How to Define the Validation Groups to Use

If your object takes advantage of :doc:`validation groups </validation/groups>`, you'll need to specify which validation group(s) your form should use:

$form = $this->createFormBuilder($users, array(
    'validation_groups' => array('registration'),
))->add(...);

    The ``configureOptions()`` method was introduced in Symfony 2.7. Previously,
    the method was called ``setDefaultOptions()``.

If you're creating :ref:`form classes <form-creating-form-classes>` (a good practice), then you'll need to add the following to the configureOptions() method:

use Symfony\Component\OptionsResolver\OptionsResolver;

public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'validation_groups' => array('registration'),
    ));
}

In both of these cases, only the registration validation group will be used to validate the underlying object.
