strftime(self.format)})
if self.maximum and value >= self.maximum:
return (value, self.error_message_high %
{'max':self.maximum.strftime(self.format)})
return (value, None)
class IS_DATETIME_IN_RANGE(IS_DATETIME):
def __init__(self, minimum=None, maximum=None, **args):
self.minimum = minimum
self.maximum = maximum
self.error_message_low = args.pop('error_message_low',
'datetime should be at least %(min)s')
self.error_message_high = args.pop('error_message_high',
'datetime should be before %(max)s')
super(IS_DATETIME_IN_RANGE,self).__init__(**args)
def __call__(self, value):
(value, msg) = super(IS_DATETIME_IN_RANGE,self).__call__(value)
if msg is not None:
return (value, msg)
if self.minimum and self.minimum > value:
return (value, self.error_message_low %
{'min':self.minimum.strftime(self.format)})
if self.maximum and value >= self.maximum:
return (value, self.error_message_high %
{'max':self.maximum.strftime(self.format)})
return (value, None)
