hr_employee_base.py
hire_date = fields.Date(string="Hire Date", default=fields.Date.today)
calculate_start = fields.Date(string="Start Date", default=fields.Date.today, store=True, compute='_get_calculate_date', inverse='_write_calculate_date')

@api.onchange('hire_date')
def _get_calcuate_date(self):
    if self.hire_date > self.calculate_start:
      self.calculate_start = self.hire_date

def _write_calculate_date(self):
     if self.hire_date > self.calculate_start:
     self.calculate_start = self.hire_date

Hi,

try to re-write the two functions that you defined like below

@api.onchange('hire_date')
def _get_calcuate_date(self):
    for hr_employee_id in self:
        if hr_employee_id.hire_date > hr_employee_id.calculate_start:
            hr_employee_id.calculate_start = hr_employee_id.hire_date

def _write_calculate_date(self):
    for hr_employee_id in self:
        if hr_employee_id.hire_date > hr_employee_id.calculate_start:
            hr_employee_id.calculate_start = hr_employee_id.hire_date

Thank you very much,it works now.If you dont mind,one more question please,how to set the specific date like "2022-12-31" as default,not the default date as today?
