Python Django-在保存另一个模型期间保存一个模型

我需要在创建moden假期后在模型表中创建记录。我有一个员工创建了一个假期，假期期间的每个日期都必须转到model Tabel

    name = models.CharField('Name', max_length = 20) 
    last_name = models.CharField('Last name', max_length = 20) 

    def __str__(self):
        return self.last_name

class Vacation(models.Model):
    employee = models.ForeignKey(Employee, on_delete = models.SET_NULL, blank = True, null = True)
    vacation_type = models.ForeignKey(VacationType, on_delete = models.SET_NULL, blank = True, null = True)
    date_creation = models.DateTimeField(auto_now = True)
    start_date = models.DateField()
    end_date = models.DateField()
    duration = models.DurationField(default=timedelta)

class Tabel(models.Model):
    employee = models.ForeignKey(Employee, on_delete = models.SET_NULL, blank = True, null = True)
    date = models.DateField()
    day_type = models.ForeignKey(TabelType, on_delete = models.SET_NULL, blank = True, null = True)
    late_changes = models.BooleanField(default = False)

我从Django开始。假期创建后，我应该使用什么更新模型选项卡？

提前感谢您的建议

如评论中所述，您可以使用Django信号：

models.py或signals.py

from django.db.models.signals import post_save

@receiver(post_save, sender=Vacation)
def create_tabel(sender, instance, created, **kwargs):
    if created:
        Tabel.objects.create(employee=instance.employee)

另一个选项是覆盖

这回答了你的问题吗？

def save(self, *args, **kwargs):
    is_new = True if not self.id else False
    super(Book, self).save(*args, **kwargs)
    if is_new:
        Tabel.objects.create(employee=self.employee)
