我正在使用 django 創建一個博客。我正在使用模型表單進行輸入。我想編輯現有的博客文章，但我無法讓它工作。models.pyclass tags(models.Model):name = models.CharField(max_length = 30)def __str__(self):    return self.nameclass Article(models.Model):    title = models.CharField(max_length=60)    post = HTMLField()    editor = models.ForeignKey(User,on_delete=models.CASCADE)    tag = models.ManyToManyField(tags,blank=True)    pub_date = models.DateTimeField(auto_now_add=True)    article_image = models.ImageField(upload_to='articles/', blank=True)    photo_credits = models.CharField(max_length=60,default='unsplash.com')Forms.pyclass UpdateArticleForm(forms.ModelForm):class Meta:    model = Article    fields = ['title','article_image','post','tags','photo_credits']Views.py@login_required(login_url='/accounts/login/')    def update_article(request,id):    instance = Article.objects.get(id = id)    if request.method == 'POST':        form = UpdateArticleForm(request.POST, request.FILES,instance=instance)        if form.is_valid():            form.save()            return redirect('index')    else:        form = UpdateArticleForm(instance=instance)    return render(request,'article/update.html',{'form':form})urls.pyurl(r'^article/update/$',views.update_article,name='update_article'),我收到 404 錯誤。如果我用下面的網址替換網址，我會得到一個Reverse for 'update_article' with no arguments not found. 1 pattern(s) tried: ['article/update/(?P<id>[0-9]+)/$']     url(r'^article/update/(?P<id>[0-9]+)/$',views.update_article,name='update_article'),我怎樣才能讓它工作？
