When I traying to subtract this :

def get_duration(self):
    for rec in self:
        if rec.notification:
            if rec.notification == 'month':
                rec.notification_date = self.date_end - fields.Date(date.today() + relativedelta(months=1))
                print(type(self.date_end))
                print(type(date.today() + relativedelta(months=1)))

I get this error unsupported operand type(s) for 'datetime.date' and 'Date'.

Hi jenan soliman,

You are trying to subtract between different data types. you can use following code for finding today's date. So both the datatypes will be in same format (fields.Date()). When you subtract two date objects, you will get the difference of those dates only. it will be a datetime.timedelta() object not a date object . So you have to find the date again using this timedelta object . See the code snippet below.


date_today = fields.Date.today()
date_difference = self.date_end - (date_today + relativedelta(months=1))
rec.notification_date = self.date_end - relativedelta(days=date_difference)

Thanks

Happy to help,

hi Muhsin,
I tried this, but I also get this error
'datetime.timedelta' object is not subscriptable.
