Submit a form but stay on the page and the form changes

I would like to put a Poll Voting Form on any page like a blog post page or the homepage.
Here is the page that I display the form and the view that it gets posted to in the form action attribute.
I would like to be able to submit the form but stay on that page and have the form change into the results or a link to the results.

class DetailView(PublishedMixin, generic.DetailView):      model = Poll      template_name = 'polls/detail.html'        def get_context_data(self, **kwargs):          context = super(DetailView, self).get_context_data(**kwargs)          context['form'] = PollForm(instance=self.get_object())          return context    <form action="{% url 'polls:vote' poll.id %}" method="post">  {% csrf_token %}  {{form.as_p}}  <input type="submit" value="Vote" />  </form>

class VoteView(PublishedMixin, generic.DetailView):      model = Poll        '''      def get_form(self, *args, **kwargs):          form = PollForm(instance=self.get_object())          #return super(VoteView, self).get_form(*args, **kwargs)          return form      '''      @property      def success_url(self):          return reverse(              'polls:results', args=(self.get_object().id,))        def post(self, request, *args, **kwargs):          form = PollForm(request.POST, instance=self.get_object())          if form.is_valid():              selected_choice = form.cleaned_data['choice']              selected_choice.votes += 1              selected_choice.save()                        return HttpResponseRedirect(request.META['HTTP_REFERER'])  





I also thought about doing a mixin on the page, but I can't just render the page with the form attribute equal to something else, becuase I would need to redirect to avoid the refresh problem.


class PollFormMixin(SingleObjectMixin):      """      puts form and "view results link" in context      and validates and saves the form      """      model = Poll        def get_context_data(self, **kwargs):          context = super(PollFormMixin, self).get_context_data(**kwargs)          form = PollForm(instance=self.get_object())          context['form'] = form          return context        def post(self, request, *args, **kwargs):          form = PollForm(request.POST, instance=self.get_object())          if form.is_valid():              form.save()              return HttpResponseRedirect(self.success_url)          else:              return render(request, self.template_name,                  {'form': form, 'poll': self.get_object()})  

class VoteView(PublishedPollMixin, PollFormMixin, DetailView):      """      Vote on a poll      """      model = Poll      template_name = 'polls/detail.html'        @property      def success_url(self):          return reverse(              'polls:results', args=(self.get_object().id,))
