laravel 5.2无法传递变量来查看

Question

我有一个非常简单的控制器和视图.但由于某种原因,我无法将变量传递给我的观点.请注意,echo $project->title路由器内部工作.

控制器:

<?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);
    }

}

视图:

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

但由于某种原因,我不断收到此错误:

Answer 1

发送到视图的数据需要是关联数组.请改用:

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

Answer 2

更换:

return view('home', $project);

同

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

要么

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