如何在Django中的框中显示烤面包机通知？

预期产出如下

视图.py

def UpdateProducts(request,id):
  if request.method == 'POST':
        form = ProductsForm(request.POST, request.FILES)
        if form.is_valid():
          data = Product.objects.get(pk=id)
          form = ProductsForm(request.POST,request.FILES, instance=data)
          form.save()
          messages.success(request, "The Subscriber has been successfully added")
          return redirect('/')

        else:
            messages.error(request, "Sorry the data has not been entered to the database")

Html

 {% for message in messages %}
   toastr.{{ message.tags }}({{ message }});
 {% endfor %}

请告诉我怎么做？

将图像直接添加到帖子中。你具体需要什么帮助？我没有10个名声，所以不能发布图片。实际上，烤面包机应该显示在带有关闭按钮的盒子中，并且应该在15秒内自动隐藏
