Symfony2 Assetic 动态图像包含在 Twig 中

我想使用 Twig 和 Assetic 加载文章的特定缩略图。这是不起作用的代码：

在配置和参数中：

thumbnail_dir="/Resources/public/images/article_thumbs"

twig:
    debug:             %kernel.debug%
    strict_variables: %kernel.debug%
    globals:
        thumbnail_dir: %thumbnail_dir%

在树枝文件中：

{% image '@MyMainBundle' ~ thumbnail_dir ~ '/' ~ id ~ '/' ~ article.thumbnailFile %}
    <img src="{{ asset_url }}"
         alt="{{ article.title }}" />
{% endimage %}

所以基本上我有图像存储在 /Resources/public/images/article_thumbs/{ID}/{FILE.ext}

我想要获取 Twig 中特定文章的这些内容。我怎样才能做到这一点？

编辑： 为什么我不把它们放在 web 文件夹中？

我想我曾经在某个时候考虑过使用 Assetic 过滤器，但我认为确实没有必要。

我暂时将它们存储在 web 文件夹中。

因此，如果我制作 thumbnail_dir="/images/article_thumbs" 并将其放入网络目录中，我只需说 {{ asset(thumbnail_dir ~ '/' ~ id ~ '/' ~ Article.thumbnailFile ) }} 在树枝中？

原文

I want to load a specific thumbnail for an article using Twig and Assetic. Here is the code that doesn't work:

in config and params:

thumbnail_dir="/Resources/public/images/article_thumbs"

twig:
    debug:             %kernel.debug%
    strict_variables: %kernel.debug%
    globals:
        thumbnail_dir: %thumbnail_dir%

In the twig file:

{% image '@MyMainBundle' ~ thumbnail_dir ~ '/' ~ id ~ '/' ~ article.thumbnailFile %}
    <img src="{{ asset_url }}"
         alt="{{ article.title }}" />
{% endimage %}

So basically I have images I'm storing in /Resources/public/images/article_thumbs/{ID}/{FILE.ext}

I want to get those for a specific article in Twig. How can I achieve that?

EDIT:
Why am I not putting them in the web folder?

I guess I had thought about using Assetic filters at some point, but I suppose there is really no need.

I'll just store them in the web folder for now.

So if I make thumbnail_dir="/images/article_thumbs" and put that in the web dir, Do I just say {{ asset( thumbnail_dir ~ '/' ~ id ~ '/' ~ article.thumbnailFile ) }} in twig?
