php - 从 laravel 中的空值创建默认对象时出错

问题描述

所以每次我尝试编辑某些东西时都会收到这个错误。我最好的猜测是我没有正确链接某些东西。或者它根本不起作用。

这是我收到错误时的 URL： http://sde2.test/ticket/%7Bid%7D 据我所知，当我尝试保存它时，它没有得到正确的 id。

无论如何，提前感谢您的回答！

这是我的票务控制器：

<?php

namespace App\Http\Controllers;

use App\Ticket;
use Illuminate\Http\Request;

use Illuminate\Support\Facades\DB;
use Redirect, Response;

class TicketController extends Controller
{
    public function setUpdate($ticketId, Request $request)
    {
        $ticket = Ticket::find($ticketId);

        $ticket->name = $request->name;
        $ticket->email = $request->email;
        $ticket->phonenr = $request->phonenr;
        $ticket->desc = $request->desc;
        $ticket->update = $request->update;


        $ticket ->save();

        return Redirect::to('ticket')->withSuccess('Het is gelukt, ticket is geupdate!');
    }

还有我的票模型：

class Ticket extends Model
{
    protected $fillable = [
        'name',
        'email',
        'phonenr',
        'desc',
        'update'
    ];

    protected $dates = [
        'created_at',
        'updated_at'
    ];
}

这是我的票证：

<div class="row d-flex justify-content-center">
    <div class="col-md-6">

                    </form>
                </td>
            </tr>
            </tbody>
        @endforeach
    </table>
</div>
</body>

这是我的 web.php

    Route::get('/ticket',  'TicketController@show');
    Route::post('/ticket/{id}', 'TicketController@setUpdate')->name('ticket.update');
    Route::post('/ticket/{id}', 'TicketController@setSolved')->name('ticket.approve');
    Route::delete('/ticket/{id}', 'TicketController@setDelete')->name('ticket.delete');

解决方案

如果我对您的理解正确，则由于 URL 错误，您无法编辑模型。解决方案是更改刀片中的一些代码：

<form action="ticket/{id}" method="post">

至

<form method="post" action="{{ route('ticket.update', ['id' => $ticket->id]) }}"> 还要检查approveandupdate方法，它们的 url 和 HTTP 方法是一样的，不认为它很好。
