你好亲爱的，当用户需要删除或编辑帖子时，我遇到了问题，拉拉维尔显示错误"您无法编辑帖子..." 我在Laravel中使用模型和控制器，并使用用户"auth"系统ID进行访问帖子以进行删除或编辑，现在查看我的作品：
索引视图
@extends('layouts.app')
@section('content')
@auth
<h6 class="alert alert-dark">Dear Guest {{ Auth::user()->name }} for send a post <a class="btn btn-success" href="{{ route('ads.create') }}">Click</a> Here</h6>
@endauth
@guest
<div class="alert alert-primary">for send a post you can <a class="btn btn-success" href="{{ route('register') }}">Register</a></div>
@endguest
@if(count($adses) > 0)
<div class="row">
@foreach($adses as $ads)
<div class="col-xl-3 col-lg-3 col-md-6 col-sm-12">
<div class="card mb-4">
<img class="card-img-top img-fluid" src="/storage/cover_images/{{$ads->cover_image}}" alt="Card image cap">
<div class="card-body">
<h6 class="card-title"><a href="/ads/{{ $ads->id }}">{{ $ads->title }}</a></h6>
@if(!Auth::guest())
@if(Auth::user()->id == $ads->user_id)
<div class="row">
{!!Form::open(['action' => ['AdsController@destroy', $ads->id], 'method' => 'POST',]) !!}
{{Form::hidden('_method', 'DELETE')}}
{{Form::submit('Delete', ['class' => 'btn btn-danger'])}}
{!!Form::close() !!}
<a href="/ads/{{ $ads->id }}/edit" class="btn btn-primary mr-4">Edit</a>
</div>
@endif
@endif
</div>
</div>
</div>
@endforeach
{{ $adses->links() }}
@else
<p class="alert alert-warning" role="alert">any post !</p>
</div>
@endif

路由
Auth::routes();
Route::get('/home', 'HomeController@index')->name('home');
Route::resource('/', 'AdsController');
Route::resource('ads', 'AdsController');
现在，发送帖子并登录系统后，用户无法删除或编辑她的帖子。
谢谢
auth()->user()->id !== $ads->user_id .
有这条线。如果用户在创建帖子时没有登录，您将有user_id==空。签入数据库比user_id？
我解决了我的问题
if(auth()->user()->id !== $ads->user_id)
由于您使用的是 ！==，请确保您的user_id是整数
