forms - Symfony2:如何将自定义错误消息转换为表单类型？

Question

我需要翻译我的表单类型中的错误消息。这是我的表单类型代码:

class ReferFriendType extends AbstractType {

public function buildForm(FormBuilder $builder, array $options)
{
    $defaultSubject = "This is a default referral subject.";
    $defaultMessage = "This is a default referral message.";

    $builder->add('email1', 'email',array(
        'required' => true,
        'label' => 'Email 1* :',
        'attr' => array('class' => 'large_text'),
    ));
    $builder->add('email2', 'email',array(
        'label' => 'Email 2 :',
        'required' => false,
        'attr' => array('class' => 'large_text'),
    ));
    $builder->add('email3', 'email',array(
        'label' => 'Email 3 :',
        'required' => false,
        'attr' => array('class' => 'large_text'),
    ));
    $builder->add('email4', 'email',array(
        'label' => 'Email 4 :',
        'required' => false,
        'attr' => array('class' => 'large_text'),
    ));
    $builder->add('email5', 'email',array(
        'label' => 'Email 5 :',
        'required' => false,
        'attr' => array('class' => 'large_text'),
    ));
    $builder->add('subject', 'text', array(
        'data' => $defaultSubject,
        'required' => true,
        'label' => 'Subject* :',
        'attr' => array('class' => 'large_text'),
    ));
    $builder->add('message', 'textarea', array(
        'data' => $defaultMessage,
        'required' => true,
        'label' => 'Message* :',
        'attr' => array('rows' => '5', 'cols' => '40'),
    ));

}

public function getDefaultOptions(array $options)
{
    $collectionConstraint = new Collection( array(
        'fields' => array(
            'email1' => array(
                new Email(),
                new NotBlank(array(
                    'message' => 'You must enter atleast one email address for a valid submission',
                )),
            ),
            'subject' => new NotBlank(),
            'message' => new NotBlank(),
        ),
        'allowExtraFields' => true,
        'allowMissingFields' => true,
    ));

    return array(
        'validation_constraint' => $collectionConstraint,
        'csrf_protection' => false,
    );
}

public function getName()
{
    return 'referFriend';
}

}

我想将getDefaultOptions()方法中的“您必须输入至少一个电子邮件地址以进行有效提交”翻译成法语。我已经在messages.fr.yml中添加了翻译。但是它没有得到翻译。任何想法如何做到这一点？

验证翻译将转到validators.LANG.yml文件，而不是messages.LANG.yml文件。
