Twig 扩展将在新的 Twig_Environment 中可用 [英] Twig extension to be available in new Twig_Environment

问题描述

我正在使用 Symfony 2/Twig.我有一个 Twig 扩展，除其他外，它会根据用户偏好重载日期过滤器以输出自定义日期格式.

I'm using Symfony 2 / Twig. I have a Twig extension which, among other things, overloads the date filter to output custom date formats based on user preference.

app/config/services.yml:

app/config/services.yml:

twig.extension.static:
    class: %twig_static_extension%  # set elsewhere
    tags:
        - { name: twig.extension }

我需要初始化一个新的 Twig_Environment 以呈现数据库中的模板:

I'm needing to initialize a new Twig_Environment in order to render templates from the database:

控制器:

$env = new \Twig_Environment(new \Twig_Loader_String());

但我发现这个新环境不会自动包含扩展.

But I am finding that this new environment does not automatically include the extension.

当然，我可以像这样加载它:

Naturally, I can load it like so:

$env->addExtension(new FQCN\To\StaticExtension());

我可以做些什么来使扩展可用于所有可能使用的 Twig 环境?

Is there something I can do to make the extension available to all Twig environments that might be used?

推荐答案

您可以创建一个 Compiler Pass 并将其注入您的 bundle，请访问 TwigEnvironmentPass 来自 TwigBundle
