Djnago ORM 从两个表中选择

你好！我有两个模型通过 ForeignKey 相互连接

class User(models.Model):
    object = models.ForeignKey(Object, on_delete=models.CASCADE)

class Object(models.Model):
    count = FloatField()

告诉我如何为计数小于某个值的对象选择所有用户？我试过这样，但它返回一个空的查询集：

def get_queryset(self):
    ...
    return queryset.filter(object_id=object__location__distance_lt=10)
