禁用特定模板的 Twig 编译缓存 [英] Disable Twig compilation cache for a particular template

问题描述

有没有办法禁用特定模板的 Twig 编译缓存?

Is there a way to disable the Twig compilation cache for a particular template?

我的电子邮件模板使用 Twig.当有人更新这些模板时，它们会被写入磁盘.虽然在生产中，我应该清除整个缓存，否则不会注意到更新.

I'm using Twig for my email templates. When someone updates these templates, they are written to disk. Although in production, I should clear the entire cache otherwise the updates aren't noticed.

这就是为什么我要禁用这些特定模板的 Twig 缓存.我不介意额外的处理能力，因为清除我的整个缓存会对性能造成更大的影响.

That's why I want to disable the Twig cache for these particular templates. I don't mind the extra processing power, as clearing my entire cache is a bigger performance hit.

推荐答案

我认为您的答案可能不是禁用特定模板的缓存，而是在模板更新后清除缓存.我没有测试下面的代码，但它似乎是合理的.稍微玩一下

I think your answer might be not in disabling cache for a specific template, but clearing the cache for a template after it's been updated. I haven't tested the code below, but it seems reasonable. Play around with it a bit

在您保存模板的操作/服务中(在保存模板后):

In your action/service that saves a template (after the template has been saved):

$fileCache = $this->container->get('twig')->getCacheFilename('AcmeDemoBundle:Default:index.html.twig');

if (is_file($fileCache)) {
    @unlink($fileCache);
}

有关更多信息，请查看如何在/vendor/twig/twig/lib/Twig/Environment.php (\Twig_Environment) -- 方法 loadTemplate() 中提交 twig 缓存文件.
