根据时间间隔聚合字段

Question

我有一个这样的模型：

class MyModel(Model):
    pub_date = DateTimeField(auto_now_add=True)
    hours = IntergerField()

    def get_weekly_hours(self)
        # Find a week-ago interval based on the pub_date
        # Then based on the interval found above, aggregate the...
        # Sum the `hours` altogether
        pass

如何获取时间间隔，然后根据该值求和？
