Question

我想按降序对模型对象进行排序，我应该如何使用模型类中的字段 number 进行排序。

这是我的views.py：

class SeasonDetailView(DetailView):
  
    model = CartoonSeason
    template_name = "episode_list.html"

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context["episodes"] = Episode.objects.filter(season=self.object)
        return context



class EpisodeDetailView(DetailView):
  
    model = Episode
    template_name = "episode.html"

这是我的models.py：

class Episode(models.Model):
    season = models.ForeignKey(CartoonSeason, on_delete=models.CASCADE)
    number = models.IntegerField()
    cover  = models.URLField(max_length=300, blank=True, null=True)
    name = models.CharField(max_length=200, blank=True, null=True)
    description = models.TextField(blank=True, null=False)
    link = models.URLField(max_length=300, blank=True, null=True)
    published = models.DateField(auto_now_add=True, blank=True, null=True)

class Episode(models.Model):
    season = models.ForeignKey(CartoonSeason,on_delete=models.CASCADE)
    number = models.IntegerField()
    cover  = models.URLField(max_length=300, blank=True, null=True)
    name = models.CharField(max_length=200, blank=True, null=True)
    description = models.TextField(blank=True, null=False)
    link = models.URLField(max_length=300, blank=True, null=True)
    published = models.DateField(auto_now_add=True, 
    blank=True,null=True)


    class Meta:
        verbose_name = _("Episode")
        verbose_name_plural = _("Episodes")
        ordering = ["season"]

在这种情况下如何修复 django 中的 UnicodeDecode 错误？
