Question

我正在运行PHP 7.0.25和Laravel Framework 5.5.25。

我想使用laravel datatables package并跟随quickstart guide并且具有完全相同的controller和view。

但是，在运行我的应用程序时，我收到以下错误：

BadMethodCallException thrown with message "Method [index] does not exist on [App\Http\Controllers\DatatablesController]."

我希望这个错误来自我的路由配置，我已将其更改为Route::resource，如quickstart guide中所述，已弃用 - 因为laravel 5.3 - Route::controllers：

Route::resource('datatables', 'DatatablesController', [
    'anyData'  => 'datatables.data',
    'getIndex' => 'datatables',
]);

有关如何正确编写路线的任何建议吗？

PS：我已经使用过composer dumpautoload，composer install＆amp; composer update并且它不会更改错误

更新

我当前的控制器如下所示：

namespace App\Http\Controllers;

use App\Http\Requests;
use App\User;
use Yajra\Datatables\Datatables;

class DatatablesController extends Controller
{
    /**
     * Displays datatables front end view
     *
     * @return \Illuminate\View\View
     */
    public function getIndex()
    {
        return view('datatables.index');
    }

    /**
     * Process datatables ajax request.
     *
     * @return \Illuminate\Http\JsonResponse
     */
    public function anyData()
    {
        return Datatables::of(User::query())->make(true);
    }
}

我的观点：

@extends('layouts.master')

@section('content')
    <table class="table table-bordered" id="users-table">
        <thead>
            <tr>
                <th>Id</th>
                <th>Name</th>
                <th>Email</th>
                <th>Created At</th>
                <th>Updated At</th>
            </tr>
        </thead>
    </table>
@stop

@push('scripts')
<script>
$(function() {
    $('#users-table').DataTable({
        processing: true,
        serverSide: true,
        ajax: '{!! route('datatables.data') !!}',
        columns: [
            { data: 'id', name: 'id' },
            { data: 'name', name: 'name' },
            { data: 'email', name: 'email' },
            { data: 'created_at', name: 'created_at' },
            { data: 'updated_at', name: 'updated_at' }
        ]
    });
});
</script>

Answer 1

您需要使用artisan生成资源控制器

&amp;

创建控制器将具有资源路径所需的方法

注意：第3个参数（数组）无效

Answer 2

在routes.php中，Laravel搜索控制器（在您的情况下为DatatablesController）以及在此控制器中执行的方法，如DatatablesController@methodToExecute。
默认情况下，Laravel尝试执行方法index。就像@madalinivascu所写，这个控制器需要存在。

Route :: controllers - [App \ Http \ Controllers
