Comments not registering into database when submitting form
问题
当我尝试通过我的表单添加评论时，页面会正确重定向，但不会渲染/添加评论。
在尝试添加评论时，我在终端中收到以下错误信息：
来自（'127.0.0.1'，55445）的损坏管道

template_name = 'view-post.html'
post = get_object_or_404(BlogPost, slug=slug)

if request.method == 'POST':
comment_form = CommentForm(request.POST)
if comment_form.is_valid():
# 创建评论对象，但暂时不保存到数据库

# 将当前帖子分配给评论
user_comment.post = post
# 将评论分配给用户

你的表单中没有设置任何网址。我猜想你的表单只是发送到 viewpost，而这个页面没有包含任何POST处理，所以你会再次显示相同的页面。
英文:
You do not set any url in your form. I suppose your form is just sent to viewpost which not contains any POST process so, you display again same page.
