laravel：表單模型綁定為空，因此出現錯誤

Question

這是我的家庭控制器：

<?php

namespace App\Http\Controllers;

use App\Http\Requests;
use Illuminate\Http\Request;

use App\Http\Models\Profile as Profile;
use Auth;

class HomeController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('auth');
    }

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $profile = Profile::where('user_id',Auth::user()->id)->first();
        return view('home.index')->with("profile", $profile);
    }
}

這是我的觀點（部分觀點）：

<img src="{{ $profile ?: url('images/'.$profile->logo) }}" alt="Profile-Image" class="img-circle" width="44">
{{ $profile->company_name ?: Auth::user()->username}}

這是我的個人資料表：

user_id | company_name | 商標

如您所見，我沒有user_id = 1的數據，因此$ profile值不是來自db，然后出現此錯誤：

Trying to get property of non-object
(View: /opt/lampp/htdocs/works/menu/resources/views/layout/header.blade.php)
(View: /opt/lampp/htdocs/works/menu/resources/views/layout/header.blade.php)
(View: /opt/lampp/htdocs/works/menu/resources/views/layout/header.blade.php)

我現在能做什么 ？

在您看來，嘗試一下：

<img src="{{ !$profile ?: url('images/'.$profile->logo) }}" alt="Profile-Image" class="img-circle" width="44">
{{ $profile->company_name ?: Auth::user()->username}}
