下面是我的代码

class Address(models.Model):
    line1 = models.CharField(max_length=150)
    line2 = models.CharField(max_length=150)
    postalcode = models.CharField(max_length=10)
    city = models.CharField(max_length=150)
    country = models.CharField(max_length=150)


class Anniversary(models.Model):
    date = models.DateField()

class Person(models.Model):
    name = models.CharField(max_length=50)
    birthday = models.DateField()
    anniversary = models.ForeignKey(Anniversary, on_delete=models.CASCADE)
    address = models.ForeignKey(
    Address, on_delete=models.CASCADE)

Answer 1

您可以将其添加到周年纪念模型中：

def __str__(self):
    return str(self.date)

这将在周年纪念下拉列表中显示日期
