Hello All,

i am working on leave management for Odoo11. And i am stuck at one point where leave duration avail in quarantined(4 Parts) but my requirement related to value should be show for half day or full day leave. For eg. duration avail in (4, 4.25, 4.5,4.75,5) instead i needed(4, 4.5,5). So, anyone can help me? I found this is related with below odoo python code.

def _get_number_of_days(self, date_from, date_to, employee_id):
        """ Returns a float equals to the timedelta between two dates given as string."""
        from_dt = fields.Datetime.from_string(date_from)
        to_dt = fields.Datetime.from_string(date_to)
        if employee_id:
            employee = self.env['hr.employee'].browse(employee_id)
            return employee.get_work_days_count(from_dt, to_dt)
        time_delta = to_dt - from_dt
        return math.ceil(time_delta.days + float(time_delta.seconds) / 86400)

    @api.onchange('date_from')
    def _onchange_date_from(self):
        """ If there are no date set for date_to, automatically set one 8 hours later than
            the date_from. Also update the number_of_days.
        """
        date_from = self.date_from
        date_to = self.date_to
        # No date_to set so far: automatically compute one 8 hours later
        if date_from and not date_to:
            date_to_with_delta = fields.Datetime.from_string(date_from) + timedelta(hours=HOURS_PER_DAY)
            self.date_to = str(date_to_with_delta)
        # Compute and update the number of days
        if (date_to and date_from) and (date_from <= date_to):
            self.number_of_days_temp = self._get_number_of_days(date_from, date_to, self.employee_id.id)
        else:
            self.number_of_days_temp = 0

    @api.onchange('date_to')
    def _onchange_date_to(self):
        """ Update the number_of_days. """
        date_from = self.date_from
        date_to = self.date_to
        # Compute and update the number of days
        if (date_to and date_from) and (date_from <= date_to):
            self.number_of_days_temp = self._get_number_of_days(date_from, date_to, self.employee_id.id)
        else:
            self.number_of_days_temp = 0
