Feature request: enable custom user profile templates

[truckee]

It may be possible to enable custom user profile templates with the simple modification to Configuration.php as in the following excerpt:

->children()
    ->arrayNode('profile')
        ->addDefaultsIfNotSet()
        ->children()
            ->arrayNode('form')
            ->addDefaultsIfNotSet()
                ->children()
                    ->scalarNode('type')->defaultValue(null)->end()
                    ->scalarNode('name')->defaultValue('fos_user_profile_form')->end()
                    ->arrayNode('validation_groups')
                        ->prototype('scalar')->end()
                        ->defaultValue(array('Profile', 'Default'))
                    ->end()
                ->end()
            ->end()
            ->scalarNode('template')->defaultValue(null)->end()
         ->end()
    ->end()
->end()

Custom templates are possible with this modification and extending FOSUserBundle to allow the use of a custom ProfileController like the following:

class ProfileController extends BaseController
{

    /**
     * Edit the user
     */
    public function editAction(Request $request)
    {
        $user = $this->container->get('security.context')->getToken()->getUser();
        if (!is_object($user) || !$user instanceof UserInterface) {
            throw new AccessDeniedException('This user does not have access to this section.');
        }

        $discriminator = $this->container->get('pugx_user.manager.user_discriminator');
        $users = $this->container->getParameter('pugx_user_discriminator_users');
        $class = $discriminator->getClass($user);

        foreach ($users as $userType) {
            if ($userType['entity']['class'] == $class) {
                $templateString = $userType['profile']['template'];
                if (false === strpos($templateString, $this->container->getParameter('fos_user.template.engine'))) {
                    $template = 'FOSUserBundle:Profile:edit.html.';
                } else {
                    $l = strrpos($templateString, ".");
                    $template = substr($templateString, 0, $l + 1);
                }
            }
        }

        /** @var $dispatcher \Symfony\Component\EventDispatcher\EventDispatcherInterface */
        $dispatcher = $this->container->get('event_dispatcher');

        $event = new GetResponseUserEvent($user, $request);
        $dispatcher->dispatch(FOSUserEvents::PROFILE_EDIT_INITIALIZE, $event);

        if (null !== $event->getResponse()) {
            return $event->getResponse();
        }

        /** @var $formFactory \FOS\UserBundle\Form\Factory\FactoryInterface */
        $formFactory = $this->container->get('fos_user.profile.form.factory');

        $form = $formFactory->createForm();
        $form->setData($user);

        if ('POST' === $request->getMethod()) {
            $form->bind($request);

            if ($form->isValid()) {
                /** @var $userManager \FOS\UserBundle\Model\UserManagerInterface */
                $userManager = $this->container->get('fos_user.user_manager');

                $event = new FormEvent($form, $request);
                $dispatcher->dispatch(FOSUserEvents::PROFILE_EDIT_SUCCESS, $event);

                $userManager->updateUser($user);

                if (null === $response = $event->getResponse()) {
                    $url = $this->container->get('router')->generate('fos_user_profile_show');
                    $response = new RedirectResponse($url);
                }

                $dispatcher->dispatch(FOSUserEvents::PROFILE_EDIT_COMPLETED, new FilterUserResponseEvent($user, $request, $response));

                return $response;
            }
        }

        return $this->container->get('templating')->renderResponse(
                        $template . $this->container->getParameter('fos_user.template.engine'), array('form' => $form->createView())
        );
    }

This has all been at the limit of my skill set, so if it's out of place please let me know. But it was fun figuring it out.

Edit: I suspect there is much more to this request than originally thought. Ignore the above if it is deemed dumb.
