Route::controllers - Method [index] does not exist

I am running PHP 7.0.25 and Laravel Framework 5.5.25.

I would like to use the laravel datatables package and followed the quickstart guide and have exactly the same controller and view.

However, when running my application I get the following error:

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

Stacktrace:

I expect that this error is coming from my route configuration, which I changed to Route::resource instead, as mentioned in the quickstart guide, of the deprecated - since laravel 5.3 - Route::controllers:

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

Any suggestions how to write the route properly?

PS.: I already used composer dumpautoload, composer install & composer update and it does not change the error

UPDATE

My current Controller looks like the following:

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);
    }
}

My view:

@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>

回答1:

You need to generate a resource controller using artisan

php artisan make:controller DatatablesController --resource

The create controller will have the methods needed by your resource route

more info

Note: the 3th param(the array) is not valid

回答2:

In your routes.php, Laravel search a controller (in your case, DatatablesController) and a method to execute in this controller like DatatablesController@methodToExecute.
By default, Laravel try to execute the method index. Like @madalinivascu wrote, this controller needs to exists.
