Django Ajax форма не отправляется и страница зависает

1 голос
/ 30 апреля 2020

Я пытаюсь отправить форму, используя Ajax, однако после нажатия кнопки отправки я вижу, что мое представление успешно вызывается в терминале, но сообщение об успехе не распечатывается, и страница зависает. Я предполагаю, что мой ajax звонок застревает.

моя форма: 

 <form method="POST" data-url="{% url 'home:post-detail' guid_url %}" class="post-comment-form" style="height: 1rem;">
              {% csrf_token %}
              <div class="input-group">
                {{ form }}
                <div class="input-group-append">
                  <button class="btn btn-sm small btn-outline-primary ml-1" style="height: 2.3rem; border-radius: 20px; text-decoration: none;" type="submit">Add</button>
                </div>
              </div>     
            </form>

моя ajax функция: РЕДАКТИРОВАТЬ 

$('.post-comment-form').on('submit', function (e) {
    e.preventDefault();
    e.stopImmediatePropagation();
    var form = $(this).serialize();
    $.ajax({
      url: $(this).attr('data-url'),
      type: $(this).attr('method'),
      data: form,
      dataType: 'json',
      success: function(data) {
        $("#post-linked-comments div").html(data.comments); // This line is causing the page to be unresponsive
        console.log("successfully submitted form")
        $('textarea').val('');
        $('.reply-btn').on("click", function () {
          $("#modal-comment-reply textarea").attr("placeholder","Add your reply")
          $("#modal-comment-reply textarea").addClass("comment-reply-adjust")
          var c_id = $(this).data('id');
          $("#c-get-id").val(c_id);
          $('textarea').val('');
          $("#modal-comment-reply").modal("show");
          });
          $('.view-replies').on('click', function () {
          var h = $(this).data('hidden');
          var curr = $(this).text()
          var newt = $(this).attr('text')
          $(this).text(newt)
          $(this).attr("text",curr)
          var id = $(this).data('id');
          if(h == 1){
            $("#c-"+id).show();
            $(this).data('hidden',0);
            } else {
            $("#c-"+id).hide();
            $(this).data('hidden',1);
            }
          });
      },
      error: function(rs, e){
                console.log(rs.responeText);
            },
    });
  });

Я уже пробовал: 

 $('.post-comment-form').on('submit', function (e) {});

мой взгляд на обработку функции: 

 @login_required
def post_detail(request, guid_url):
    data = dict()
    post = get_object_or_404(Post, guid_url=guid_url)
    comments = Comment.objects.filter(post=post,reply=None)
    if request.method == 'POST':
        form = CommentForm(request.POST or None)
        if form.is_valid():
            comment = form.save(False)
            reply_id = request.POST.get('comment_id')
            comment_qs = None
            if reply_id:
                comment_qs = Comment.objects.get(id=reply_id)
            comment.name = request.user
            comment.post = post
            comment.reply = comment_qs
            comment.save()
        else:
            data['is_valid'] = False
    else:
        form = CommentForm()
    guid_url = post.guid_url
    comment_count = post.comment_count()
    context = {'post':post,
                'form':form,
                'comments':comments,
                'comment_count':comment_count,
                'guid_url':guid_url,
                }
    if request.is_ajax():
        data['comments'] = render_to_string('home/posts/post_comment.html',context,request=request)
        return JsonResponse(data)
    return render(request,'home/posts/post_detail.html',context)

РЕДАКТИРОВАТЬ Мой шаблон для загрузки комментариев:

в post_detail. html: 

<div id="post-linked-comments" class="pb-1" style="margin: 0;">
        <div>
          {% include 'home/posts/post_comment.html' with comments=comments %}
        </div>    
      </div>

и мой postpost_comment. html:

Я добавил еще файлы. Я нашел причину ошибки, но я не знаю, что ее вызывает. Если я удаляю эту строку, комментарий добавляется, но мне нужно обновить страницу sh, чтобы увидеть ее.
