Django，UpdateView删除表中的一行

我完成了一个脚本的重新制作，因为我认为，另一个组件正在删除数据库中的一行，但它没有删除。我的脚本设法做到了这一点：

以下是事实：该模型称为“设置”，它作为一个单例实现：

class Setting(SingletonModel):
    page = models.IntegerField()
    profile = models.ForeignKey(Profile, on_delete=models.CASCADE, blank=True, null=True, default=None)
    addmonitored = models.BooleanField(default=True, verbose_name="Add shows as monitored to Sonnar")
    folders = models.BooleanField(default=True, verbose_name="Subfolders for seasons")

    def __str__(self):
        return "Settings"

    class Meta:
        verbose_name_plural = "Settings"

基本模型如下所示：

class SingletonModel(models.Model):
    class Meta:
        abstract = True

    def save(self, *args, **kwargs):
        self.pk = 1
        super(SingletonModel, self).save(*args, **kwargs)

    def delete(self, *args, **kwargs):
        pass

    @classmethod
    def load(cls):
        obj, created = cls.objects.get_or_create(pk=1)
        return obj

class SettingsFormSetView(UpdateView):
    model = Setting
    exclude = ['page', 'xxxxxx']

    template_name = 'settings.html'

    def get_object(self):
        return Setting.objects.get(pk=1)

    def get_success_url(self):
        return reverse('settings')

FormView如下所示：

class SingletonModel(models.Model):
    class Meta:
        abstract = True

    def save(self, *args, **kwargs):
        self.pk = 1
        super(SingletonModel, self).save(*args, **kwargs)

    def delete(self, *args, **kwargs):
        pass

    @classmethod
    def load(cls):
        obj, created = cls.objects.get_or_create(pk=1)
        return obj

class SettingsFormSetView(UpdateView):
    model = Setting
    exclude = ['page', 'xxxxxx']

    template_name = 'settings.html'

    def get_object(self):
        return Setting.objects.get(pk=1)

    def get_success_url(self):
        return reverse('settings')

我可以毫无问题地打开表单，输入数据，保存数据。我可以重新加载页面，但它仍然显示数据。如果我重新加载它几次，表单就会突然变空，并且该行（pk=1，这是该表中唯一的一行）也会从数据库中删除。 据我所知，没有其他东西在干扰。我别无选择，找不到问题的根源
