我是 django 的新手，我第一次使用 ajax 和 django。我尽力在这里和那里搜索，但我无法找到解决方案

这个答案也没有帮助

我得到的错误是

Method Not Allowed (POST): /post/like/
[07/Jun/2019 16:06:16] "POST /post/like/ HTTP/1.1" 405 0

下面是代码

likes_section.html

{% if request.user.is_authenticated %}
<form  action="{% url 'like_post' %}" method="post">
  {% csrf_token %}

  {% if is_liked %}
  <span class="mr-2" style="color:black;">{{ post.total_likes }} Like{{ post.total_likes|pluralize }}<button type="submit" id="like_the_post_by_user" class="btn btn-primary ml-2" name="post_id" value="{{ post.id }}">DisLike</button></span>
  {% else %}
  <span class="mr-2" style="color:black;">{{ post.total_likes }} Like{{ post.total_likes|pluralize }}<button type="submit" id="like_the_post_by_user" class="btn btn-primary ml-2" name="post_id" value="{{ post.id }}">Like</button></span>
  {% endif %}
</form>
{% else %}
  <span class="mr-2">{{ post.total_likes }} Like{{ post.total_likes|pluralize }}<button type="submit" id="like_the_post_by_user" class="btn btn-primary ml-2" name="post_id" value="{{ post.id }}" disabled>Like</button>Please Login to enable Like button</span>
{% endif %}

$(document).ready(function(event){
    $(document).on('click',"#like_the_post_by_user", function(event){
      event.preventDefault();
      console.log($("#like_the_post_by_user").val())
      console.log("from jquery section")
      var pk = $(this).attr('value');
      $.ajax({
        type : "POST",
        url : "{% url 'like_post' %}",
        data : {'id': pk , "csrfmiddlewaretoken": '{{ csrf_token }}' },
        dataType : 'json',
        success : function(response){
          $('#like-section_user').html(response['form'])

        },
        error : function(rs, e){
          console.log(rs.responseText);

        html = render_to_string('blog/likes_section.html', context, request=request)
        return JsonResponse({"form":html})

任何帮助将不胜感激！

您的“/post/like” URL 与 CategoryListView 的 URL 模式匹配，因为它是“post”加上一个字符串。

正如您对帖子详细信息视图所做的那样，将 like 视图的模式放在 URL 列表的前面，以便它首先匹配。
