python - Django 查询链接多个过滤器

Question

这是我的日程对象，

class Schedule(Base):
    tournament = models.ForeignKey(Tournament, on_delete=models.CASCADE, null=True)
    first_team = models.ForeignKey(Team, related_name="first_team", on_delete=models.CASCADE, null=True)
    second_team = models.ForeignKey(Team, related_name="second_team", on_delete=models.CASCADE, null=True)
    first_score = models.IntegerField(default=0, null=True)
    second_score = models.IntegerField(default=0, null=True)
    sport = models.ForeignKey(Sport, on_delete=models.CASCADE, null=True)
    date = models.DateTimeField()

I want to fetch the schedules for a specific sport, for the past 30 days for tournaments which have anything other than a 0.0 bias.

这是我的查询

schedules = Schedule.objects.filter(sport=sport).filter(date__gte=date.today()).filter(
                        date__lte=(date.today() + timedelta(days=30))).order_by("date").exclude(tournament__bias=0.0)

这行不通，有人可以帮我吗？谢谢。

Answer 1

您的代码是正确的过滤方式(尽管您可以通过逗号分隔查找合并两个 filter() 方法)。

问题可能是您现在正在过滤:

today() <= date <= today() + 30 days 

因此，如果您没有任何实例的日期在未来 30 天(或今天)内，您将得到一个空集。
