如何在laravel 4.2中登录后重定向？

Route::get('login', 'AuthController@showLoginForm');
Route::post('login', 'AuthController@login');
Route::get('dashboard', ['before' => 'auth', 'uses' => 'DashboardController@index']);

php artisan make:controller AuthController

use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Redirect;

class AuthController extends BaseController
{
    public function showLoginForm()
    {
        return view('login');
    }

    public function login()
    {
        $credentials = [
            'email' => Input::get('email'),
            'password' => Input::get('password')
        ];

        if (Auth::attempt($credentials)) {
            return Redirect::intended('dashboard');
        } else {
            return Redirect::back()->withInput()->withErrors('Invalid credentials');
        }
    }
}

php artisan make:controller DashboardController

class DashboardController extends BaseController
{
    public function index()
    {
        return view('dashboard');
    }
}
