laravel - Laravel MethodNotAllowedHttpException on put 动作

问题描述

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，因为我发现了很多有关此问题的消息，但这并没有解决问题。

我的路线清单很好，centers.update 必须没问题，所以我不明白这个问题：

λ php artisan route:list

有人有想法吗？

解决方案

我认为

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

应该

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

$centresid 对吗？如果不是，则更$centres改为centres->idForm ( 'route'=> ['centres.update', $centres->id]) 中的内容，这可能是主要原因。
