Laravel 5 属性 [userType] 在此集合实例上不存在

Question

当我尝试设置登录条件时，我不断收到属性 [userType] 不存在错误下面是我的控制器代码。我也尝试制作 Auth 控制器，但我一直收到同样的错误。

<?php

namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;
use App\Providers\RouteServiceProvider;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use App\User;

class LoginController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles authenticating users for the application and
    | redirecting them to your home screen. The controller uses a trait
    | to conveniently provide its functionality to your applications.
    |
    */

    use AuthenticatesUsers;

    /**
     * Where to redirect users after login.
     *
     * @var string
     */
    protected $redirectTo = '/dashboard';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }

    protected function redirectTo()
{
    $user = User:all();
    if($user->userType == 'admin')
    {
        return 'dashboard';
    }
    else
    {
        return 'verify first';
    }
}
}

这是我的模型代码

<?php

namespace App;

use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;

class User extends Authenticatable
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *  protected $table = 'users';
    *public $primaryKey ='id';
     * @var array
     */
  
    protected $fillable = [
        'name', 'email', 'password','userType',
    ];

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

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

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

   
}

无论如何，我该如何解决这个问题？请告诉我在登录中创建重定向的正确方法，因为我只想创建一个具有管理员、用户和访客模式的登录。

Answer 1

很明显的错误

 protected function redirectTo()
{
    $user = User:all();
    if($user->userType == 'admin')
    {
        return 'dashboard';
    }
    else
    {
      
        return 'verify first';
    }
}

在 redirectTo 方法中您正在访问 $user = User:all(); 而不是一条记录。它可能是 Auth::user() 或 User::find($id)

$user = User:all();

全部 return 多条记录所以你不能直接访问 userType

您可以使用 authenticated method

而不是 redirectTo

protected function authenticated(Request $request, $user)
{
   if($user->userType == 'admin')
        {
             return redirect()->route("dashboard");
        }
        else
        {
           auth()->logout();
            
        }
}
