Drupal 8 redirect user to own user edit page (for use in menu links)

AccountEditRedirectController.php

<?php

namespace Drupal\yourmodule\Controller;

use Drupal\Core\Controller\ControllerBase;

use Symfony\Component\HttpFoundation\RedirectResponse;

/**
 * A controller that redirects to the current user's edit account page.
 */
class AccountEditRedirectController extends ControllerBase {

  /**
   * Redirect to
   */
  public function redirect_to_account_edit() {
    global $base_url;

    $path = \Drupal\Core\Url::fromRoute('entity.user.edit_form', ['user' => \Drupal::currentUser()->id()])->toString();

    $response = new RedirectResponse($base_url . $path);
    $response->send();
  }

}

hnip_menu.routing.yml

yourmodule.account_edit_redirect:
  path: '/user/me/edit'
  defaults:
    _controller: '\Drupal\yourmodule\Controller\AccountEditRedirectController::redirect_to_account_edit'
  requirements:
    _role: 'authenticated'

If you're redirecting to routes, you can utilize the $this->redirect() method. Then you don't work with URLs and don't need to trreat the base_url.

public function redirect_to_account_edit() {
    $route_name = 'entity.user.edit_form';
    $route_parameters = [
      'user' => \Drupal::currentUser()->id(),
    ];

    return $this->redirect($route_name, $route_parameters);
}

This works! ⬆️

I had totally forgotten about this gist! Thanks for commenting with your updates :)
