Redirect to "/" route in symfony

Question

I'm trying to redirect to the "/" route (same page) after a form submission:

/**
 * @Route("/")
 */

My approach:

return $this->redirectToRoute('/');

Gives me the following error:

Unable to generate a URL for the named route "/" as such route does not exist.

Answer 1

you have to name the route, like:

/**
* @Route("/", name="homepage")
*/

and then:

return $this->redirectToRoute('homepage');
