Laravel 5.2 kann Variable übergeben, um zu sehen

Question

Ich habe eine sehr einfache Steuerung und Ansicht. Aber aus irgendeinem Grund kann ich keine Variable an meine Sicht weitergeben. Beachten Sie, dass echo $project->title innerhalb des Routers funktioniert.

Controller:

<?php 

namespace App\Http\Controllers; 

use App\Http\Requests; 
use Illuminate\Http\Request; 
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() 
    { 
     $project = \App\Projects::find(1); 
     return view('home', $project); 
    } 

}

Ausblick:

 <div class="panel-body"> 
      You are logged in! 
      {{ $project->title }} 
     </div> 

Aber aus irgendeinem Grund, warum ich diesen Fehler erhalte:

Answer 1

Die Daten zur Ansicht geschickt muss ein a sein Assoziatives Array. Verwenden Sie stattdessen:

return view('home', ['project' => $project]); 

Answer 2

ersetzen:

return view('home', $project); 

mit

return view('home', compact($project)); 

oder

return view('home')->with('project', $project);
