Django查看“else”语法

Question

我的django中有两个函数视图.py给我的问题。Django显示else行有一个语法错误，但我看不出它附近有任何问题（所有必需的函数等都已导入） 我需要一些帮助

@login_required         
def add_post(request, forumslug, threadslug):
    if request.method=='POST':
        form = PostForm(request.POST)
        if form.is_valid():
            user = request.user
            title = form.cleaned_data['title']
            body = form.closed_data['body']
            thread = get_object_or_404(Thread, slug=threadslug)
            forum = get_object_or_404(Forum, slug=forumslug)
            post = Post.objects.create(title=title, body=body, creator=user, thread=thread)
            url = '/%s/%s/' % (forumslug, slugify(title))
            return HttpResponseRedirect(url)
    else:
        form = PostForm()
        variables = RequestContext(request, {'form': form})
        return render_to_response('forum/new_post.html', variables)


@login_required    
def add_thread(request, forumslug):
    if request.method=="POST":
        form = PostForm(request.POST)
        if form.is_valid():
            user = request.user
            forum = get_object_or_404(Forum, slug=forumslug)
            title = form.cleaned_data['title']
            body = form.cleaned_data['body']
            thread = Thread.objects.create(title=title, slug=slugify(title), forum=forum, creator=user, body=body)
            url = '/%s/%s' % (forumslug, slugify(title))
            return HttpResponseRedirect(url)
    else:
        form = PostForm()
        variables = RequestConext(request, {'form': form})
        return render_to_response('forum/new_thread.html', variables)

Answer 1

行url = '/%s/%s/' % (forumslug, slugify(title)实际上缺少一个右括号，确定在else上方的行没有引发错误吗？在
