在laravel中获取500内部错误

Question

我是laravel的新手。我想从数据库中获取数据并将其放入数据表。这是我的html

<div class="tab-pane" id="th_days_client" >
                        <div class="panel panel-default">
                            <div class="panel-heading">
                                <h4 class="panel-title">
                                    <i class="material-icons">flag</i>
                                    {{ $title }}
                                </h4>
                                <span class="pull-right">
                                    <i class="fa fa-fw fa-chevron-up clickable"></i>
                                    <i class="fa fa-fw fa-times removepanel clickable"></i>
                                </span>
                            </div>
                            <div class="panel-body">
                                <div class="table-responsive">
                                    <table id="th_days_client_data" class="table table-bordered">
                                        <thead>
                                        <tr>
                                            <th>Name</th>
                                            <th>Email</th>
                                            <th>Mobile</th>
                                            <th>Actions</th>
                                        </tr>
                                        </thead>
                                        <tbody>
                                        </tbody>
                                    </table>
                                </div>
                            </div>
                        </div>
                    </div>

为此的jQuery是：

var th_days_client;
    $(document).ready(function () {
        th_days_client = $('#th_days_client_data').DataTable({
            "processing": true,
            "serverSide": true,
            "order": [],
            "columns":[
                {"data":"name"},
                {"data":"email"},
                {"data":"mobile"},
                {"data":"actions"}
            ],
            "ajax": "{{ url('client') }}" + ((typeof $('#th_days_client_data').attr('data-id') != "undefined") ? "/" + $('#id').val() + "/" + $('#th_days_client_data').attr('data-id') : "/th_days_client_data")
        });
    });

控制器的功能是：

public function th_days_client_data(Datatables $datatables)
{

   $clientObj = new Client;
    $client = $clientObj->get()
        ->map(function ($client) {
        return [
            'id' => $client->id,
            'name' => $client->first_name.' '.$client->last_name,
            'email' => $client->email,
            'mobile' => $client->mobile
        ];
    });

    return $datatables->collection($client)

        ->addColumn('actions', '@if(Sentinel::inRole(\'admin\'))
                                <a href="{{ url(\'client/\' . $id . \'/edit\' ) }}" title="{{ trans(\'table.edit\') }}">
                                        <i class="fa fa-fw fa-pencil text-warning "></i> </a>
                                @endif
                                <a href="{{ url(\'client/\' . $id . \'/show\' ) }}" title="{{ trans(\'table.details\') }}" >
                                        <i class="fa fa-fw fa-eye text-primary"></i> </a>
                                @if(Sentinel::inRole(\'admin\'))
                                <a href="javascript:void(0)" onclick="deleteClient({{$id}})"  title="{{ trans(\'table.delete\') }}">
                                        <i class="fa fa-fw fa-trash text-danger"></i> </a>
                                   @endif')

        ->removeColumn('id')
        ->rawColumns(['actions'])->make();
}

我的路线是

Route::group(['prefix' => 'client'], function () {
Route::get('data', 'Users\ClientsController@data');
Route::get('pending_client_data', 'Users\ClientsController@pending_client_data');
Route::get('th_days_client_data', 'Users\ClientsController@th_days_client_data');
Route::get('{client}/edit', 'Users\ClientsController@edit');
Route::post('{client}/update', 'Users\ClientsController@update');
Route::get('{client}/show', 'Users\ClientsController@show');
Route::get('{client}/delete', 'Users\ClientsController@delete');

}）;

运行此命令时，出现500内部错误。当我转到laravel.log文件时，错误是：

[2018-08-01 08:59:27] local.ERROR: Method [th_days_client_data] does not exist on [App\Http\Controllers\Users\ClientsController]. {"exception":"[object] (BadMethodCallException(code: 0): Method [th_days_client_data] does not exist on [App\\Http\\Controllers\\Users\\ClientsController]. at /var/www/webroot/ROOT/files/vendor/laravel/framework/src/Illuminate/Routing/Controller.php:68)

我该如何解决？
