Question

我有一个问题需要翻译＆＃34;在飞行中＆＃34;表单类中的一些元素。这很奇怪，因为翻译器完美地适用于每个表单的标签（在buildForm（）方法中），但不适用于私有表单。

根据剖析器，甚至在这些方法中都没有调用翻译器。

这里翻译者被调用并起作用：

public function buildForm(FormBuilderInterface $builder, array $options) {

    $this->options = $options;
    $builder
        ->add('title', TextType::class, array(
                'label' => $this->getTranslator()->trans('Title')
            )
        )

但是在同一个班级里，它并没有：

private function getMaterialList() {
    try {
        $arrResult = $this->em->getRepository('AppBundle:Material')->findAllOrderedByNameWp();
        foreach($arrResult as $material) {
            $material->setName($this->getTranslator()->trans($material->getName()));
        }
    } catch (NoResultException $e) {
        unset($e);
    } catch (Exception $ex) {
        $this->logger->info('Unable to list materials from booktype class ' . $ex->getMessage());
        throw new \Exception(
            $this->getTranslator()->trans('errorListingMaterials')
        );
    }

    return $arrResult;
}

班级（没有额外的方法）：

类BookType扩展了AbstractType {

private $translator;
private $em;
private $request;
private $logger;

private function getTranslator() {

    if(!isset($this->translator)) {
        $this->translator = new Translator($this->options['locale']);
    }

    return $this->translator;
}

/**
 * List the Materials
 * 
 * @return an array of materials
 * @throws \Exception
 */
private function getMaterialList() {
    try {
        $arrResult = $this->em->getRepository('AppBundle:Material')->findAllOrderedByNameWp();
        foreach($arrResult as $material) {
            $material->setName($this->getTranslator()->trans($material->getName()));
        }
    } catch (NoResultException $e) {
        unset($e);
    } catch (Exception $ex) {
        $this->logger->info('Unable to list materials from booktype class ' . $ex->getMessage());
        throw new \Exception(
            $this->getTranslator()->trans('errorListingMaterials')
        );
    }

    return $arrResult;
}

/**
 * Constructor
 * 
 * @param Doctrine $doctrine
 * @param RequestStack $requestStack is the request stacl
 */
public function __construct(Doctrine $doctrine, RequestStack $requestStack, $logger) {
    $this->em = $doctrine->getManager();
    $this->request = $requestStack;
    $this->logger = $logger;        
}

public function buildForm(FormBuilderInterface $builder, array $options) {

    $this->options = $options;
    $builder
        ->add('title', TextType::class, array(
                'label' => $this->getTranslator()->trans('Title')

        ->add('year', TextType::class, array(

        )

                'choices' => $this->getFormatList()
            )
        )
        ->add('format', EntityType::class, array(
                'class' => 'AppBundle:Material',
                'label' => $this->getTranslator()->trans('Material'),
                'choices' => $this->getMaterialList()

            )
        )
        ->add('author', EntityType::class, array(
                'class' => 'AppBundle:Author',
                'label' => $this->getTranslator()->trans('Author.plural'),
                'choices' => $this->getAuthorList(),
                'multiple' => true
            )
        )
        ->add('kind', EntityType::class, array(
                'class' => 'AppBundle:Kind',
                'label' => $this->getTranslator()->trans('Kind.plural'),
                'choices' => $this->getKindList(),

            )
        )
        ->add('isbn', TextType::class, array(

        ->add('submit', SubmitType::class, array(
            'label' => $this->getTranslator()->trans('Save')

}

public function configureOptions(OptionsResolver $resolver) {
    $resolver->setDefaults(array(
            'data_class' => 'AppBundle\Entity\Book',
            'locale' => 'en', // the default locale
        )
    );
}

}

Answer 1

在浏览翻译器组件的代码之后，我不明白为什么这不起作用。

最后，这就是我所做的：

从3.0.2升级到3.1.3
删除了表单类
在我的表单类（声明为服务）中注入转换器组件

site.type.book： class：AppBundle \ Form \ BookType 标签： - {name：form.type} 参数：['@ doctrine'，'@ request_stack'，'@ logger'，'@ transnslator']

Symfony 3.0 FormType：翻译器不能在buildForm（）之外的其他方法中工作
