129. Proteger rutas de acuerdo a los permisos

Hola , no me permite crear en cada modelo el metodo constructor y asociarlo al middleware , lo asigne en boostrap/app.php


<?php


use Illuminate\Foundation\Application;
use Illuminate\Foundation\Configuration\Exceptions;
use Illuminate\Foundation\Configuration\Middleware;
use Illuminate\Support\Facades\Route;


return Application::configure(basePath: dirname(__DIR__))
->withRouting(
web: __DIR__.'/../routes/web.php',
api: __DIR__.'/../routes/api.php',
commands: __DIR__.'/../routes/console.php',
health: '/up',
then: function (){
Route::middleware(['web', 'auth', 'role:admin'])
->prefix('admin')
->name('admin.')
->group(base_path('routes/admin.php'));
}
)
->withMiddleware(function (Middleware $middleware) {
$middleware->validateCsrfTokens(except: [ //evito que vaya a ser procesada por niubiz
'checkout/paid',
]);
$middleware->alias([
'verify.stock' => \App\Http\Middleware\VerifyStock::class,
'role' => \Spatie\Permission\Middleware\RoleMiddleware::class,
'permission' => \Spatie\Permission\Middleware\PermissionMiddleware::class,
'role_or_permission' => \Spatie\Permission\Middleware\RoleOrPermissionMiddleware::class,
]);
})
->withExceptions(function (Exceptions $exceptions) {
//
})->create();
