如何在django orm中使用> date？

from django.db import models

class Event(models.Model):
    title = models.CharField(max_length=200)
    date = models.DateField()
    description = models.TextField()

    def __str__(self):
        return self.title

# 查询所有事件并按发布日期排序
events = Event.objects.all().order_by('date')

events = Event.objects.all().order_by('date', '-')
