Django(Python)AttributeError：’NoneType’对象没有属性’split’

概述我访问帖子页面时遇到奇怪的错误.我制作了一个可以发布图像和视频的Web应用程序.使用图像它工作正常,但当我发布视频并转到其页面时,服务器给我以下输出： Traceback (most recent call last): File "C:\Users\Slavko\AppData\Local\Programs\Python\Python35-32\lib\wsgiref\handlers.py 我访问帖子页面时遇到奇怪的错误.我制作了一个可以发布图像和视频的Web应用程序.使用图像它工作正常,但当我发布视频并转到其页面时,服务器给我以下输出：

图像和视频的代码是相同的,这就是为什么我不明白这一点.
这是我的查看功能,当您访问帖子页面时使用：

def post_info(request,pk):    form = CommentForm(request.POST or None)    post = get_object_or_404(Post,pk=pk)    same_author_posts = Post.objects.filter(author=post.author)    if request.method == 'POST':        if form.is_valID():            instance = form.save(commit=False)            instance.author = request.user            instance.post = post            instance.save()            form = CommentForm()            messages.success(request,'Comment is approved!')            return httpResponseRedirect('/post/%s/'%(pk))        else:            messages.error(request,'Comment is not valID!')            return httpResponseRedirect('/post/%s/'%(pk))    context = {        'form': form,'post': post,'same_author_posts': same_author_posts,}    return render(request,'post/post_info.HTML',context)

可能它在响应中有状态代码,但为什么它不会在加载图像时显示它以及如何修复它？

解决方法 尝试在禁用防火墙/防病毒的情况下运行它 总结
