Laravel 5.2：委托：調用未定義的方法attachPermission

Question

我嘗試附加權限（如果不存在），並且在運行db seed之后出現錯誤-

<?php

use Illuminate\Database\Seeder;
use App\Role;
use App\Permission;
use App\User;

class AttachRolesAndPermissionsToUsers extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $admin = Role::where('name', 'admin')->first();
        $moderator = Role::where('name', 'moderator')->first();

        $createPost = Permission::where('name', 'create-post')->first();
        $editUser = Permission::where('name', 'edit-user')->first();


        // attach role
        $adminUser = User::where('email', 'a@gmail.com')->first();
        if(!$adminUser->hasRole('admin')) {
            $adminUser->attachRole($admin);
        }

        $moderatorUser = User::where('email', 'b@gmail.com')->first();
        if(!$moderatorUser->hasRole('moderator')) {
            $moderatorUser->attachRole($moderator);
        }

        // attach Permission
        if(!$adminUser->can(['create-post', 'edit-user'])) {
            $adminUser->attachPermissions([$createPost, $editUser]);
        }

        if(!$moderatorUser->can('create-post')) {
            $moderatorUser->attachPermission($createPost);
        }
    }
}

[BadMethodCallException]調用未定義的方法Illuminate \\ Database \\ Query \\ Builder :: attachPermission（）

Answer 1

更改為

$adminUser->perms()->sync([$createPost->id, $editUser->id]);

讓我們看看情況如何。

Answer 2

這是錯誤的實現，權限需要與角色而不是用戶一起附加。

$admin->attachPermissions([$createPost, $editUser]);
$moderator->attachPermission($createPost);

其中$admin和$moderator是角色對象。
