现在我得到了这样的桌子

     public function light()
    {
        return $this->hasMany(Light::class, 'sx_ID','gy_sx_ID');
    }
    public function gylight()
   {
       return $this->hasMany(Gylight::class, 'light_gylight_number','gylight_number');
   }

我想将sx_Ename和sx_phone从我的light表显示到sx Detail列，如何加入表以获得值？

当我添加此消息时

但它以XHR形式获取值

构建3个这样的模型：

Gylight

public function index(Request $request)
{
    if($request->header('X-Requested-With') == 'XMLHttpRequest'){
        $column = array(
            'gylight_number',
            'gylight_status',
        );

        

        $filter = array();
        if($request->order) {
            $filter['orderByField'] = $column[$request->order[0]['column']];
            $filter['orderBy'] = $request->order[0]['dir'];
        }

        if($request->status ){
            $filter['status'] = $request->status;
        }

        if($request->search) {
            $filter['search'] = $request->search['value'];
            
        }

        $filter_row =  Gylight::select('*')
                        ->applyFilter($filter)
                        ->count();

        $gylight = Gylight::with('detail')
                            ->select('*')
                            ->offset($request->get('start'))
                            ->limit($request->get('length'))
                            ->applyFilter($filter)
                            ->get();

            $sub_array[] = '<button type="button" class="btn btn-primary radius choose_member" id="'.$gylight->id.'">'.
                           'Choose'.

}

public function gynumber()
{
    return $this->belongsTo(Guanyin::class, 'sx_ID','gy_sx_ID');
}

观音

     public function light()
    {
        return $this->hasMany(Light::class, 'sx_ID','gy_sx_ID');
    }
    public function gylight()
   {
       return $this->hasMany(Gylight::class, 'light_gylight_number','gylight_number');

public function index(Request $request)
{
    if($request->header('X-Requested-With') == 'XMLHttpRequest'){
        $column = array(
            'gylight_number',
            'gylight_status',

        $filter = array();
        if($request->order) {
            $filter['orderByField'] = $column[$request->order[0]['column']];
            $filter['orderBy'] = $request->order[0]['dir'];
        }

        if($request->status ){
            $filter['status'] = $request->status;
        }

        if($request->search) {
            $filter['search'] = $request->search['value'];
            
        }

        $filter_row =  Gylight::select('*')
                        ->applyFilter($filter)
                        ->count();

        $gylight = Gylight::with('detail')
                            ->select('*')
                            ->offset($request->get('start'))
                            ->limit($request->get('length'))
                            ->applyFilter($filter)
                            ->get();
             
        

        $data = [];
        foreach($gylight as $gylight){
            $sub_array = array();
            $sub_array[] = $gylight->id;
            $sub_array[] = $gylight->light_gylight_number;
            $sub_array[] = $gylight->status;
            $sub_array[] = $gylight->detail->sx_Ename;
            $sub_array[] = $gylight->gylight_receipt;
            $sub_array[] = $gylight->gylight_sDate;
            $sub_array[] = $gylight->gylight_eDate;
            $sub_array[] = '<button type="button" class="btn btn-primary radius choose_member" id="'.$gylight->id.'">'.
                           'Choose'.
                           '</button>';
            $data[] = $sub_array;
        }
        return response()->json([
            'draw' => $request->draw,
            'recordsTotal' => Gylight::count(),
            'recordsFiltered' => $filter_row,
            'data' => $data,
            'request' => $filter,
        ]);
    }

   return view('admin.guanyin.index');
}

public function gynumber()
{
    return $this->belongsTo(Guanyin::class, 'light_gylight_number','gylight_number');
}

public function gynumber()
{
    return $this->belongsTo(Guanyin::class, 'sx_ID','gy_sx_ID');
}

然后获取数据：

$gynumber = Guanyin::with(['light','gylight'])->orderBy('gylight_sDate', 'desc')->get();

添加筛选器并连接其他表。

祝你好运

你应该使用雄辩的

有一个到
。然后获得如下数据：
$sub_array[]=$gylight->light->sx_Ename阅读此处了解更多详细信息：@NgôMinh你能帮我看看我的模型吗？我已经更新了它，但我不确定这是否正确等10分钟，我会给你写我的答案。我尝试使用你编写的
hasOneThrough
函数，但看起来它不是wokring。我在这里得到一些错误消息，它是
消息：“试图获取非对象的属性'sx_Ename'”
使用
dd（$gylight->detail）
要查看数据，如果使用eloquent，则无需使用
leftJoin
<代码>$gylight=gylight:：with（'detail'）->“其他过滤器或排序…”在返回json到视图之前可以添加（$data）吗
