尝试将id变量从'accounts'表传递给app.blade，其中包含未定义的变量错误

Question

我正在尝试将帐户表中的id变量传递到app.blade视图，以便为每个用户指定自定义URL。我试图将它存储在$ account中，但我显然没有做正确的事情。

错误消息：未定义的变量：account（查看：/home/vagrant/www/upsapp/resources/views/layouts/app.blade.php）（查看：/ home / vagrant / www / upsapp / resources / views /布局/ app.blade.php）

app.blade

<a class="navbar-brand" href=" {{ url('/account/'.$account->id).'/' }}">
   {{ $account->accountname}}
</a>

原始AccountController

<?php

namespace App\Http\Controllers;

use App\Account;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
use Illuminate\Support\Facades\Auth;

class AccountController extends Controller
{
    public function __construct()
    {
    $this->middleware('auth');
    }



public function index()
    {
    $result = Auth::user()->account()->get();
    if(!$result->isEmpty()){
        return view('account.dashboard',['account'=>$result,'image'=>Auth::user()]);
    }
    else{
        return view('account.dashboard',['account'=>false,'image'=>Auth::user()]);
    }
}

更新了AccountController

public function index()
{          
$result = Auth::user()->account()->get();
    if(!$result->isEmpty()){
        return view(layouts.app,['account'=>$result,'image'=>Auth::user()]);
    }
    else{
        return view(layouts.app,['account'=>false,'image'=>Auth::user()]);
    }
}

Account.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Account extends Model
{
protected $table = 'accounts';

protected $fillable = ['id', 'accountname',  'address1', 'address2', 'city', 'state', 'zip', 'accountalpha', 'accountnotes'];

public function account()
    {
    return $this->hasMany('App\User');
    }
}

路线

Route::get('/', function () {
return redirect('/login');
});

Auth::routes();

Route::resource('account','AccountController');

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

'帐户'表

Schema::create('accounts', function (Blueprint $table) {
        $table->increments('id')->unsigned();
        $table->string('accountname');
        $table->string('accountalpha')->nullable();
        $table->string('address1');
        $table->string('address2');
        $table->string('city');
        $table->string('state');
        $table->integer('zip');
        $table->string('accountnotes')->nullable();
        $table->timestamps();
    });

'用户'表

Schema::create('users', function (Blueprint $table) {
        $table->increments('id');
        $table->string('firstname');
        $table->string('lastname');            
        $table->string('email')->unique();
        $table->string('phonenumber');
        $table->string('password');
        $table->rememberToken();
        $table->timestamps();
        $table->integer('account_id');

        $table->foreign('account_id')->references('id')->on('accounts')->onDelete('cascade');
