python - Django 模型中的默认过滤器

Question

是否可以在 Django 模型中设置默认过滤器？

类似于:

class MyModel(models.Model):
    timestamp = models.DateTimeField(default=datetime.utcnow)
    active = models.BooleanField(default=True)

    class Meta:
        ordering = ['-timestamp']
        filtering = [active=True]

Answer 1

您必须覆盖 manager :

class MyModelManager(models.Manager):
    def get_queryset(self):
        return super(MyModelManager, self).get_queryset().filter(active=True)

class MyModel(models.Model):
    timestamp = models.DateTimeField(default=datetime.utcnow)
    active = models.BooleanField(default=True)

    objects = MyModelManager()

    class Meta:
        ordering = ['-timestamp']

get_queryset 在 Django 1.6 之前是 get_query_set
