Laravel 5.5 尝试获取非 object 的属性 - 在 make:auth 命令之后

Question

我使用了make:auth命令进行身份验证。但是当我打开“/home”url 时，它给了我那个错误。我不知道那是什么，我该如何解决。

Full Error: Trying to get property of non-object (View: /home/vagrant/www/blog/resources/views/front/pages/single.blade.php)

（我使用 single.blade 来显示我的帖子）

路线：

Auth::routes();
Route::get('/home', 'HomeController@index')->name('home');
// also here is my single route
Route::get('/{slug}', 'BlogController@getSingle')->name('post_slug');

Single.blade.php

@extends('front.master')
@section('content')
    <div class="container">
        <div class="row">
            <div class="col-md-9">

                <div class="blog-post">
                    <h2 class="blog-post-title">{{$post->title}}</h2>
                    <p class="blog-post-meta">{{$post->created_at}} </p>
                    <hr/>
                    <div class="blog-main">
                        {{$post->body}}
                    </div>
                </div>

            </div>

        </div>
@endsection

BlogController - getSingle

public function getSingle($slug){
        $post = Post::where('slug', $slug)->first();
        return view('front.pages.single')->with('post', $post);
    }

Front.master blade 文件（简单 bootstrap 示例）

我哪里弄错了？

Answer 1

尝试在您的 Single.blade.php:

中使用它

@extends('front.master')
@section('content')
  @if(count($post) > 0)
    <div class="container">
        <div class="row">
            <div class="col-md-9">

                <div class="blog-post">
                    <h2 class="blog-post-title">{{$post->title}}</h2>
                    <p class="blog-post-meta">{{$post->created_at}} </p>
                    <hr/>
                    <div class="blog-main">
                        {{$post->body}}
                    </div>
                </div>

            </div>

        </div>
     </div>
   @else
     <h3>No post yet.</h3>
   @endif
@endsection

Answer 2

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

在路由文件中使用下面的内容

Route::get('/', 'HomeController@index')->name('home');
<a class="{{Request::is('/') ? "nav-link active" : "nav-link"}}" href="{!! route('home') !!}">Anasayfa</a>
