Laravel/Sentinel 调用路由上未定义的方法

Question

我正在尝试按照这个很棒的教程构建一个通知系统： https://jplhomer.org/2017/01/building-realtime-chat-app-laravel-5-4-vuejs/

从数据库获取通知工作正常，但是当我尝试通过发布路由保持通知时，我的日志中出现以下错误：

我正在使用 Laravel 5.4、Sentinel、vue2 和 axios

[2017-03-24 15:00:58] local.ERROR: BadMethodCallException: Call to undefined method Illuminate\Database\Query\Builder::notification() in /Users/odp/www/laravel/vendor/laravel/framework/src/Illuminate/Database/Query/Builder.php:2445

在我的浏览器控制台中，我得到的只是：

Error: Request failed with status code 500

我的get和post路线如下：

// Notifications
Route::get('/notifications', function() {
    return App\Notification::with('user')->get();

});

Route::post('/notifications', function() {
    //$user = Auth::User(); //Original code from tutorial
    Sentinel::getUserRepository()->setModel('App\User');
    $user = Auth::getUser(); //Auth is now an alias for Sentinel

    $user->notification()->create([
    'notification' => request()->get('notification')
    ]);

    return ['status' => 'OK'];

});

app/User.php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Sentinel;

class User extends \Cartalyst\Sentinel\Users\EloquentUser
{
use Notifiable;

/**
 * The attributes that are mass assignable.
 *
 * @var array
 */
protected $fillable = [
    'first_name', 'email', 'password',
];

/**
 * The attributes that should be hidden for arrays.
 *
 * @var array
 */
protected $hidden = [
    'password', 'remember_token',
];

public function notifications()
{
    return $this->hasMany(Notification::class);
}
}

app/Notification.php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Sentinel; 

class Notification extends Model
{


    protected $fillable = [
        'notification',
    ];

    public function user()
    {
        return $this->belongsTo(User::class);
    }
}

我不知道这是否相关，但这是来自我的 app.js，我相信 axios.post 行会根据失败的路由创建 500 错误。

const app = new Vue({
el: '#app',

data: {

    notifications: []
},

methods: {

    addNotification(notification) {
        this.notifications.push(notification);

        axios.post('/notifications', notification).then(response => {

        })
    } 
},

created() {
    axios.get('/notifications').then(response => {
        //console.log(response);
        this.notifications = response.data;
    });
}
});

错误是它试图在 Illuminate\Database\Query\Builder 对象上调用 notification。

这让我相信 Auth::getUser() 实际上返回的是 Builder 对象，而不是您的实际用户模型。

我会尝试将 ->get() 添加到 $user = Auth::getUser()->get()。
