I'm coding a news site.Now I'm detailing with the comment post function.And meet the issue says:
Reverse for 'update_comment' with arguments '('',)' not found. 1 pattern(s) tried: ['comment\\/(?P<news_pk>[0-9]+)$']
I have tried many ways and times but still can't solve it and I can't find any wrong with my code.And really need your help.
The comment post function is in the news_detail.html. There are two important apps in my project news and operation comment models is under operation
Here is my root urls.py:
path('news', include(('news.urls', 'news'), namespace="news")), path('', include(('operation.urls', 'operation'), namespace="operation")),
Here is the news/urls.py
path('-<int:news_pk>', newsDetailView, name="news_detail")
Here is the operation/urls.py:
path('comment/<int:news_pk>', views.update_comment, name="update_comment"),
Here is the news/view.py
def newsDetailView(request, news_pk): news = News.objects.get(id=news_pk) title = news.title author = news.author_name add_time = news.add_time content = news.content category = news.category tags = news.tag.annotate(news_count=Count('news')) all_comments = NewsComments.objects.filter(news=news) return render(request, "news_detail.html", { 'title': title, 'author': author, 'add_time': add_time, 'content': content, 'tags': tags, 'category': category, 'all_comments': all_comments, })
Here is operation/views.py
def update_comment(request, news_pk): news = News.objects.get(id=news_pk) comment_form = CommentForm(request.POST or None) if request.method == 'POST' and comment_form.is_valid(): if not request.user.is_authenticated: return render(request, 'login.html', {}) comments = comment_form.cleaned_data.get("comment") news_comment = NewsComments(user=request.user, comments=comments, news=news) news_comment.save() return render(request, "news_detail.html", { 'news_comment': news_comment, 'news':news })
And here is the news_detail.html:
{% if user.is_authenticated %} <form method="POST" action="{% url 'operation:update_comment' news.pk %}">{% csrf_token %} <textarea id="js-pl-textarea" name="comment"></textarea> <input type="submit" id="js-pl-submit" value="发表评论"></input></form>
