How to map two entities in the one Symfony Form

The problem I am having now is related to entities and forms in Symfony2.

While creating the form that refers to one entity I can simply wire it by saying:

$user = new User();
$form->createForm(new UserType(), $user);
...
$manager->persist($user);
$manager->flush();

And that is working fine. But the problem raises when I have more complex form that is built based on other forms, e.g.

So, let's imagine I have a form called RegistrationType that contains two other forms called UserType wired to User entity and ProfileType wired to Profile entity.

Now, how can I handle that in the controller? I mean, I cannot do something like:

$user = new User();
$profile = new Profile();
$form->createForm(new RegisterType(), $user, $profile);
OR
$form->createForm(new RegisterType(), [$user, $profile]);
...
$manager->persist($user);
$manager->flush();

$profile->setUserId($user->getId());
$manager->persist($profile);
$manager->flush();

If I pass only $user, like so

$form->createForm(new RegisterType(), $user);

Symfony will complain that there are properties that are not mapped, of course I can set them to 'mapped' => false but then I have to set them later on manually.

What's the best way to handle this?

Thanks in advance!

Create UserType, ProfileType and RegistrationType forms. RegistrationType should add UserType and ProfileType as its children. Create Registration DTO and set it as data_class for RegistrationType. Then you can write something like

$user = new User();
$profile = new Profile();
$form->createForm(new RegistrationType(), 
           new Registration($user, $profile));
