обратная функция не работает в HitcountDetailView в django?

Question

Я пытаюсь прикрепить форму информационного бюллетеня к моей странице postdetail (HitcountDetailView), я попробовал Formmixin, и моя регистрация информационного бюллетеня работала правильно, но перенаправление URL-адреса не работает.

* 1002 аргументы ключевого слова '{' id ':,' slug ':' jobs-available-96 '}' не найдены. Пробовали 1 шаблон (ы): ['blog \ / details \ / (? P [-a-zA-Z0-9 _] +) \ / (? P [0-9] +) \ / $']

views.py

class Blog_Detail(FormMixin,HitCountDetailView):
    model=BlogPost
    template_name = 'blog/blogDetail.html'
    context_object_name = 'posts'
    slug_field = 'slug'
    count_hit = True
    id=id
    form_class=NewsletterForm

    def get_success_url(self,id=None):
        if 'slug' in self.kwargs:
            slug = self.kwargs['slug']
        else:
            slug = 'demo'
            return reverse('details', kwargs={"id":self.id,'slug': slug})

    def get_context_data(self, **kwargs):
        instance = super(Blog_Detail, self).get_context_data(**kwargs)
        instance['form'] = NewsletterForm()
        instance.update({
        'popular_posts': BlogPost.objects.order_by('-hit_count_generic__hits')[:3],
        'recent_posts': BlogPost.objects.filter().order_by('-updated')[:3],
        })
        return instance

    def post(self,request, *args, **kwargs):
        form=NewsletterForm(request.POST or None)
        if form.is_valid():
            instanceMail=form.save(commit=False)
            if NewsletterUser.objects.filter(email=instanceMail.email).exists():
                messages.warning(request,"Your Email is aldready exists")
                self.get_success_url()

            else:
                instanceMail.save()
                messages.success(request,"Your Email" +"\t" +instanceMail.email ))
                subject="Thank you for Joining in JOBvsJOB"
                from_email=settings.EMAIL_HOST_USER
                to_email=[instanceMail.email]
                d={}
                html_templatey=get_template("blog/UserSubscribeMail.html").render(d)
                welcomemessage="Welcome"
                email=EmailMultiAlternatives(subject,'',from_email,to_email)
                email.attach_alternative(html_templatey,'text/html')
                email.send()
                self.get_success_url()
                form=NewsletterForm()

        args={"form":form}
        return render(request,'blog/blogDetail.html',args)

urls.py

urlpatterns=[
    path('details/<slug:slug>/<int:id>/',views.Blog_Detail.as_view(),name="details"),
]

slugfield и обратные методы в models.py

def get_absolute_url(self):
    return reverse('details',kwargs={"id":self.id,"slug":self.slug})

def save(self,*args,**kwargs):
    self.slug=slugify(self.postTitle) + "-" + str(self.id)
    super().save(*args,**kwargs)
