在django中同时对两个字段进行计算，但一次只执行一个

Question

我正在尝试同时执行这两个操作，但一次只返回一个。如果我删除其中任何一个，另一个会被执行。有没有办法让他们两个同时工作？我说的是 Grossannualsalary 和 textDeduct。

class Salarie(models.Model):

    grossmonthlysalary = models.FloatField(
        _('Monthly Salary'),
        null=False,
        blank=False,
        default=0.00
    )

    monthlyincometax = models.FloatField(
        _('Monthly Income Tax'),
        null=False,
        blank=False
    )

    contractperiod = models.IntegerField(
        _('Contract Period'),
        null=False,
        blank=False
    )

    grossannualsalary = models.FloatField(
        _('Gross Annual Salary'),
        null=True,
        blank=True
    )

    taxDeduct = models.FloatField(
        _('Tax Deduction'),
        null=False,
        blank=False,
        default=0.00
    )

    def save(self, *args, **kwargs):
        self.grossannualsalary = self.grossmonthlysalary * self.contractperiod
        super(Salarie, self).save(*args, **kwargs)

    def save(self, *args, **kwargs):
        self.taxDeduct = self.grossmonthlysalary * self.monthlyincometax / 100
        super(Salarie, self).save(*args, **kwargs)

Answer 1

我不明白你为什么在一个模型中编写两个保存方法。请试试这个。

def save(self, *args, **kwargs):
    self.grossannualsalary = self.grossmonthlysalary * self.contractperiod
    self.taxDeduct = self.grossmonthlysalary * self.monthlyincometax / 100
    super(Salarie, self).save(*args, **kwargs)
