嗨，我正在尝试查看个人资料页面articles/profile/<int:author_id>

当我添加个人资料页面链接时，导航栏不起作用。如果我articles:profile article.author_id从navbar.html所有链接中删除有效。我的错误信息在这里：

NoReverseMatch at / Reverse for 'profile' with arguments '('',)' 未找到。尝试了 1 种模式：['articles/profile/(?P<author_id>[0-9]+)$']

视图.py

def profile(request,author_id):
    article = get_object_or_404(Article,author_id = author_id)
    context = {
        "article":article,
    }

    form = ArticleForm(request.POST or None,request.FILES or None)

    if form.is_valid():
        article = form.save(commit=False)
        
        article.author = request.user
        article.save()
        
        messages.success(request,"Dosya Yüklendi")
        return redirect("article:dashboard")

    return render(request,"profile.html",{"article":article,'form':form})

导航栏.html
