计算字段语法错误，修改如下： for record in self: year_diff = int(record.x_hr_month [0:4] ) - record.x_startdate_efficientcy.year month_diff = int(record.x_hr_month [4:] ) - record.x_startdate_efficientcy.month x_month = year_diff*12 + month_diff + 1 if record.x_employee_id.hire_date.day<15: if record.x_employeegrade == 'G1': record ['x_person_efficiency'] = 0 elif record.x_employeegrade == 'G5': record ['x_person_efficiency'] = 1 elif record.x_employeegrade == 'G2': if x_month<1: record ['x_person_efficiency'] = 0 elif 1<=x_month<=3: record ['x_person_efficiency'] = 0.25 elif 4<=x_month<=6: record ['x_person_efficiency'] = 0.5 elif x_month>=7: record ['x_person_efficiency'] = 1 elif record.x_employeegrade == 'G3': if x_month<1: record ['x_person_efficiency'] = 0 elif 1<=x_month<=3: record ['x_person_efficiency'] = 0.5 elif 4<=x_month: record ['x_person_efficiency'] = 1 elif record.x_employeegrade == 'G4': if x_month<1: record ['x_person_efficiency'] = 0 elif 1==x_month: record ['x_person_efficiency'] = 0.5 elif 2<=x_month: record ['x_person_efficiency'] = 1 else: if record.x_employeegrade == 'G1': record ['x_person_efficiency'] = 0 elif record.x_employeegrade == 'G5': record ['x_person_efficiency'] = 1 elif record.x_employeegrade == 'G2': if x_month<1: record ['x_person_efficiency'] = 0 elif 1<=x_month<=4: record ['x_person_efficiency'] = 0.25 elif 5<=x_month<=7: record ['x_person_efficiency'] = 0.5 elif x_month>=8: record ['x_person_efficiency'] = 1 elif record.x_employeegrade == 'G3': if x_month<1: record ['x_person_efficiency'] = 0 elif 1<=x_month<=4: record ['x_person_efficiency'] = 0.5 elif 4<=x_month: record ['x_person_efficiency'] = 1 elif record.x_employeegrade == 'G4': if x_month<1: record ['x_person_efficiency'] = 0 elif 1<=x_month<=2: record ['x_person_efficiency'] = 0.5 elif 3<=x_month: record ['x_person_efficiency'] = 1
