Question

我正在使用laravel datatable包，一切正常。我有关系列搜索的问题。让我详细说明一下：我有两张桌子：
ed_class（主要表）
ed_section（二级表）

这里是上表的结果与它们之间的关系。

主要数据来自ed_section表，并通过建立关系我从ed_class表获取类名。由于数据来自ed_section表，因此数据表列搜索在节名列上工作正常，但它不能在类名列上工作，那么如何在类名列上实现搜索。？

这里有数据表js代码：

$(function() {
    $('#table').DataTable({
        "pageLength": 25,
         "ordering": false,
        //"columnDefs": [{
        //"targets": 7,
        //"orderable": false
        //}],
        processing: true,
        serverSide: true,
        ajax: '{!! url('sections/data') !!}',
        columns: [
            { data: 'sr_no', name: 'sr_no' },
            { data: 'classid', name: 'classid' },
            { data: 'sectiontitle', name: 'sectiontitle' },
            { data: 'Option', name: 'Option' }
        ]
    });
});

这里是服务器端代码（使用laravel datatable包）：

public function data(){

    $model = Section::all();
    $data =  Datatables::of($model);
    $data = $data->addColumn('sr_no', function(Section $section){

            })->editColumn('classid', function(Section $section){
                return $section->studentClass->classtitle;
            })->addColumn('Option', function(Section $section) {
                return '<div class="btn-group">
              <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                Action <span class="caret"></span>
              </button>
              <ul class="dropdown-menu dropdown-menu-left">
                <li><a class="edit_section" data-id='.$section->sectionid.'> <i class="fa fa-edit" data-toggle="tooltip" title="" data-original-title="Edit"></i> Edit</a></li>
                <li role="separator" class="divider"></li>
                <li><a href="'.url('/delete_sections/' . $section->sectionid).'" onclick="return confirm(\'Are you sure you want to remove this Section? \')" data-action="delete"> <i class="fa fa-trash-o" data-toggle="tooltip" title="" data-original-title="Delete"></i> Delete</a></li>
              </ul>
            </div>';
            })->rawColumns(['Option']);

    $sections = $data->make(true);

    return $sections;

}

这是模特关系：

class Section extends Model {

public function studentClass(){
    return $this->belongsTo('App\Classes','classid','classId');
  }

}

I have find solution and want to share so that it can help others too:

Here's server side code in controller (using laravel datatable package):

public function data(){

    $model = Section::with('studentClass');
    $data =  Datatables::of($model);
    $data = $data->addIndexColumn()
            ->editColumn('classid', function(Section $section){
                return $section->studentClass->classtitle;
            })->addColumn('Option', function(Section $section) {
                return '<div class="btn-group">
              <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                Action <span class="caret"></span>
              </button>
              <ul class="dropdown-menu dropdown-menu-left">
                <li><a class="edit_section" data-id='.$section->sectionid.'> <i class="fa fa-edit" data-toggle="tooltip" title="" data-original-title="Edit"></i> Edit</a></li>
                <li role="separator" class="divider"></li>
                <li><a href="'.url('/delete_sections/' . $section->sectionid).'" onclick="return confirm(\'Are you sure you want to remove this Section? \')" data-action="delete"> <i class="fa fa-trash-o" data-toggle="tooltip" title="" data-original-title="Delete"></i> Delete</a></li>
              </ul>
            </div>';
            })->rawColumns(['Option']);

    $sections = $data->make(true);

    return $sections;

}

Here's datatable js code:

$(function() {
    $('#table').DataTable({
        "pageLength": 25,
         "ordering": false,
        "columnDefs": [
        { "searchable": false, "targets": [0,3] }
        ],
        processing: true,
        serverSide: true,
        ajax: '{!! url('sections/data') !!}',
        columns: [
            { data: 'DT_Row_Index', name: 'DT_Row_Index' },
            { data: 'classid', name: 'studentClass.classtitle' },
            { data: 'sectiontitle', name: 'sectiontitle' },
            { data: 'Option', name: 'Option' }
        ],
        "oLanguage": {
        "sSearch": "Search Class: "
        }
    });
});

Answer 2

尝试这样

 $orders = Order::with('user');
    return Datatables::of($orders)
        ->addColumn('user', function ($order) {
            return $order->user->->name;
        })

视图中：

  { "data": "user" , name : "user.name"},
