comment.html：

    <form method="POST" class="post-form">{% csrf_token %}

看起来你早早从post_detail_view回来了。试试这个：

def post_detail_view(request,year, month, day, post):

    post = get_object_or_404(Post,slug=post,
                          status='published',
                          publish__year=year,
                          publish__month=month,
                          publish__day=day)

    comments = post.comments.filter(active=True)
    if request.method == 'POST':
        form = CommentForm(request.POST)
        if form.is_valid():
          new_comment = form.save(commit=False)
          new_comment.post = post
          new_comment.save()
    else:
        form = CommentForm()
    return render(request,'post/comment.html',{'post':post,
                                           'comments': comments,
                                           'form':form})

django表单不显示在页面上
