Laravel 中的数据表不起作用

Question

我正在尝试在 Laravel 中实现 DataTables，但它不起作用。表：

<table class="table table-striped" id="Clientes">
        <thead>
          <tr>
            <th>ID</th>
            <th>Nombre</th>
            <th>Domicilio</th>
          </tr>
        </thead>
        <tbody>

        </tbody>
</table>

脚本：

  $(document).ready(function() {
    $('#Clientes').DataTable( {
        "processing": true,
        "serverSide": true,
        "ajax": '{{ route('getClientes') }}',
        "columns": [
          {"data": 'id', "name": 'id'},
          {"data": 'nombre', "name": 'nombre'},
          {"data": 'domicilio', "name": 'domicilio'}
        ]
    } );
} );

还有路线：

Route::get('/api/clientes', [
        'as'    => 'getClientes',
        'uses'  => function(){
        $clientes = Cliente::select(['id','nombre','domicilio'])->get();
        return Datatables::of($clientes)->make();}
    ]);

表格显示错误： DataTables 警告：表 id=Clientes - Ajax 错误。有关此错误的更多信息，请参阅http://datatables.net/tn/7

但我无法解决问题。谁能帮帮我？

更新

错误是： message": "找不到类 'Yajra\Datatables\Facades\DataTables'", "异常": "Symfony\Component\Debug\Exception\FatalThrowableError",

Answer 1

最后不要使用get()。

代替

$clientes = Cliente::select(['id','nombre','domicilio'])->get();

使用

$clientes = Cliente::select(['id','nombre','domicilio']);

数据表服务器端 查看

                                <table  class="table table-striped display nowrap" id="brand">
                                    <thead class=" text-primary">
                                    <th>
                                        ID
                                    </th>

                                    <th>
