コードは同じであり、それは私がこのことを理解していない理由です。

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) 

は、おそらくそれはRESPONSのステータスコードで何かを持っているが、それはそれを示さない理由画像がロードされたとき、それはどのようになります は、ここでは、投稿ページを訪問したときに、私のビュー機能は、それが使用されています一定？
