Php Laravel 5.2 w/Yajra datatables，在对象的Read视图中，如何显示父模型的hasMany子模型的所有datatables？

父模型是Fiefdom，hasMany子模型是Fief（但稍后可以并将包括更多）。当导航到/fiefdoms/x时，我希望在fiefdom特定字段之后显示一系列子模型的数据表，每个数据表有一个关系

我的数据表在隔离状态下工作得很好（fief index），但我对如何将它们加载到不专用于单个数据表的页面中有点困惑。我正在使用的一些相关代码片段

FiefController.php（索引）

FiefdomController.php（显示）

fiefDataTable.php

<?php

namespace App\DataTables;

use App\Models\Fief;
use Form;
use Yajra\Datatables\Services\DataTable;

class FiefDataTable extends DataTable
{

    /**
     * @return \Illuminate\Http\JsonResponse
     */
    public function ajax()
    {
        return $this->datatables
            ->eloquent($this->query())
            ->addColumn('action', 'fiefs.datatables_actions')
            ->make(true);
    }

    /**
     * Get the query object to be processed by datatables.
     *
     * @return \Illuminate\Database\Query\Builder|\Illuminate\Database\Eloquent\Builder
     */
    public function query()
    {
        $fiefs = Fief::query();

        return $this->applyScopes($fiefs);
    }

    /**
     * Optional method if you want to use html builder.
     *
     * @return \Yajra\Datatables\Html\Builder
     */
    public function html()
    {
        return $this->builder()
            ->columns($this->getColumns())
            ->addAction(['width' => '10%'])
            ->ajax('')
            ->parameters([
                'dom' => 'Bfrtip',
                'scrollX' => false,
                'buttons' => [
                    'print',
                    'reset',
                    'reload',
                    [
                         'extend'  => 'collection',
                         'text'    => '<i class="fa fa-download"></i> Export',
                         'buttons' => [
                             'csv',
                             'excel',
                             'pdf',
                         ],
                    ],
                    'colvis'
                ]
            ]);
    }

    /**
     * Get columns.
     *
     * @return array
     */
    private function getColumns()
    {
        return [
            'name' => ['name' => 'name', 'data' => 'name'],
            'territory_id' => ['name' => 'territory_id', 'data' => 'territory_id'],
            'fiefdom_id' => ['name' => 'fiefdom_id', 'data' => 'fiefdom_id'],
            'fiefdom_type' => ['name' => 'fiefdom_type', 'data' => 'fiefdom_type'],
            'ruler_id' => ['name' => 'ruler_id', 'data' => 'ruler_id'],
            'ruler_type' => ['name' => 'ruler_type', 'data' => 'ruler_type'],
            'steward_id' => ['name' => 'steward_id', 'data' => 'steward_id'],
            'steward_type' => ['name' => 'steward_type', 'data' => 'steward_type']
        ];
    }

    /**
     * Get filename for export.

     */
    protected function filename()
    {
        return 'fiefs';
    }
}

/fiefs的索引数据表显示得很好，但它在/fiefdoms/x中不起作用。当然，问题是没有数据表信息被发送到视图（$datatable未定义）。我应该在控制器中构建并发送它，还是通过ajax加载它？html生成器的东西，也许？记住，我需要包含多个数据表，完成此任务最简单的方法是什么？我是走错了路，还是可以直接将dataTable信息发送到视图？

解决方案是使用相关dataTable中的html builder函数

X控制器

use App\DataTables\YDataTable;

...

    public function show($id, YDataTable $yDataTable)
    {
        $dataTable = $yDataTable
            ->html()
            ->ajax([
                'url' => route('y.index'),
                'type' => 'GET',
                'data' => 'function(d) { d.key = "value"; }',
            ]);
        return view('whatever', compact('dataTable'));
    }

大多数datatable内容都是通过html（）函数设置的，数据源是通过ajax（）函数定义的。你可以从那里过滤什么的

<?php

namespace App\DataTables;

use App\Models\Fief;
use Form;
use Yajra\Datatables\Services\DataTable;

class FiefDataTable extends DataTable
{

    /**
     * @return \Illuminate\Http\JsonResponse
     */
    public function ajax()
    {
        return $this->datatables
            ->eloquent($this->query())
            ->addColumn('action', 'fiefs.datatables_actions')
            ->make(true);
    }

    /**
     * Get the query object to be processed by datatables.
     *
     * @return \Illuminate\Database\Query\Builder|\Illuminate\Database\Eloquent\Builder
     */
    public function query()
    {
        $fiefs = Fief::query();

        return $this->applyScopes($fiefs);
    }

    /**
     * Optional method if you want to use html builder.
     *
     * @return \Yajra\Datatables\Html\Builder
     */
    public function html()
    {
        return $this->builder()
            ->columns($this->getColumns())
            ->addAction(['width' => '10%'])
            ->ajax('')
            ->parameters([
                'dom' => 'Bfrtip',
                'scrollX' => false,
                'buttons' => [
                    'print',
                    'reset',
                    'reload',
                    [
                         'extend'  => 'collection',
                         'text'    => '<i class="fa fa-download"></i> Export',

                    'colvis'
                ]
            ]);
