动态内容上的Symfony翻译 [英] Symfony translations on dynamic content

问题描述

使用Symfony，我知道您可以创建翻译文件，在其中指定不同语言的文本等。这对于表单标签和整个应用程序中的其他静态文本非常有用。

With Symfony I'm aware that you can create translation files in which you specify the text for different languages etc. This works great for form labels, and other static text across an application.

我想知道的是如何通过动态内容实现国际化。例如，如果您有一个 Product 实体，该实体的 description 字段。管理员可以通过后端更改此文本。

What I'm wondering though is how you could achieve internationalisation with dynamic content. For example if you have a Product entity with a description field. The administrator can alter this text through the back-end.

那么您将如何实现动态文本的国际替代方案？

So how would you implement the international alternatives for dynamic text?

推荐答案

您需要创建两个必要的实体文件，第一个是EntityName，第二个是EntityNameTranslation。请看下面的例子。

You need to create two necessary entity files, first is EntityName, second is EntityNameTranslation. Please look at the example below.

类别实体

<?php

namespace BundleName\Entity;
use Doctrine\ORM\Mapping as ORM;
use Knp\DoctrineBehaviors\Model as ORMBehaviors;

/**
 * @ORM\Entity
 */
class Category
{
    use ORMBehaviors\Translatable\Translatable;

    /**
     * @ORM\Column(type="string", length=255)
     */
    protected $someFieldYouDoNotNeedToTranslate;

    // or do it with PropertyAccessor that ships with Symfony SE
    // if your methods don't take any required arguments
    public function __call($method, $arguments)
    {
        return \Symfony\Component\PropertyAccess\PropertyAccess::createPropertyAccessor()->getValue($this->translate(), $method);
    }
}

类别翻译实体

<?php

namespace BundleName\Entity;
use Doctrine\ORM\Mapping as ORM;
use Knp\DoctrineBehaviors\Model as ORMBehaviors;

/**
 * @ORM\Entity
 */
class CategoryTranslation
{
    use ORMBehaviors\Translatable\Translation;

    /**
     * @ORM\Column(type="string", length=255)
     */
    protected $name;

    /**
     * @ORM\Column(type="string", length=255)
     */
    protected $description;

    /**
     * @return string
     */
    public function getName()
    {
        return $this->name;
    }

    /**
     * @param  string
     * @return null
     */
    public function setName($name)
    {
        $this->name = $name;
    }

    /**
     * @return string
     */
    public function getDescription()
    {
        return $this->description;
    }

    /**
     * @param  string
     * @return null
     */
    public function setDescription($description)
    {
        $this->description = $description;
    }
}

设置和坚持

<?php

    $category = new Category;
    $category->translate('fr')->setName('Chaussures');
    $category->translate('en')->setName('Shoes');
    $em->persist($category);

    // In order to persist new translations, call mergeNewTranslations method, before flush
    $category->mergeNewTranslations();

    $category->translate('en')->getName();

    public function setDefaultOptions(OptionsResolverInterface $resolver)

    /**

     */
    public function getName()
    {
        return 'ngs_contentbundle_articles';
    }
}

获取

{% block content %}
    /*
       Because we use the magic function so we don't need specify the language so it will get the current local language
       //the magic function
       public function __call($method, $arguments)
    */
    <span>{{ category.getName }}</span>
    <span>{{ category.getDescription }}</span>
{% endblock %}
