呼叫未定義的方法 App\Models\User::attachRole() 錯誤

Question

呼叫未定義的方法 App\Models\User::attachRole() 我是 Laravel 的絕對初學者 當我嘗試註冊時，我正在使用“laratrust”包，它給了我這個錯誤，我不知道為什麼

`<?php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use App\Providers\RouteServiceProvider;
use App\Models\User;
use Illuminate\Foundation\Auth\RegistersUsers;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;
use Laratrust\Traits\HasRolesAndPermissions;

class RegisterController extends Controller
{
    use RegistersUsers;
    use HasRolesAndPermissions;

    protected $redirectTo = RouteServiceProvider::HOME;

    public function __construct()
    {
        $this->middleware('guest');
    }

    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => ['required', 'string', 'max:255'],
            'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
            'password' => ['required', 'string', 'min:8', 'confirmed'],
        ]);
    }
    protected function create(array $data)
    {
        $user = User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => Hash::make($data['password']),
        ])/*->attachRole('user')*/;
        return $user->attachRole('admin');
    }
}

您的 User 模型中沒有任何 atachRole 方法。 所以看來您錯過了安裝部分的第4步。

在您的使用者類別中新增 Laratrust\Contracts\LaratrustUser 介面和 Laratrust\Traits\HasRolesAndPermissions 特徵（通常位於 App\Models\User 中）。

use Laratrust\Contracts\LaratrustUser;
use Laratrust\Traits\HasRolesAndPermissions;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable implements LaratrustUser // 
{
    use HasRolesAndPermissions;  // <- This will add some methods and property to your class ( attachRole included )

    // ...
}
