Laravel MethodNotAllowedHttpException on put 动作

Question

我从 laravel 开始并尝试在旧版本（5.2）上做一个教程。 所以我尝试使用最新版本的 laravel 进行翻译。

我在编辑表单时遇到此错误：

symfony\Component\HttpKernel\Exception\ MethodNotAllowedHttpException 无消息

我在 web.php 上的路线

<?php

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {
    return view('welcome');
});

Auth::routes();

Route::get('/home', 'HomeController@index')->name('home');

Route::resource('centres', 'CentresController');

我的控制器是 Centrescontroller.php

<?php

namespace App\Http\Controllers;
use App\Http\Requests;
use Illuminate\Http\Request;
use App\http\Controllers\Controller;
use App\centre;

class CentresController extends Controller
{



  public function index()
  {
      $centres = Centre::get();
     return view('centres.index', compact('centres'));
  }

  public function edit($id)
  {
     $centres = Centre::find($id);
    /// dd($centres);
    return view('centres.edit', compact('centres'));
  }

  public function update($id, Request $request)
  {
      return "Utilisateur modifié !";

  }
}

我的带有编辑表单的模板是 /views/centres/edit.balde.php ：

@extends('layouts.app')

@section('content')
<h1>Editer</h1>
{!! Form::open(['url' => route('centres.update', $centres), 'method' => 'PUT' ]) !!}

    {{ method_field('PUT') }}

    {!! Form::text('titre', 'titre',  $centres->titre) !!}

    {!! Form::text('slug', 'slug',  $centres->slug) !!}

    {!! Form::textarea('description', 'description',  $centres->descriptif) !!}

    {!!Form::submit("Envoyer")!!}


{!! Form::close() !!}

@endsection

我尝试在两个部分中添加 put，因为我发现了很多关于这个问题的消息，但它并没有解决问题。

我的路线列表很好，centers.update 肯定没问题，所以我不明白这个问题：

有人有想法吗？

Answer 1

我找到了解决方案，但我认为它不是很好。 如果我把它写在我的模板中，表格是好的，我没有错误。

<form method="post" action="{{ route('centres.update', $centres->id) }}">


{!!  method_field('PUT') !!}
        {{ csrf_field() }}

        {!! Form::text('titre', 'titre',  $centres->titre) !!}

        {!! Form::text('slug', 'slug',  $centres->slug) !!}

        {!! Form::textarea('description', 'description',  $centres->descriptif) !!}

        {!!Form::submit("Envoyer")!!}


</form>

        @endsection

但我认为这不是好的解决方案吗？

Answer 2

把它写在@csrf 的表格上。在这里你可以找到更多关于它的信息https://laravel.com/docs/5.7/csrf

Answer 3

我觉得

{!! Form::open(['url' => route('centres.update', $centres), 'method' => 'PUT' ]) !!}

应该是

 {{ Form::open(['method' => 'put',  'route'=> ['centres.update', $centres], 'class'=>'form']) }}

$centres 是 id 对吗？如果不是，则将 $centres 更改为 Form ( 'route'=> ['centres.update', $centres->id] ) 中的 centres->id 之类的东西，这可能是主要原因。
