def valpost(request, slug = None):
    instance = get_object_or_404(Post, slug=slug)
    comments = Comment.objects.all()
    form = CommentForm()
    if request.method == 'POST'
        form = CommentForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect(<success page>)
  context = {
    "title": instance.title, 
    "instance" : instance,
    "form": form,
    "comments" : comments,
  }
  template = 'post_detail.html'
  return render(request, template, context)
