列表保持空

Question

我试图在代码中使用datables js，但是我的页面仍然是空的（没有标题和表）

我尝试了几次代码修改，但仍然保持空白页没有错误消息

html页：

   {% extends "baseCRM.html" %}
{% load bootstrap4 %}
<link rel="stylesheet" type="text/css" href="/static/DataTables/datatables.css">
<script type="text/javascript" charset="utf8" src="/static/DataTables/datatables.js"></script>

{% block content %}
     <table cellpadding="0" cellspacing="0" border="0" id="example">
        <thead>
            <tr><th>Client List</th></tr>
        </thead>
     <tbody></tbody>
    </table>


<script type="text/javascript" language="javascript" class="init">
     $(document).ready(function() {
         $('#example').dataTable( {
             "processing": true,
             "ajax": {
                 "processing": true,
                 "url": "{% url 'clientListJson' %}",
                 "dataSrc": ""
             },

             "columns": [
                     { "data": "fields.name" },
                     { "data": "pk" }
                 ]
         } );
     } );
 </script>

   {% endblock %}

你知道吗视图.py地址：

def client_list_json(request):
    object_list = Client.objects.all().order_by("name")
    json = serializers.serialize('json', object_list)
    return HttpResponse(json, content_type='application/json')

你知道吗型号.py你知道吗

class Client(models.Model):
    name = models.CharField(max_length=255,)
    description = models.CharField(max_length=255,blank=True)
    address1 = models.CharField("Address line 1",max_length=1024,)
    address2 = models.CharField("Address line 2",max_length=1024,)
    zip_code = models.CharField("ZIP / Postal code",max_length=12,)
    city = models.CharField("City",max_length=1024,)
    country = models.CharField("Country",max_length=3,choices=ISO_3166_CODES,)
    point_person = models.ForeignKey(User, limit_choices_to={'is_staff': True}, on_delete=models.CASCADE) # in charge of the client (admin)
    firm = models.ManyToManyField(Firm, related_name='Firm_Client',)

你知道吗网址.py你知道吗

path（'client\u list\u json/'，views.client\列表\u json，name='clientListJson'）

我应该有一份客户名单，包括姓名、描述、公司和联系人

这里我使用jQueryCDN，DataTableCDN。你知道吗

您的Ajax URL无法正常工作：

您的代码：

 "ajax": {
             "processing": true,
             "url": "{% url 'clientListJson' %}",
             "dataSrc": ""
         },

更新代码：

"ajax": {
             "processing": true,
             "url": "clientListJson",
             "dataSrc": ""
         },

Here are the full version of the code.

Html页面：我把它命名为anothor.html

another.html

{% extends "baseCRM.html" %}
{% load bootstrap4 %}

Views.py

def client_list_json(request):
    object_list = Client.objects.all().order_by("name")
    from django.core import serializers
    json = serializers.serialize('json', object_list)
    return HttpResponse(json, content_type='application/json')


def another(request):
    return render(request, 'anothor.html', context=None)

urls.py

为测试添加一个额外的URL。你知道吗

    path('another/', views.another, name='another'),
    path('another/clientListJson/', views.client_list_json, name='clientListJson'),
