我正在将Tabulator与Django一起使用来编辑模型。对单元格进行任何更改之后，我将使用setData对使用Django REST Framework创建的REST端点进行Ajax调用。数据库更新正常。问题在于服务器的响应仅包含已更新的单个记录，这使得制表器数据减少为仅该记录。
我的问题是，如何让Tabulator忽略响应，否则在编辑后将数据留给其他人？
我在这方面（包括Django，尤其是JavaScript）非常陌生，如果我错过了一些基本的知识，我们深表歉意。
我的制表符代码如下。
function getCookie将按照Django文档here中的说明生成CSRF_TOKEN。然后将其作为header包含在'X-CSRFTOKEN': CSRF_TOKEN中。ajaxConfigPut用于将方法设置为PUT并包含CSRF_TOKEN，如上所述。然后，将其用于稍后在[table.setData）的table.setData(updateurl, updateData, ajaxConfigPut);调用中。ajaxResponse只是检查响应是否为数组（因为Tabulator期望使用一个适合GET的数组，但是PUT响应只是单个{}对象。因此，此函数强制执行PUT响应到由一个对象[{}]组成的数组中。 <div id="example-table"></div>
<script type="text/javascript">
// get CSRF token
// https://docs.djangoproject.com/en/dev/ref/csrf/#acquiring-the-token-if-csrf-use-sessions-and-csrf-cookie-httponly-are-false
function getCookie(name) {
var cookieValue = null;
if (document.cookie && document.cookie !== '') {
var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i++) {
var cookie = cookies[i].trim();
// Does this cookie string begin with the name we want?
if (cookie.substring(0, name.length + 1) === (name + '=')) {
cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
break;
}
}
}
return cookieValue;
}
var CSRF_TOKEN = getCookie('csrftoken');
// set variable to customise ajaxConfig for use in the setData call
var ajaxConfigPut = {
method:"PUT", //set request type to Position
headers: {
// "Content-type": 'application/json; charset=utf-8', //set specific content type
'X-CSRFTOKEN': CSRF_TOKEN,
},
};
//create Tabulator on DOM element with id "example-table"
var table = new Tabulator("#example-table", {
ajaxURL:"{% url 'cust_listapi' %}", // reverse pick up the url since in a django template (?)
height:205, // set height of table (in CSS or here), this enables the Virtual DOM and improves render speed dramatically (can be any valid css height value)
layout:"fitColumns", //fit columns to width of table (optional)
columns:[ //Define Table Columns

);
console.log(cell.getData());
var updateurl = "{% url 'cust_listapi' %}" + cell.getData().id + "/"
console.log('URL is: ' + updateurl)
// Create variable from full row data but drop the id;
console.log('About to create updateData')
var updateData = {};
updateData[cell.getField()] = cell.getValue();
console.log(updateData);
console.log('About to setData');
table.setData(updateurl, updateData, ajaxConfigPut);
console.log('Finished setData');
//cell.restoreOldValue();
},
ajaxResponse:function(url, params, response){
console.log('Beginning ajaxResponse')
console.log('The type is:', typeof(response));

我尝试修改端点的响应，以便返回数据库中的所有记录，但是这样做的问题是它不包括编辑，因此Tabulator表数据被覆盖。这是我在Django views.py中使用的代码。也许有一种方法可以返回已更改的数据？views.py
from rest_framework import generics, mixins from apps.app_mymodel.models import Customer from .serializers import CustomerSerializer class CustomerListAPIView(generics.ListAPIView): serializer_class = CustomerSerializer queryset = Customer.objects.all() class CustomerUpdateAPIView(generics.GenericAPIView, mixins.ListModelMixin, mixins.UpdateModelMixin): serializer_class = CustomerSerializer queryset = Customer.objects.all() # Override the put function here to return all records def put(self, request, *args, **kwargs): # return self.update(request, *args, **kwargs) return self.list(request, *args, **kwargs)这里是序列化器：serializers.py
from rest_framework import serializers from apps.app_mymodel.models import Customer class CustomerSerializer(serializers.ModelSerializer): class Meta: model = Customer fields = '__all__'有人能指出我正确的方向吗？
