Single Laravel Route for multiple controllers

Question

I am creating a project where i have multiple user types, eg. superadmin, admin, managers etc. Once the user is authenticated, the system checks the user type and sends him

You can do this with a Before Middleware that overrides the route action's namespace, uses and controller attributes:

use Closure;
use Illuminate\Http\Request;
use Illuminate\Contracts\Container\Container;
use App\Http\Middleware\AdminMiddleware;
use App\Http\Middleware\SuperAdminMiddleware;

class AdminRoutingMiddleware
{
    /**
     * @var Container
     */
    private $container;

    public function __construct(Container $container)
    {
        $this->container = $container;
    }

    private static $ROLES = [
        'admin' => [
            'namespace' => 'Admin',
            'middleware' => AdminMiddleware::class,
        ],
        'super' => [
            'namespace' => 'SuperAdmin',
            'middleware' => SuperAdminMiddleware::class,
        ]
    ];

    public function handle(Request $request, Closure $next)
    {
        $action = $request->route()->getAction();
        $role = static::$ROLES[$request->user()->role];

        $namespace = $action['namespace'] . '\\' . $role['namespace'];

        $action['uses'] = str_replace($action['namespace'], $namespace, $action['uses']);
        $action['controller'] = str_replace($action['namespace'], $namespace, $action['controller']);
        $action['namespace'] = $namespace;

        $request->route()->setAction($action);

        return $this->container->make($role['middleware'])->handle($request, $next);
    }
}

This way you have to register each route only once without the final namespace prefix:

Route::group(['middleware' => 'App\Http\Middleware\AdminRoutingMiddleware'], function () {
    Route::get('dashboard', 'dashboard@index');
    Route::get('users', 'manageUsers@index');
});

The middleware will convert 'dashboard@index' to 'Admin\dashboard@index' or 'SuperAdmin\dashboard@index' depending on current user's role attribute as well as apply the role specific middleware.
