Question

我使用的是简单的数据表，但只要我使用get和laravel请求获取获取信息，Datatable就不能再在serverside上工作了：true。

JS

serverSide: true,
processing: true,
ajax: {
   url: "{!! route('listOfProjectsAjax') !!}",
   type: "GET",
   data: ajaxData,
   dataType: "JSON"
   },
columns: [...

控制器

public function ListOfprojects(Request $request)
  {
    $inputs = $request->all();
    return $this->projectRepository->getListOfProjects($inputs);
  }

存储库

  public function getListOfProjects($where = null)
  {


    $projectList = $this->project
      ->select( 'id','customer_name','project_name','otl_project_code','project_type','activity_type','project_status','meta_activity','region',
            'country','domain','description','estimated_start_date','estimated_end_date','comments','LoE_onshore','LoE_nearshore',
            'LoE_offshore','LoE_contractor','gold_order_number','product_code','revenue','win_ratio');
    $data = Datatables::of($projectList)->make(true);
    return $data;
  }

我不明白为什么。

我再次做了一些测试，并且当我有命令时，服务器端进行排序，搜索无效：

data: ajaxData,

来自我的ajax请求。

如果我删除它，那么一切正常，我可以进行服务器端搜索，排序，......

以下是来自服务器的2条回复：没有数据：ajaxData，：

使用数据：ajaxData，：

{"draw":0,"recordsTotal":6,"recordsFiltered":6,"data":[{"id":65,"customer_name":"cxc","project_name":"LAN1","project_type":"","activity_type":"","meta_activity":"","region":"","country":"","customer_location":"","domain":"","description":null,"estimated_start_date":"0000-00-00","estimated_end_date":"0000-00-00","comments":null,"LoE_onshore":0,"LoE_nearshore":0,"LoE_offshore":0,"LoE_contractor":0,"gold_order_number":"","product_code":"","revenue":0,"project_status":"","otl_project_code":"","win_ratio":0,"created_by_user_id":1,"otl_validated":0,"created_at":"2017-06-16 18:14:37","updated_at":"2017-06-16 18:14:37"},...}],"queries":[{"query":"select count(*) as aggregate from (select '1' as `row_count` from `projects` where not exists (select * from `activities` where `activities`.`project_id` = `projects`.`id`)) count_row_table","bindings":[],"time":0.83},{"query":"select * from `projects` where not exists (select * from `activities` where `activities`.`project_id` = `projects`.`id`)","bindings":[],"time":0.76}],"input":{"unassigned":"true"}}

这是我的ajaxData：

function ajaxData(){
          var obj = {
            'unassigned': 'true'
          };
          return obj;
        }

Answer 1

您的问题很可能与select('*')结合使用->make()有关。软件包维护者声明永远不要使用它，因为它可能导致意外行为。请阅读此示例顶部的警告：

https://datatables.yajrabox.com/fluent/basic

尝试将控制器更改为：

$projects = DB::table('projects')
            ->select(['id', 'field1', 'field2', 'created_at', 'updated_at']);

return Datatables::of($projects)->make();

示例还显示了使用'GET'请求而不是'POST'。你出于某种原因需要使用“POST”吗？您还可以使用请求输入优化任务服务器端，如下所示：

$projects = DB::table('projects')
            ->select(['id', 'field1', 'field2', 'created_at', 'updated_at'])
            ->where('unassigned', $request->input('unassigned'));

Answer 2

好吧，似乎发布数据的唯一方法就是这样做：

而不是使用：

data: ajaxData,

要使Laravel数据表正常工作，您需要使用：

data: function ( d ) {
                            d.unassigned = "true";
                        },

使用get或post时，Laravel数据表无法与serverside一起使用
