Question

我正在将Laravel与spatie / laravel-permission包一起使用，如本tutorial中所述。但是，当我尝试创建虚拟数据时，它返回以下错误 Spatie \ Permission \ Exceptions \ RoleDoesNotExist：没有名为Admin的角色。

下面是生成伪数据的类。

class DatabaseSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        // Ask for db migration refresh, default is no
        if ($this->command->confirm('Do you wish to refresh migration before seeding, it will clear all old data ?')) {
            // Call the php artisan migrate:refresh
            $this->command->call('migrate:refresh');
            $this->command->warn("Data cleared, starting from blank database.");
        }

        // Seed the default permissions
        Permission::firstOrCreate(['name' => 'Administer roles & permissions', 'guard_name' => 'isAdmin']);


        $this->command->info('Default Permissions added.');

        // Confirm roles needed
        if ($this->command->confirm('Create Roles for user, default is admin and user? [y|N]', true)) {

            // Ask for roles from input
            $input_roles = $this->command->ask('Enter roles in comma separate format.', 'Admin,User');

            // Explode roles
            $roles_array = explode(',', $input_roles);

            // add roles
            foreach($roles_array as $role) {
                $role = Role::firstOrCreate(['name' => trim($role), 'guard_name' => 'isAdmin']);

                if( $role->name == 'Admin' ) {
                    // assign all permissions
                    $role->syncPermissions(Permission::all());
                    $this->command->info('Admin granted all the permissions');
                } else {
                    // for others by default only read access
                    $role->syncPermissions(Permission::where('name', 'LIKE', 'view_%')->get());
                }

                // create one user for each role
                $this->createUser($role);
            }

            $this->command->info('Roles ' . $input_roles . ' added successfully');

        } else {
            Role::firstOrCreate(['name' => 'User']);
            $this->command->info('Added only default user role.');
        }

        // now lets seed some posts for demo
        $this->command->info('Some Posts data seeded.');
        $this->command->warn('All done :)');
    }

    /**
     * Create a user with given role
     *
     * @param $role
     */
    private function createUser($role)
    {
        $user = factory(User::class)->create();
        $user->assignRole($role->name);

        if( $role->name == 'Admin' ) {
            $this->command->info('Here is your admin details to login:');
            $this->command->warn($user->email);
            $this->command->warn('Password is "secret"');
        }
    }
}

有解决的主意吗？

Answer 1

您需要运行

php artisan cache:forget spatie.permission.cache

使用角色或权限之前

Answer 2

我通过更改config / auth.php文件中的警卫顺序来解决此错误：

这是默认设置

    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],
        'api' => [
            'driver' => 'jwt',
            'provider' => 'users',
        ],
    ],

这就是我现在拥有的

    'guards' => [
        'api' => [
            'driver' => 'jwt',
            'provider' => 'users',
        ],
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],
    ],

我发现，当我将默认防护设置更改为“ api” （默认设置为“ web” ）时，出现了此错误。

当您为角色播种而不更改顺序时，它会正确将guard_name设置为“ api” ，但是当它想将这些角色应用于用户时，可能会使用“ web” 后卫。

如果您使用的是默认值守卫，但仍然出现此错误，只需尝试在这样的角色播种器中设置guard_name字段

Role::create(['name' => 'admin', 'guard_name' => 'web']);

由Spatie / Laravel-permission引起的此问题还将模型类型存储在db中，并将许可权授予BackpackUser或User模型。

请参阅此链接以供参考：

https://github.com/Laravel-Backpack/PermissionManager/issues/193]

该解决方案刚刚于2019年底从烟熏炉中添加：

https://backpackforlaravel.com/docs/4.0/base-about#having-both-regular-users-and-admins

基本上，您需要添加中间件，或者在用户上添加is_admin列，或者使用tabacitu提供的中间件
