【中文标题】为啥我的 laravel 集合返回 500 错误，即使不是在我使用 dd() 检查结果时？【英文标题】：Why is my laravel collection returning 500 error even it's not when I checked the results using dd()?为什么我的 laravel 集合返回 500 错误，即使不是在我使用 dd() 检查结果时？ 【发布时间】：2021-10-17 17:07:30 【问题描述】：我这里有一个 Yajra 数据表，它显示基于另一个数据表的记录。意思是第一个表的记录，当单击时，会在另一个内部数据表（#tbl-received-items）中显示该记录的记录。目前，我遇到一个错误：
DataTables warning: table id=tbl-received-items - Ajax error. For more information about this error, please see http://datatables.net/tn/7
当我在 chrome 中看到网络选项卡时，出现 500 错误并显示：
表示结果有问题。请帮我找出我的 createReceivedItemsCollection() 函数中的错误。
我可以确认我的$collection 正在返回正确的集合。请看截图。
这是我的路线：
Route::get('receiving-history', [ReceivingHistoryController::class, 'index'])->name('receiving-history.index');
Route::get('receiving-history/list', [ReceivingHistoryController::class, 'getReceivingHistory']);
Route::get('receiving-history/voucher_id', [ReceivingHistoryController::class, 'show'])->name('receiving-history.show');
Route::get('received-items/list', [ReceivingHistoryController::class, 'getReceivedItems']);
这是我的控制器：
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\
Product,
ReceiveItems
;
use DataTables;
class ReceivingHistoryController extends Controller
public function index()
return view('receiving-history.index');
public function show(Request $request, ReceiveItems $receive_items)
if ($request->ajax())
$data = $this->createReceivedItemsCollection($request);
return Datatables::of($data)->make(true);
return view('receiving-history.show', ['receive_items' => $receive_items]);
public function getReceivingHistory(Request $request)
if ($request->ajax())
$data = ReceiveItems::latest()->get();
return Datatables::of($data)->make(true);
public function getReceivedItems(Request $request)
if ($request->ajax())
$data = $this->createReceivedItemsCollection($request);
return Datatables::of($data)->toJson();
public function createReceivedItemsCollection(Request $request)
$received_items = ReceiveItems::where('voucher_id', '=', $request->voucher_id)->get();
foreach($received_items as $received_item)
$product_ids = $received_item->product_id;
$list = [];
foreach($product_ids as $product_item_no => $product_id)
$products = Product::where('id', '=', $product_id);
$voucher_cost = $products->value('cost');
$qty_addend = $received_item->qty_per_item;
$list[] = array(
'product_item_no' => $product_item_no + 1,
'product_id' => $product_id,
'product_name' => $products->value('name'),
'size' => $products->value('size'),
'qty_addend' => $qty_addend[$product_item_no],
'voucher_cost' => $voucher_cost,
'ext_cost' => number_format($voucher_cost * $qty_addend[$product_item_no], 2)
);
$list = (object)$list;
$collection = collect($list);
return $collection;
我的数据表 JS 文件：
$(document).ready(function ()
$.noConflict();
var voucherID = document.cookie;
// =datatable
let table = $('#tbl-received-items').DataTable(
processing: true,
language:
processing: '<div class="loader-container"><div class="loader"></div></div>'
,
ajax: "/received-items/list",

footerCallback: function(row, data, start, end, display)
var api = this.api(),
data;
var intVal = function(i)
return typeof i === 'string' ?
i.replace(/[\$,]/g, '') * 1 :
typeof i === 'number' ?
i : 0;
;
total = api
.column(5)
.data()
.reduce(function(a, b)
return intVal(a) + intVal(b);
, 0);
$('span#total').text(new Intl.NumberFormat('en-PH',
style: 'currency',
currency: 'PHP',
).format(total));
);
);
function getBaseUrl()
return window.location.protocol + "//" + window.location.host;
然后是我的 html 表格：
<table id="tbl-received-items" class="min-w-full tbl-responsive">
<thead class="bg-gray-50">
<tr>
<th
class="px-6 py-3 text-left text-xs font-medium text-gray-500 uppercase tracking-wider">
Product Item #
</th>
<th
class="px-6 py-3 text-left text-xs font-medium text-gray-500 uppercase tracking-wider">
Product Name
</th>
<th
class="px-6 py-3 text-left text-xs font-medium text-gray-500 uppercase tracking-wider">
Size

<th
class="px-6 py-3 text-left text-xs font-medium text-gray-500 uppercase tracking-wider">
Qty
</th>
<th
class="px-6 py-3 text-left text-xs font-medium text-gray-500 uppercase tracking-wider">
Voucher Cost

<th
class="px-6 py-3 text-left text-xs font-medium text-gray-500 uppercase tracking-wider">
Ext. Cost
</th>
</tr>
</thead>
<tbody class="bg-white">
</tbody>
</table>
非常感谢任何帮助。
【问题讨论】：
【参考方案1】：我设法通过在第一个数据表上添加一个 onclick 事件来解决这个问题，该数据表将 localstorage 设置为凭证 ID。另外，我将它设置为 POST 以传递数据。
$('#tbl-receiving-history').on('click', 'tr', function ()
$voucher_id = $(this).attr('data-voucher-id');
sessionStorage.clear(); //clear first before setting localstorage
localStorage.setItem("data-voucher-id", $voucher_id);
);
然后在第二张表上，我只取localstorage的值：
$(document).ready(function ()
$.noConflict();
$voucher_id = localStorage.getItem('data-voucher-id');
// =datatable
let table = $('#tbl-received-items').DataTable(
processing: true,
language:
processing: '<div class="loader-container"><div class="loader"></div></div>'
