Django：让用户从默认模型用户中删除自己的用户实例

Question

我有一个模型Creator，它通过OneToOneField 字段链接到Django 标准User 模型。 Creator 模型可以让我在添加/编辑Creator 的信息时更加灵活。现在为了删除Creator，我使用通用的DeleteView。但是，这不会删除 User 实例，因此不完全是我想要做的（例如，已删除的 Creator 的用户名是“已被占用”）。 有没有办法使用默认的DeleteView 让用户删除他的帐户？ 关于删除User 实例，注销帐户，执行“删除帐户”操作的最佳做​​法是什么？用户，并确认操作成功？

到目前为止我尝试了什么：

models.py

class Creator(models.Model):
    first_name = models.CharField(max_length=100, null=True, blank=True)
    last_name = models.CharField(max_length=100, null=True, blank=True)
    street_and_number = models.CharField(max_length=200, null=True, blank=True)
    zip_code = models.CharField(max_length=30, null=True, blank=True)
    location = models.CharField(max_length=100, null=True, blank=True)
    state_province = models.CharField(max_length=100, null=True, blank=True)
    country = models.CharField(max_length=100, null=True, blank=True)

    user = models.OneToOneField(User, on_delete=models.CASCADE)

    slug = models.SlugField()

    def save(self, *args, **kwargs):
        self.slug = slugify(self.user)
        super(Creator, self).save(*args, **kwargs)

    def get_absolute_url(self):
        return reverse('creator-detail', args=[str(self.slug)])

views.py

class CreatorDelete(LoginRequiredMixin, DeleteView):
    #model = User # does not work
    model = Creator
    success_url = reverse_lazy('index')

    # these two methods only give access to the users own profile but not the others
    def user_passes_test(self, request):
        if request.user.is_authenticated:
            self.object = self.get_object()
            return self.object.user == request.user
        return False

    def dispatch(self, request, *args, **kwargs):
        if not self.user_passes_test(request):
            return redirect_to_login(request.get_full_path())
        return super(CreatorDelete, self).dispatch(request, *args, **kwargs)

urls.py

path('creator/<slug:slug>/delete/', views.CreatorDelete.as_view(), name='creator-delete')

另外this thread 似乎很有希望，但由于我想使用user_confirm_delete.html 模板而不是基于类的视图（实现检查用户只能删除他自己的帐户）我没有设法让它工作。

将 delete() 方法重写为，

class CreatorDelete(LoginRequiredMixin, DeleteView):
    .....
    .....
    .....

    # your code

    def delete(self, request, *args, **kwargs):
        self.object = self.get_object()
        self.object.user.delete()  # deleting the default "User" model
        return HttpResponseRedirect(reverse('index'))
