ajax – 数据表：自定义响应处理

我开始在 AngularJS和 DataTables上工作,想知道是否可以自定义DataTables期待的响应.目前对DataTables插件的期望是这样的：

{
    "draw": 1,"recordsTotal": 57,"recordsFiltered": 5,"data": [...]
}

在服务器端,API正在由django-tastypie处理

服务器的响应是：

{
     Meta: {
        limit: 20,next: null,offset: 0,prevIoUs: null,total_count: 2
     },objects: [...]
 }

那么,有没有办法调整Datatables插件来接受/映射这个响应,否则我将不得不找到一个方法来添加预期的字段到api？

到目前为止我已经做到了：

var deptTable = angular.element('#deptManagementTable').DataTable({
        processing: true,serverSide: true,pagingType: "simple_numbers",ajax: {
            url: "/client/api/v1/departments/",data: function(d) {
                d.limit = d.length;
                d.offset = d.start;
                d.dept_name__icontains = d.search.value;
            },dataSrc: function(json) {
                for (var i=0,len=json.objects.length ; i<len ; i++) {
                    json.objects[i].DT_RowId = json.objects[i].dept_id;
                }
                return json.objects;
            }
        },aLengthMenu: [
            [5,25,50,100],[5,100]
        ],iDisplayLength: 5,columns: [
            {
                data: "dept_name"
            },{
                data: "dept_created_on",render: function ( data,type,full,Meta ) {
                    var dateCreated = new Date(data);
                    dateCreated = dateCreated.toLocaleDateString();
                    return dateCreated;
                }
            }
        ]
    });

任何帮助将不胜感激.

您可以将功能传递给DataTables ajax option,这将使您完全控制如何在将数据传递到DataTables之前获取和映射数据.

.DataTable({
    serverSide: true,ajax: function(data,callback,settings) {
        // make a regular ajax request using data.start and data.length
        $.get('/client/api/v1/departments/',{
            limit: data.length,offset: data.start,dept_name__icontains: data.search.value
        },function(res) {
            // map your server's response to the DataTables format and pass it to
            // DataTables' callback
            callback({
                recordsTotal: res.Meta.total_count,recordsFiltered: res.Meta.total_count,data: res.objects
            });
        });
    }
});

上述解决方案已经通过jQuery DataTables 1.10.4进行了测试.

由于这个问题是用Angular标记的,所以这里是使用angular-datatables的解决方案.

<div ng-controller="testCtrl">
    <table datatable dt-options="dtOptions" dt-columns="dtColumns" class="row-border hover"></table>
</div>

.controller('testCtrl',function($scope,$http,DTOptionsBuilder,DTColumnBuilder) {
    $scope.dtOptions = DTOptionsBuilder.newOptions()
        .withOption('serverSide',true)
        .withOption('ajax',function(data,settings) {
            // make an ajax request using data.start and data.length
            $http.get('/client/api/v1/departments/',{
                limit: data.length,dept_name__icontains: data.search.value
            }).success(function(res) {
                // map your server's response to the DataTables format and pass it to
                // DataTables' callback
                callback({
                    recordsTotal: res.Meta.total_count,data: res.objects
                });
            });
        })
        .withDataProp('data'); // IMPORTANT¹

    $scope.dtColumns = [
        // your column definitions here
    ];
});

上述解决方案已经使用角度数据表0.3.0 DataTable 1.10.4进行了测试.

¹这里要注意的重要部分是角度数据表解决方案要求.withDataProp(‘data’)可以工作,而纯jQuery DataTables解决方案没有数据：’data’选项.
