django 使用datatables的服务器模式

需要在url中配置路由，/work/list/指向到work_list

JS代码：

 $(document).ready(function() {

    $("#dataTables-example").dataTable(
        {
            // 开启服务器模式
            "serverSide": true,
            // 开启处理功能
            "processing" : true,
            // 允许排序
            "orderable":true,
            // 允许查询
            "searching" : true,
             // 根据第四列降序排列
            "order": [[ 3, "desc" ]],
            // 发送post请求
            "ajax":{
                "type": 'POST' ,
                "url": '/work/list/'
            },
            // 返回数据
            columns: [
                { "data": "name",
                    // 数据渲染，返回超链接的字条
                    "render": function ( data, type, full, meta ) {
                        return '<a href="/work/work_results?name='+data+'" ><span>'+data+'</span></a>';
                }
                },
                { "data": "user" },
                { "data": "fun" },
                { "data": "start_time" },
                { "data": "end_time" },
                { "data": "sum_time" },
                { "data": "status",
                    // 数据渲染，判断返回内容，返回span颜色
                    "render": function (data, type, full, meta) {
                        if (data == '执行成功') {
                            return '<span class="label label-success">' + data + '</span>';
                        }
                        else if (data == '执行失败') {
                            return '<span class="label label-danger">' + data + '</span>';
                        }
                        else if (data == '执行中') {
                            return '<span class="label label-warning">' + data + '</span>';
                        }
                        else {
                            return '<span class="label label-primary">' + data + '</span>';
                        }
                    }}
            ],
            'columnDefs': [{
                'targets': 0,
                'searchable': true
        }]

        }

    );
});

    
  $("form").submit(function(e){
    e.preventDefault();
    table = $("#dataTables-example").DataTable();
    table.ajax.reload();
});

国际化

$(function() {
    var oLanguage = {
        "oAria": {
            "sSortAscending": ": 升序排列",
            "sSortDescending": ": 降序排列"
        },
        "oPaginate": {
            "sFirst": "首页",
            "sLast": "末页",
            "sNext": "下页",
            "sPrevious": "上页"
        },
        "sEmptyTable": "没有相关记录",
        "sInfo": "第 _START_ 到 _END_ 条记录，共 _TOTAL_ 条",
        "sInfoEmpty": "第 0 到 0 条记录，共 0 条",
        "sInfoFiltered": "(从 _MAX_ 条记录中检索)",
        "sInfoPostFix": "",
        "sDecimal": "",
        "sThousands": ",",
        "sLengthMenu": "每页显示条数: _MENU_",
        "sLoadingRecords": "正在载入...",
        "sProcessing": "正在载入...",
        "sSearch": "",
        "sSearchPlaceholder": "",
        "sUrl": "",
        "sZeroRecords": "没有相关记录"
    }
    $.fn.dataTable.defaults.oLanguage = oLanguage;
});

table表代码

<table class="table table-striped table-hover" id="dataTables-example">
    <colgroup>
        <col style="width:8%">
        <col style="width:4%;">
        <col style="width:2%;">
        <col style="width:6%;">
        <col style="width:4%;">
        <col style="width:4%;">
        <col style="width:4%;">
    </colgroup>
    <thead>
        <tr>
            <th>作业名称</th>
            <th>执行人</th>
            <th>执行方式</th>
            <th>开始时间</th>
            <th>结束时间</th>
            <th>总耗时</th>
            <th>作业状态</th>
        </tr>
   </thead>
   <tbody>
   </tbody>
</table>

后端代码：

def work_list(request):
    from django.db.models import Q
    if request.method == "POST":
        # 获取所有数据
    all_result = running_list.objects.all().order_by("-start_time")
