Twig 日期 time_diff 翻译 [英] Twig date time_diff translation

问题描述

我正在使用 Twig 日期扩展来获取工作 time_diff.

i am using Twig Date extension to get working time_diff.

{{ photo.getCreationDate|time_diff }}

我想让它多语言.我已经阅读了文档，它说

I want to make it multilanguage. I have read the docs, it says

要获得可翻译的输出，请给出Symfony\Component\Translation\TranslatorInterface 作为构造函数争论.返回的字符串格式为 diff.ago.XXX 或diff.in.XXX 其中 XXX 可以是任何有效单位:秒、分钟、小时、日、月、年.

To get a translatable output, give a Symfony\Component\Translation\TranslatorInterface as constructor argument. The returned string is formatted as diff.ago.XXX or diff.in.XXX where XXX can be any valid unit: second, minute, hour, day, month, year.

我不知道该怎么做，但似乎对我不起作用.

Im not sure how to do it, but seems it doesnt work for me.

这就是我在控制器中尝试的方式.

Thats the way i tried in my controller.

$twig = new Twig_Environment(new TranslatorInterface());$twig->addExtension(new Twig_Extensions_Extension_Date());

$twig = new Twig_Environment(new TranslatorInterface()); $twig->addExtension(new Twig_Extensions_Extension_Date());

我遇到下一个错误

错误:无法实例化接口Symfony\Component\Translation\TranslatorInterface

Error: Cannot instantiate interface Symfony\Component\Translation\TranslatorInterface

Twig_Environment 构造函数正在等待 Twig_LoaderInterface 对象，而不是 TranslatorInterface.

Twig_Environment constructor is waiting for Twig_LoaderInterface object, not TranslatorInterface.

应该如何让我翻译 time_diff 输出?

How it should be done to allow me to translate the time_diff output?

谢谢

推荐答案

您阅读的是 Twig 文档，而不是 Symfony2 的文档，即使两者都是由 SensioLabs 制作的.

What you read is the Twig documentation, not the Symfony2's, even if both are made by SensioLabs.

如果您使用 Symfony 全栈框架，Symfony\Component\Translation\TranslatorInterface 已经定义为 Twig 扩展的构造函数参数.

If you use the Symfony full-stack framework, the Symfony\Component\Translation\TranslatorInterface is already defined as a constructor argument of your Twig extension.

要确保，请查看位于 \vendor\twig\extensions\lib\Twig\Extensions\Extension\date.php

你应该看到这样的:

*\vendor\twig\extensions\lib\Twig\Extensions\Extension\date.php*

<?php

/**
 * This file is part of Twig.
 *
 * (c) 2014 Fabien Potencier
 *
 * For the full copyright and license information, please view the LICENSE
 * file that was distributed with this source code.
 */
use Symfony\Component\Translation\TranslatorInterface;

/**
 * @author Robin van der Vleuten <[e-mail]>
 */
class Twig_Extensions_Extension_Date extends Twig_Extension
{
    public static $units = array(
        'y' => 'year',
        'm' => 'month',
        'd' => 'day',
        'h' => 'hour',
        'i' => 'minute',
        's' => 'second',
    );

    /**
     * @var TranslatorInterface
     */
    private $translator;

    /**
     * Constructor.
     *
     * @param TranslatorInterface $translator A TranslatorInterface instance.
     */
    public function __construct(TranslatorInterface $translator = null)
    {
        $this->translator = $translator;
    }

// etc.

如果这就是你所拥有的，那么你现在要做的就是翻译本身.

If this is is what you have on your side, then what you have to do now is the translation itself.

Symfony2 没有为此提供现成的翻译文件，具体取决于您的语言环境，您必须制作它(或找到已经完成此操作的人并可以与您分享)).

Symfony2 doesn't come with a ready-made-translated-file-depending-on-your-locale for this, you have to make it (or find someone that has already done this and is OK to share it with you).

首先，将此参数添加到 services.yml 中的 Twig 扩展:

First, add this argument to the Twig Extension in your services.yml :

*services.yml*

twig.extension.date:
    class: Twig_Extensions_Extension_Date
    arguments: ["@translator"] // careful of quotes
    tags:
        - { name: twig.extension }

然后，在 \app\Resources\translations 位置创建一个 date.fr.xliff".如果您在自己的 Bundle 中工作，请调整位置，即与 AppBundle 不同.当然，根据您正在寻找的语言，调整fr"(如de"、es"...).为什么.xliff"延期 ?当然，您可以创建一个.yml"文件.文件，例如.但是使用.xliff"允许您利用我接下来向您提出的建议.

Then, create a "date.fr.xliff" in the location \app\Resources\translations. Adapt the location if you're working in a Bundle of your own, i.e. different of AppBundle. Of course, depending on the language you are looking for, adapt the "fr" (like "de", "es"...). Why ".xliff" extension ? Of course, you could create an ".yml" file, for example. But using ".xliff" allow you to take advantage of what I suggest to you next.

然后，如果我继续使用法语翻译示例，请打开您的date.fr.wliff"文件并复制/粘贴由 KnpTimeBundle 提供的翻译.

Then, if I keep going with the french translation example, open your "date.fr.wliff" file and copy/paste the translation provided by the KnpTimeBundle.

如有必要，请不要忘记清除开发缓存.

Don't forget to clear the dev cache if you have to.

如果您正在寻找在 Twig 模板中进行的翻译，只需使用过滤器而不做任何更改(不要尝试添加第二个过滤器|trans"):

If you're looking for the translation to take place in a Twig template, just use the filter without changing anything (don't try to add a second filter "|trans") :

{{ user.createdAt|time_diff }}

当然，替换user.createdAt"根据您在那里的需要.

Of course, replace the "user.createdAt" by what you need there.

如果您愿意，只需在您的应用程序中实现 KnpTimeBundle 即可为您完成所有这些工作.否则，我想你可以复制/粘贴 KnpTimeBundle 提供的大量不同语言的翻译文件，只需注意替换它们的文件名time.fr.xliff"即可.来自date.fr.xliff"，Symfony2 包中的 Twig Extension 需要它.

If you want to, just implement the KnpTimeBundle in your application to do all of this for you. Otherwise, I guess it's OK for you to copy/paste the translation files provided by the KnpTimeBundle for a huge amount of different languages, just take care of replacing their filename "time.fr.xliff" by "date.fr.xliff", which is needed by the Twig Extension available in the Symfony2 pack.
