Django（Python）AttributeError：'NoneType'對象沒有'split'屬性

Question

當我訪問帖子頁面時出現奇怪的錯誤。我製作的Web應用程序可以發佈圖片和視頻。隨着圖像它做工精細，但當我發佈的視頻，然後前往該頁面，服務器給我下面的輸出：

代碼的圖像和視頻是相同的，這就是爲什麼我不明白這一點。 這裏是我的查看功能，當您訪問後網頁時使用：

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) 

也許這與在respons狀態代碼的東西，但它爲什麼不顯示它的圖像加載時，以及它如何能固定？
