Question

Laravel 5.6.3 委托：1.9

我正在尝试为此播种机仅播种一排

<?php

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

class RoleSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
       $role =  Role::create([
            'name' => 'super-admin',
            'display_name' => 'Super Admin',
            'description' => 'This will be one permission, that can not be assigned or created.'
        ]);

        $permission = Permission::first()->where('name', 'super-admin')->first();
        $role->attachPermission($permission);
    }
}

模型

<?php

namespace App\models;

use Illuminate\Database\Eloquent\Model;
use Zizaco\Entrust\EntrustRole;

use App\models\Permission;
use App\User;

class Role extends EntrustRole
{
    public function permissions()
    {
        return $this->belongsToMany(Permission::class);
    }

    public function users()
    {
        return $this->belongsToMany(User::class);
    }
}

现在，当我尝试播种时，出现此错误。

更新

我在修修补补上尝试过

>>> $permission = App\models\Permission::first();
=> App\models\Permission {#2923
     id: 1,
     name: "super-admin",
     display_name: "Super Admin",
     description: "This will be one permission, that can not be assigned or created.",
     created_at: "2018-08-31 05:01:08",
     updated_at: "2018-08-31 05:01:08",
   }
>>> $role = App\models\Role::first();
=> App\models\Role {#2925
     id: 1,
     name: "super-admin",
     display_name: "Super Admin",
     description: "This will be one permission, that can not be assigned or modified.",
     created_at: "2018-08-31 05:01:10",
     updated_at: "2018-08-31 05:01:10",
   }
>>> $role->attachPermission($permission);
PHP Error:  Class 'App/Permission' not found in D:/work/www/myapp/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Concerns/HasRelationships.php on line 656
>>>

正确的做法是什么？

Answer 1

在https://github.com/Zizaco/entrust回购底部，它说

如果您的应用使用自定义名称空间，则需要告知委托您的许可和角色模型所在的位置，可以通过编辑 config/entrust.php
中的配置文件

因此，您必须将权限模型名称空间更改为App\models\Permission，默认名称空间设置为App\Permission

因此，编辑config/entrust.php文件并更改permission

'permission' => 'App\models\Permission'

和

'role' => 'App\models\Role'

播种时为角色分配权限-委托
