使用 ajax 作为注释表单，它给了我 500 个内部错误，但没有脚本它可以工作，这意味着我的脚本是错误的;对

我有有效的评论系统（至少在后端工作）。问题是每次用户提交评论时，页面都会刷新。我为此编写了一个 ajax 函数，但由于我是初学者，我本以为会出现错误，我做到了。我有 500 个内部错误。我不确定我做错了什么。这是我的代码

<div class='reply_comment'>
        <form method="POST" action='{% url "comment_create" %}'>{% csrf_token %}
        <input type='hidden' name='post_id' id='post_id' value='{% url "comment_create" %}'/>
        <input type='hidden' name='origin_path' id='origin_path' value='{{ comment.get_origin }}'/>
        <input type='hidden' name='parent_id' id='parent_id' value='{{ comment.id }}' />
        {% crispy comment_form comment_form.helper %}
        </form>
        </div>

<script>
 $(document).on('submit','.commentForAjax', function(e){
  e.preventDefault();
  $.ajax({
    type:'POST',
    url:'/comment/create',
    data:{
      post_id:$('#post_id').val(),
      origin_path:$('origin_path').val(),
      parent_id:$('#parent_id').val(),
      csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val()
    },
    success:function(){
      alert('it worked');
    }
  })
 })
</script>

我有这样的网址

   url(r'^comment/create/$', 'comment_create_view', name='comment_create'),

编辑：

我没有发布我的 views.py，因为它很大，并认为我写错了ajax。我会发布我的观点

def comment_create_view(request):
    if request.method == "POST" and request.user.is_authenticated():
        parent_id = request.POST.get('parent_id')
        post_id = request.POST.get("post_id")
        origin_path = request.POST.get("origin_path")
        try:
            post = Post.objects.get(id=post_id)
        except:
            post = None
        parent_comment = None
        if parent_id is not None:
            try:
                parent_comment = Comment.objects.get(id=parent_id)
            except:
                parent_comment = None
            if parent_comment is not None and parent_comment.post is not None:
                post = parent_comment.post
        form = CommentForm(request.POST)
        if form.is_valid():
            comment_text = form.cleaned_data['comment']
            if parent_comment is not None:
                # parent comments exists
                new_comment = Comment.objects.create_comment(
                    user=MyProfile.objects.get(user=request.user),
                    path=parent_comment.get_origin, 
                    text=comment_text,
                    post = post,
                    parent=parent_comment
                    )
                #affected_users = parent_comment.get_affected_users()
                #print "this is"
                affected_users = parent_comment.get_affected_users()
                return HttpResponseRedirect(post.get_absolute_url())
            else:
                new_comment = Comment.objects.create_comment(
                    user=MyProfile.objects.get(user=request.user),
                    path=origin_path, 
                    text=comment_text,
                    post = post
                    )
                return HttpResponseRedirect(post.get_absolute_url())
        else:
            messages.error(request, "There was an error with your comment.")
            return HttpResponseRedirect(origin_path)
    else:
        raise Http404

我忘了在这里添加这个

urlpatterns += patterns('comments.views',

编辑二，我使用 class for commentForAjax 而不是 id 的原因是因为我也想对我的回复注释代码产生相同的效果。我想要一个 ajax 函数用于我的两个表单。

<div class="make_reply">
    <a href='#' class='reply_btn'>reply</a>
        <div class='reply_comment'>
        <form method="POST" action='{% url "comment_create" %}'>{% csrf_token %}
        <input type='hidden' name='post_id' id='post_id' value='{% url "comment_create" %}'/>
        <input type='hidden' name='origin_path' id='origin_path' value='{{ comment.get_origin }}'/>
        <input type='hidden' name='parent_id' id='parent_id' value='{{ comment.id }}' />
        {% crispy comment_form comment_form.helper %}
        </form>
        </div>
    </div>

编辑：这是我的 Django 错误，我不知道该怎么做，但遵循了丹尼尔的指导。是这个吗？运行时错误在/comment/create您通过 POST 调用了此 URL，但该 URL 不以斜杠结尾，并且您已设置APPEND_SLASH。Django 在维护 POST 数据时无法重定向到斜杠 URL。将表单更改为指向 127.0.0.1：8000/comment/create/（注意尾部斜杠），或在 Django 设置中设置 APPEND_SLASH=False。
