资产中的树枝串联 [英] Twig concatenation in assets

问题描述

这很好用:

   {% image '@TestBundle/Resources/pic2/image.jpg' %} 
       <img src="{{ asset_url }}" alt="Example" />
   {% endimage %}

但我需要通过显示上传图像的名称而不是 image.jpg 来使其更具动态性.我需要以某种方式将资产与 {{ entity.picture }}

but I need to make it more dynamic by displaying the name of uploaded image instead of image.jpg. I need somehow to concatenate the asset with {{ entity.picture }}

有没有什么方法可以在 twig 中做到这一点而不会出错?

Is there any way to do this in twig without getting an error of course?

{% image '@TestBundle/Resources/pic2/' . {{ entity.picture }} %}  

推荐答案

你可以试试这个:

// config.yml add a global variable (Or just assign the path from the controller)
twig:
    globals:
        imagepath: "your/path/to/thepictures/"

我不认为这在树枝中有效，因为此图像用于 assets优化:

I don't this this works in twig since this image is used for assets optimization:

{% image {{ imagepath ~ entity.picture }} %}  

所以替代方案可以是:

<img src="{{ imagepath ~ entity.picture }}">
