Python 我如何解决view blog.views.post#u细节问题'；t返回HttpResponse对象。它没有返回任何结果

请任何人帮助我解决此错误：查看

blog.views.post\u detail

没有返回

HttpResponse

对象。它返回了

None

相反，我已经尝试过检查，但仍然无法解决它

问题在于您对

返回的缩进。如果

，则应与第一个

一致：

 def post_detail(request, year, month, day, post):
    post = get_object_or_404(Post, slug=post,status='published', publish__year = year, publish__month = month, publish__day = day )
    comments = post.comments.filter(active=True)
    new_comment = None 
    if request.method == 'POST':
        comment_form = CommentForm(data=request.POST)
        if comment_form.is_valid():
            new_comment = comment_form.save(commit=False)
            new_comment.post = post
            new_comment.save()
        else:
            comment_form = CommentForm()
        return render (request, 'blog/post/detail.html', {'post':post,'comments':comments,'new_comment':new_comment, 'comment_form': comment_form ,})

当然，除非这个问题只是你的问题，而不是你的实际代码。但这将是检查/纠正的第一件事

 def post_detail(request, year, month, day, post):
    post = get_object_or_404(Post, slug=post,status='published', publish__year = year, publish__month = month, publish__day = day )
    comments = post.comments.filter(active=True)
    new_comment = None 
    if request.method == 'POST':
        comment_form = CommentForm(data=request.POST)
        if comment_form.is_valid():
            new_comment = comment_form.save(commit=False)
            new_comment.post = post
            new_comment.save()
    else:
       comment_form = CommentForm()
    return render (request, 'blog/post/detail.html', {'post':post,'comments':comments,'new_comment':new_comment, 'comment_form': comment_form ,})

这是正确的代码。我已经修复了这个错误。
问题是我没有在if块下渲染。
我用代码修复了它。else块假定位于第一个if块之外。
def post_detail(request, year, month, day, post):
    post = get_object_or_404(Post, slug=post,status='published', publish__year = year, publish__month = month, publish__day = day )
    comments = post.comments.filter(active=True)
    new_comment = None 
    if request.method == 'POST':
        comment_form = CommentForm(data=request.POST)
        if comment_form.is_valid():
            new_comment = comment_form.save(commit=False)
            new_comment.post = post
            new_comment.save()
            return HttpResponseRedirect('/success/')
    else:
        comment_form = CommentForm()
    return render (request, 
                    'blog/post/detail.html', 
                    {'post':post,
                    'comments':comments,
                    'new_comment':new_comment, 
                    'comment_form': comment_form ,})
