Symfony 2。如何允许表单忽略多余的字段？

在您的表单类型中：

        public function configureOptions(OptionsResolver $resolver)    {        $resolver->setDefaults(array( 'data_class' => 'AppBundleEntityYourEntity', 'translation_domain' => strtolower('entity_translation_domain'), 'allow_extra_fields' => true,        ));    }

该

allow_extra_fields
