Symfony2 embedded forms rendering in a twig template - php

Question

I'm new to Symfony and twig templates. The problem I have is that I can't figure it out how to render the embedded form's fields separately in a twig template. I tried to search for it but probably others used a bit different forms and those examples didn't work for me.
My forms:
class RegistrationType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('user', new UserType());
$builder->add(
'terms',
'checkbox',
array('property_path' => 'termsAccepted')
);
$builder->add('Register', 'submit');
}
public function getName()
{
return 'registration';
}
}
and
class UserType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('username', 'text');
$builder->add('name', 'text');
$builder->add('email', 'email');
$builder->add('password', 'repeated', array(
'first_name' => 'password',
'second_name' => 'confirm',
'type' => 'password',
'invalid_message' => 'Neteisingai pakartotas slaptažodis.',
));
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Keliones\MainBundle\Entity\User'
));
}
public function getName()
{
return 'user';
}
}
How the rendering field by field should look for that?

Basically Symfony and Form Framework creates Form object base on Type configuration classes. Form object has createView() method which is passed to view http://api.symfony.com/2.4/Symfony/Component/Form/FormView.html
In twig you can access embeded FormView object like that:
{# access embeded form #}
{{ form_row(form.user.username) }}
{{ form_row(form.user.email) }}
{{ form_row(form.user.password) }}
{# access main form field #}
{{ form_row(form.terms) }}
