Django2:提交表单后,有没有更好的方法来“擦除”帖子以停止重新提交

我有一个django应用程序,在一个页面上,我有几个不同型号的表格。我想一个'成功'的消息,这是很容易做到的只是添加到上下文后,表单提交/验证。然而,这就留下了重新提交表单的可能性,这只会产生一个返回页面的错误,但它仍然让我恼火。

网址:

 url_patterns = [
      re_path(r'^manager/$', Manager.as_view(), name='manager'),

      .......more.....
 ]

视图.py:

class Manager(LoginRequiredMixin, View):

    template_name = 'results/manager_templates/manager.html'
    form1 = Form1
    form2 = Form2

    login_url = '/'
    redirect_field_name = 'redirect_to'


    def get(self, request, *args, **kwargs):

        form1 = self.form1()
        form2 = self.form2()

        context = {
                'form1': form1,
                'form2': form,}

        return render(request, self.template_name, context)


    def post(self, request, *args, **kwargs):

        submit_clicked = request.POST.get('submit')

        form1 = self.form1()
        form2 = self.form2()

        context = {}

        if submit_clicked == 'Form 1':

            form1 = self.form1(request.POST)

            if form1.is_valid():
                form1.save()

                context['message'] = 'Form 1 successful'

                # reset the form
                form1 = self.form1()

                # return HttpResponseRedirect(
                #            reverse('results:manager',
                #        ))


            else:
                print('NOT VALID')


        elif submit_clicked == 'Form 2':

             ... do same stuff as above ...


        context['form1'] = form1
        context['form2'] = form2

        return render(request, self.template_name, context)

如果我取消对HttpResponseRedirect out的注释,那么在验证并添加表单之后,如下所示:

               return HttpResponseRedirect(
                           reverse('results:manager',
                      ))

i、 e如果我要写:

               return HttpResponseRedirect(
                           reverse('results:manager',
                           kwargs={'success':'success'}
                      ))

Reverse for 'manager' with keyword arguments '{'success': 'success'}' not found. 1 pattern(s) tried: ['manager/$']

如果我改变了网址.py收件人:

 url_patterns = [
        re_path(r'^manager/$', Manager.as_view(), name='manager'),
        re_path(r'^manager/(?P<success>)$', Manager.as_view(), name='manager'),

 ] 

我得到一个错误:

 Reverse for 'manager' with keyword arguments '{'success': 'success'}' not found. 2 pattern(s) tried: ['manager/(?P<success>)$', 'manager/$']
