Datatable.js - Laravel：JSON 列未过滤（可排序）

Question

我在 Mysql 数据库上使用 laravel 和包：yajra/laravel-datatables-oracle。我还使用 mcamara/laravel-localization 包来管理网站的不同语言。

下面雄辩的代码显示了一个 datatables.js 表：数据正确并且搜索引擎工作。但是，我无法对我的列应用订单。事实上，数据表允许您按升序/降序过滤列，但它不起作用。

我的字段中的数据：free_videos.title 和categories.title 作为类别，采用 JSON 格式（{"en": "My title", "fr": "Mon titre"}。

我已经在各个方向上尝试过filterColumn，但是当我单击相关列的标题时，我无法设法按升序或降序排列我的列：显示指示显示顺序更改的箭头并更改状态，但数据没有被过滤。

Laravel 代码：

public function active(Request $request)
    {
        $query = FreeVideo::query()->leftJoin('categories', 'free_videos.category_id', '=', 'categories.id')->select('free_videos.id', 'free_videos.title', 'categories.id as category_id', 'categories.title as category');

        return DataTables::eloquent($query)
            ->addColumn('freeVideoTitle', function($row){
                return $row->title; //Json table default lang : "fr" provided ("mcamara/laravel-localization")
            })
            ->editColumn('freeVideoCategory', function($row)
            {
                $category = json_decode($row->category, true);
                return isset($category['fr']) ? $category['fr'] : '';
            })
            ->editColumn('languages', function($row){
                return $row->getTranslations('title');
            })
            ->addColumn('actions', function($row) use ($request){
                $actions['edit'] = ['status' => 1, 'route' => route('backend.freeVideos.edit', $row->id)];
                $actions['destroy'] = ['status' => 1, 'route' => route('backend.freeVideos.destroy', $row->id)];
                return $actions;
            })
            ->make(true);
    }

Javascript代码：

table.DataTable({
            language: {url: '/assets/common/js/locales/datatable/fr.json'},
            dom:
                "<'row'" +
                "<'col-sm-6 d-flex align-items-center justify-conten-start'l>" +
                "<'col-sm-6 d-flex align-items-center justify-content-end'f>" +
                ">" +

                "<'table-responsive'tr>" +

                "<'row'" +
                "<'col-sm-12 col-md-5 d-flex align-items-center justify-content-center justify-content-md-start'i>" +
                "<'col-sm-12 col-md-7 d-flex align-items-center justify-content-center justify-content-md-end'p>" +
                ">",
            responsive: true,
            searchDelay: 500,
            processing: true,
            serverSide: true,
            pageLength: 50,
            ajax: ajaxProcessing,
            columns: [
                {
                    data: 'freeVideoTitle',
                    name: 'free_videos.title'
                },
                {
                    data: 'freeVideoCategory',
                    name: 'categories.title'
                },
                {
                    data: 'languages',
                    name: 'langs'
                },
                {
                    data: 'actions',
                    responsivePriority: -1
                },
            ],
            order: [[0, 'desc']], ...

已修复！

1. $query =>categories.title->fr 作为类别
2. JS => 名称：'free_videos.title->fr' 和名称：'categories.title->fr'

public function active(Request $request)
    {
        $query = FreeVideo::query()->leftJoin('categories', 'free_videos.category_id', '=', 'categories.id')->select('free_videos.id', 'free_videos.title', 'categories.id as category_id', 'categories.title->fr as category');

        return DataTables::eloquent($query)
            ->addColumn('freeVideoTitle', function($row){
                return $row->title;
            })
            ->addColumn('freeVideoCategory', function($row){
                return $row->category;
            })
            ->editColumn('languages', function($row){
                return $row->getTranslations('title');
            })
            ->addColumn('actions', function($row) use ($request){
                $actions['edit'] = ['status' => 1, 'route' => route('backend.freeVideos.edit', $row->id)];
                $actions['destroy'] = ['status' => 1, 'route' => route('backend.freeVideos.destroy', $row->id)];
                return $actions;
            })
            ->make(true);
    }

columns: [
                {
                    data: 'freeVideoTitle',
                    name: 'free_videos.title->fr'
                },
                {
                    data: 'freeVideoCategory',
                    name: 'categories.title->fr'
                },
                {
                    data: 'languages',
                    name: 'langs'
                },
                {
                    data: 'actions',
                    responsivePriority: -1
                },
            ],
