Laravel非对象

Question

我创建了一个简单的Laravel项目。在博客视图中，我具有页面索引（这里是最近5个博客的首页），编辑，显示和创建。现在，如果我从数据库中创建新博客（编辑/删除和显示/读取），则一切正常。但是我无法从站点创建新博客。看到问题了吗？

BlogControllor

/**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('blog.create');
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $this->validate($request, [
            'naslov'=>'Required',
            'slug'=>'Required|alpha_dash|min:5|max:255|unique:blogs,slug',
            'opis'=>'Required',
            'tekst'=>'Required',
            'upload_slike' => 'sometimes|image'
        ]);

        $blog = new Blog;
        $blog->naslov = $request->naslov;
        $blog->slug = $request->slug;
        $blog->opis = $request->opis;
        $blog->tekst = $request->tekst;

        //Sacuvaj novu sliku za blog post
        if ($request->hasFile('upload_slike')) {
            $image = $request->file('upload_slike');
            $filename = time() . '.' . $image->getClientOriginalExtension();
            $location = public_path('slike/' . $filename);
            Image::make($image)->resize(800, 400)->save($location);

            $blog->image = $filename;
        }

        $blog->save();
        return redirect('blog');
    }

路线

Route::resource('blog', 'BlogController');

索引页面上的按钮，用于创建新博客

<a href="{{ route('blog.create') }}" class="btn btn-success" style="margin-bottom: 25px;">Dodaj novu vest</a>

这个错误

图像中的错误表明在打开要删除的表单标签时发生了错误。检查您截取的屏幕截图中的第5行。

您是否在创建屏幕上包括了删除功能；也许在扩展视图layouts.bez-sidebar中？如果是这样的话，那可能就是为什么$blog->id导致trying to get property of non object错误的原因。
