Question

我一直在努力工作并且工作得非常好，但现在我需要打电话给＃34; hasMany＆＃34;关系并将其显示在表格中这是我的控制者：

public function anyData()
{

   $posts = Test::with('cola')->select('tests.*');

  return \DataTables::eloquent($posts)

  ->make(true);}

它给我一个这样的数组（testanyData route）：

{
"draw": 0,
"recordsTotal": 1,
"recordsFiltered": 1,
"data": [
{
"id": "1",
"nombre": "Sigrid Mann",
"descripcion": "lPcA0",
"stock": "49",
"imagen": "s14gN",
"created_at": "2017-10-27 18:35:54",
"updated_at": "2017-10-27 18:35:54",
"cola": [
{
"test_id": "1",
"tipo": "1",
"precio": "1",
"created_at": null,
"updated_at": null
}
  ]
}
],
"queries": [
{
"query": "select count(*) as aggregate from (select '1' as `row_count` from `tests`) count_row_table",
"bindings": [],
"time": 0.6
},
{
"query": "select `tests`.* from `tests`",
"bindings": [],
"time": 0.46
},
{
"query": "select * from `precios` where `precios`.`test_id` in (?)",
"bindings": [
1
],
"time": 0.52
}
],
"input": []
}

这是我的js：

$(document).ready(function(){
                listar();
        });
        var listar = function (){
                var table = $('#productos').DataTable({
                        "processing": true,
                        "serverSide": true,
                        "ajax": "testanyData",
                        "columns":[
                                {data:'id'},
                                {data:'nombre'},
                                {data:'stock'},
                                {data: 'cola.precio'},
                                {defaultContent:
                                        "some buttons"
                                }
                        ],
                        "language": idioma_esp

                });


}

但是当我加载视图时，我会收到警告：

DataTables警告：table id = productos - 请求的未知参数＆＃39; cola.precio＆＃39;对于第0行，第3列。有关此内容的详细信息错误，请参阅http://datatables.net/tn/4

这是我的观点：

<div class="row-fluid margin-body">
                <table id="productos" class="table table-hover table-condensed " >
                        <thead>
                                <tr>
                                        <th >Id</th>
                                        <th>Producto</th>
                                        <th>Stock </th>
                                        <th>Precio</th>
                                        <th></th>
                                </tr>
                        </thead>
                </table>
        </div>

我想要显示＆＃34; precio＆＃34;在th标签＆＃34; Precio＆＃34;。

似乎你的可乐关系是hasMany，因为它返回响应中指示的数组。

"cola": [ { "test_id": "1", "tipo": "1", "precio": "1", "created_at": null, "updated_at": null } ]

在这方面，您还应该将数据作为数组访问。

{data: 'cola.0.precio', name: 'cola.precio'},

或者您可以使用dataTables.js库的render api并循环显示可乐的所有可能值并相应地进行渲染。

数据表（yajrabox）嵌套对象显示（laravel hasMany关系）
