Set id attribute in Symfony Form to twig variable

Question

I want to add a twig variable to my table row id in a form.

{% for child in form %}               
    {{ form_widget(child, {'id':'asterisks-rating-loop.index' }) }} 
{% endfor %}

Currently it is not being parsed as a twig variable. Is there any way to set the id to 'asterisks-rating-'loop.index using this setup without the use of Javascript or jQuery?

I tried 'escaping' it with:

{{ form_widget(child, {'id':'asterisks-rating-{{loop.index}}' }) }}
{{ form_widget(child, {'id':'asterisks-rating-'{{loop.index}}'' }) }}

But obviously none of these solutions work.

The best practice should be:

to add a form collection instead of several forms if you can (eg. if your forms are not processed individually).
to add your dynamic id in the type's getName() method if your forms are processed individually, example:

BobType.php

<?php

namespace Fuz\AppBundle\Form;

use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;

class BobType extends AbstractType
{

    protected $suffix;

    public function __construct($suffix)
    {
        $this->suffix = $suffix;
    }


    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
           ->add('whatever', 'text')
        ;
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array (
                'data_class' => 'Fuz\AppBundle\Entity\BobData',
        ));
    }

    public function getName()
    {
        return 'BobType-' . $suffix;
    }

}

BobController.php

$formA = new BobType("hello"); // {{ formA.whatever.vars.id == BobType-hello-whatever }}
$formB = new BobType("world"); // {{ formB.whatever.vars.id == BobType-world-whatever }}
