如何使用Laravel 5.4显示来自数据表的数据？

Question

I'm stuck with datatables and the plugin yajrabox for Laravel 5.4. The goal is to load with ajax and the plugin the data from the users tables in my database, but it just shows me this error :

DataTables warning: table id=listingUsers - Requested unknown parameter '0' for row 0, column 0. 

I can't find out where it's coming from and i'm not sure I wrote the code right..

Here is my code.

Controller :

 public function index() {
    $users = User::latest()->count();

    return view('admin.users.index', compact('users'));
}

 public function ajaxListing() {
    $users = User::select(['id', 'username', 'email']);
        return Datatables::of($users)->make(true);
}

Routes :

Route::resource('users', 'Admin\UsersController');
Route::any('user-data', 'Admin\UsersController@ajaxListing')->name('datatables.data');

View : `

<table class="table table-bordered table-responsive" id="listingUsers">
    <thead>
        <th>ID</th>
        <th>Nom</th>
        <th>Email</th>
    </thead>

    <tbody></tbody>
</table>

@push('scripts')
<script>
    $(document).ready(function () {
        $('#listingUsers').DataTable({
            processing: true,
            serverSide: true,
            ajax: '{!! route('datatables.data') !!}',
            columns: [
                {data: 0, name: 'id'},
                {data: 1, name: 'name'},
                {data: 2, name: 'email'}
            ]
        });
    });

</script>
@endpush`

WHen i'm searching the error in the console and the network the data comes right but just doesn't show in the table.

Can someone tell me what t'im doing wrong and how to fix it ?

Answer 1

In data , you need to specify the column name, like that:

columns: [
    {data: 'id', name: 'id'},
    {data: 'username', name: 'username'},
    {data: 'email, name: 'email'}
]
