Laravel删除不起作用

【中文标题】Laravel删除不起作用【英文标题】:Laravel Delete not working 【发布时间】:2018-10-18 21:51:05 【问题描述】:正如标题所示,我无法使 delete() 选项起作用。我在网上查了很多帖子,但没有正确的答案。 我正在使用带有 Homestead 的 Laravel 5.5(一周前安装,最新版本左右)。
让我给你一些代码,我真的希望有人能够帮助我。
这让我头疼,奥氮平快用完了。请告诉我我做错了什么,如果有什么遗漏,请告诉我!
我想以管理员身份删除一个页面,但我 Laravel 似乎没有授权我并给我这个错误:
protected function methodNotAllowed(array $others)
throw new MethodNotAllowedHttpException($others);
这是我的控制器:
<?php
namespace App\Http\Controllers\Admin;
use Auth;
use App\Page;
use App\Http\Requests\WorkWithPage;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
class PagesController extends Controller
public function __construct()
$this->middleware('admin');
$this->middleware('can:manageUsers,App\User');
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index()
if (Auth::user()->isAdmin())
$pages = Page::paginate(20);
else
$page = Auth::user()->pages()->paginate(5);
return view('admin.pages.index', ['pages' => $pages]);
/**
* Show the form for creating a new resource.
*
* @return \Illuminate\Http\Response
*/
public function create()
return view('admin.pages.create')->with(['model' => new Page()]);
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(WorkWithPage $request)
Auth::user()->pages()->save(new Page($request->only([
'title','url','content'])));
return redirect()->route('pages.index')->with('status', 'Pagina succesvol aangemaakt');
/**
* Show the form for editing the specified resource.
*
* @param \App\Page $page
* @return \Illuminate\Http\Response
*/
public function edit(Page $page)
if(Auth::user()->cant('update', $page))
return redirect()->route('pages.index')->with('status', 'Pagina succesvol aangepast');
return view('admin.pages.edit', ['model' => $page]);
/**
* Update the specified resource in storage.
*
* @param \Illuminate\Http\Request $request
* @param \App\Page $page
* @return \Illuminate\Http\Response
*/
public function update(WorkWithPage $request, Page $page)
if(Auth::user()->cant('update', $page))
return redirect()->route('pages.index')->with('status', 'Dat mag jij niet');
$page->fill($request->only([
'title','url','content'
]));
$page->save();
return redirect()->route('pages.index')->with('status', 'Pagina succesvol aangepast');
/**
* Remove the specified resource from storage.
*
* @param \App\Page $page
* @return \Illuminate\Http\Response
*/
public function destroy(Page $page)
if(Auth::user()->cant('delete', $page))
return redirect()->route('pages.index')->with('status', 'Hey knul! Pssst! Wegwezen!');
$page->id->delete();
return redirect()->route('pages.index')->with('status', 'Page has been deleted.');
这是我的索引页面(后端的管理索引中的索引:
@extends('layouts.app') @section('content')
<div class="container">
@if (session('status'))
<div class="alert alert-info">
session('status')
</div>
@endif
<a href=" route('pages.create')" class="btn btn-primary">Nieuwe pagina</a>
<br>
<br>
<table class="table">
<thead>
<tr>
<th>Naam</th>
<th>URL</th>
<th>Opties</th>
</tr>
</thead>
@foreach($pages as $page)
<tr>
<td>
<a href=" route('pages.edit', ['page' => $page->id]) "> $page->title </a>
</td>
<td> $page->url </td>
<td class="text-right">
<a href=" route('pages.destroy', ['page' => $page->id])" class="btn btn-danger delete-link" data-message="Are you sure you want to delete this page?"
data-form="delete-form">
Delete
</a>
</td>
</tr>
@endforeach
</table>
$pages->links()
</div>
<form id="delete-form" action="" methode="POST">
method_field('DELETE')
!! csrf_field() !!
</form>
@endsection
然后是路线:
<?php
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
Route::get('/', function ()
return view('welcome');
);
Auth::routes();
Route::get('/admin', function()
return view('admin.index');
)->middleware('admin');
Route::resource('/admin/pages', 'Admin\PagesController', ['except' => ['show']]);
Route::resource('/admin/blog', 'Admin\BlogController', ['except' => ['show']]);
Route::resource('/admin/users', 'Admin\UsersController', ['except' => ['create', 'store', '']]);
Route::get('/home', 'HomeController@index')->name('home');
然后是政策:
<?php
namespace App\Policies;
use App\User;
use App\Page;
use Illuminate\Auth\Access\HandlesAuthorization;
class PagePolicy
use HandlesAuthorization;
public function before($user, $ability)
if ($user->isAdmin())
return true;
/**
* Determine whether the user can update the page.
*
* @param \App\User $user
* @param \App\Page $page
* @return mixed
*/
public function update(User $user, Page $page)
return $user->id = $page->user_id;
/**
* Determine whether the user can delete the page.
*
* @param \App\User $user
* @param \App\Page $page
* @return mixed
*/
public function delete(User $user, Page $page)
return $user->id = $page->user_id;
最后是中间件:
<?php
namespace App\Http\Middleware;
use Closure;
use Auth;
class AccessAdmin
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
if(Auth::check() && Auth::user()->hasAnyRole(['Super Admin','Admin']))
return $next($request);
return redirect('login');
更新:已修复!
在我改变的视图中:
@foreach($model as $post)
<tr>
<td>
<a href=" route('blog.edit', ['post' => $post->id]) "> $post->title </a>
</td>
<td> $post->user()->first()->name </td>
<td> $post->slug </td>
<td class="text-right">
<a href=" route('blog.destroy', ['blog' => $post->id])" class="btn btn-danger delete-link" data-message="Are you sure you want to delete this page?"
data-form="delete-form">
Delete
</a>
</td>
</tr>
@endforeach
</table>
$model->links()
</div>
<form id="delete-form" action="#" methode="POST">
method_field('DELETE')
!! csrf_field() !!
</form>
收件人:
@foreach($pages as $page)
<tr>
<td>
<a href=" route('pages.edit', ['page' => $page->id]) "> $page->title </a>
</td>
<td> $page->url </td>
<td class="text-right">
<form action=" route('pages.destroy', ['page' => $page->id]) " method="POST" class="btn btn-danger delete-link" >
<input type="submit" value="delete"/>
method_field('DELETE')
!! csrf_field() !!
</form>
</td>
</tr>
@endforeach
</table>
$pages->links()
【问题讨论】:
删除路由在哪里?欺骗? ***.com/questions/31622818/… 这很有趣;我在网上看了一些教程,他们知道如何在没有的情况下做到这一点。我一直在搞乱路线,但没有结果。我都试图同时学习 PHP 作为 Laravel,所以无法真正理解这里的问题(在我解决这个问题后,我会更多地使用 PHP,然后是 Laravel) 想到的其他事情...发布到 GET 路线。相信日志,它会告诉你错误。 缺少路由似乎适用于编辑(和更新)。关于 POST for GET 部分:这在 tut 中有明确说明。所以我就这么做了 您已从 achor 调用删除。那会做GET
不是吗?您应该考虑使用表单和类似链接的提交按钮来达到预期的效果
【参考方案1】:
不知道从哪里开始...
首先,您收到的异常是因为您向 url 发送了错误的方法。 (我从来没有那样做)但可能你在期待 POST 时发送 GET(使用 DELETE 覆盖)。你有错误的命名“方法”,它应该是“方法”。
接下来...不确定这是否已经完成$page->id->delete();
...也许$page->delete()
。
作为建议-也许使用!can()
而不是cant()
会更好。没有区别,但cant()
在某些时候可能会让您感到困惑。
我很高兴看到有人使用->fill()
方法,但是在处理复选框时您可能会遇到一个小问题。检查这个:https://github.com/LaraModulus/admin-core/blob/master/src/traits/HelpersTrait.php
【讨论】:
感谢您的评论。我修复了“方法”类型(一半荷兰人,我觉得自己像个白痴)。我也把它当作 $page->delete();在我开始搞砸之前。还原后,实际上没有任何变化(仍在尝试用 noob 语言翻译您评论的第一部分)。以上是关于Laravel删除不起作用的主要内容,如果未能解决你的问题,请参考以下文章
