我已经克隆了市场仓库并进行了适当的配置。当我使用时，php artisan db:seed我收到此错误

david@david-Lenovo-G50-30:~/projects/marketplacekit$ php artisan db:seed
Seeding: UsersTableSeeder
Seeding: RolesAndPermissionsSeeder

Spatie\Permission\Exceptions\PermissionAlreadyExists  : A `edit listing` permission already exists for guard `web`.

我使用json_encode如下方法在我的数据库的一列中保存一个数组，它可以工作：

    $service->description = $request->service_description;
    $service->image = json_encode($url);
    $service->duration = $request->service_delivery_time;

当我获取数据时，我得到一个字符串。我正在使用$service = Service::findOrFail($id);. 我可以按照下面的方法解码单个列并将其传递给视图。

    $service = Service::findOrFail($id);
    $images = json_decode($service->image);
    return view('services.show',['service'=>$service , 'images'=>$images]);

我要问的是，我可以在一个查询中解码图像吗？
