基于属性值的Django模型继承?

Django model inheritance based on atribute value?

抱歉,我刚开始使用 Django 编程,需要帮助。

当父属性为真时,我需要一个 class(继承),因此在寻找子属性时 class,将所有拥有此属性的属性都设为真。

见代码:

class Person(models.Model):
    name = models.CharField(max_length=200)
    active = models.BooleanField(default=True)
    customer = models.BooleanField(default=False)
    employee = models.BooleanField(default=False)
    vendor = models.BooleanField(default=False)
    def __str__(self):
        return self.nome

class People(Person):
    registration_number = models.CharField(max_length=14)
    birth_date = models.DateField()
    sex = models.CharField(max_length=1)

class Company(Person):
    registration_number = models.CharField(max_length=20)
    foundation_date = models.DateField(blank=True, null=True)
    class Meta:
        ordering = ["nome"]

class Customer(Person):
    # I want to consider all Person object with customer=True

您只需像这样过滤您的个人查询:

customers = Person.objects.filter(customer=True)

你不需要另一个 class
