如何在laraadmin中将表分配给新模块

Question

当我尝试将字段或记录手动添加到表中时，我从该ajax函数获得内部服务器错误响应
我是laraadmin的新手，所以我不太了解文件结构 索引视图中的代码：

<script>
    $(function () {
        $("#example1").DataTable({
            processing: true,
            serverSide: true,
            ajax: "{{ url(config('laraadmin.adminRoute') . '/event_rule_car_dt_ajax') }}",
            language: {
                lengthMenu: "_MENU_",
                search: "_INPUT_",
                searchPlaceholder: "Search"
            },
            @if($show_actions)
            columnDefs: [ { orderable: false, targets: [-1] }],
            @endif
        });
        $("#event_rule_car-add-form").validate({

        });
    });
</script>

以及控制器中的功能：

        public function dtajax()
        {
            $values = DB::table('event_rule_cars')->select($this->listing_cols)->whereNull('deleted_at');
            $out = Datatables::of($values)->make();
            $data = $out->getData();

            $fields_popup = ModuleFields::getModuleFields('Event_rule_cars');

            for($i=0; $i < count($data->data); $i++) {
                for ($j=0; $j < count($this->listing_cols); $j++) { 
                    $col = $this->listing_cols[$j];
                    if($fields_popup[$col] != null && starts_with($fields_popup[$col]->popup_vals, "@")) {
                        $data->data[$i][$j] = ModuleFields::getFieldValue($fields_popup[$col], $data->data[$i][$j]);
                    }
                    if($col == $this->view_col) {
                        $data->data[$i][$j] = '<a href="'.url(config('laraadmin.adminRoute') . '/event_rule_cars/'.$data->data[$i][0]).'">'.$data->data[$i][$j].'</a>';
                    }
                    // else if($col == "author") {
                    //    $data->data[$i][$j];
                    // }
                }

                if($this->show_action) {
                    $output = '';
                    if(Module::hasAccess("Event_rule_cars", "edit")) {
                        $output .= '<a href="'.url(config('laraadmin.adminRoute') . '/event_rule_cars/'.$data->data[$i][0].'/edit').'" class="btn btn-warning btn-xs" style="display:inline;padding:2px 5px 3px 5px;"><i class="fa fa-edit"></i></a>';
                    }

                    if(Module::hasAccess("Event_rule_cars", "delete")) {
                        $output .= Form::open(['route' => [config('laraadmin.adminRoute') . '.event_rule_cars.destroy', $data->data[$i][0]], 'method' => 'delete', 'style'=>'display:inline']);
                        $output .= ' <button class="btn btn-danger btn-xs" type="submit"><i class="fa fa-times"></i></button>';
                        $output .= Form::close();
                    }
                    $data->data[$i][] = (string)$output;
                }
            }
            $out->setData($data);
            return $out;
        }
