问题描述
我们正在使用 Symfony2 构建一个新站点,Assetic 在资源管理方面看起来非常有前途,特别是在自动组合和处理所有 js/css 文件方面.
We are building a new site using Symfony2, and Assetic looks very promising for resource management, in particular for combining and processing all js/css files together automatically.
我们将拥有一些在网站范围内使用的资源,以及一些特定于特定页面的资源.我们还将对模板使用三层继承方法.
We wil have some resources that are used site wide, and some that are specific to particular pages. We will also be using a three tiered inherited approach to templates.
有没有办法将这两个概念结合起来,即在继承的模板中自动添加额外的资源,以便它们都作为单个资源输出?
Is there a way to combine the two concepts, i.e. to automatically add additional resources in inherited templates so that they are all output as a single resource?
推荐答案
很遗憾,你不能:(
您不能覆盖资产标签来添加更多资产.但是,您可以执行以下操作:
You can't override the assetic tags to add more assets. You can however do the following:
{% block stylesheets %}
{% stylesheets 'your_assets_here' %}
<link rel="stylesheet" href="{{ asset_url }}" />
{% endstylesheets %}
{% endblock %}
然后,当你扩展模板时:
Then, when you extend the template:
{% block stylesheets %}
{% stylesheets 'your_old_assets_here' 'your_new_assets_here' %}
<link rel="stylesheet" href="{{ asset_url }}" />
{% endstylesheets %}
{% endblock %}
在被覆盖的块中,你可以使用 parent()
来包含父块,但是你会有两个链接:你不能将旧的资产标签与新的标签结合起来.
In the overridden block, you can use parent()
to include the parent block, but you would have 2 links then: you can't combine the old assetic tag with the new one.
但是,您可以创建一个 twig 宏,将 {% stylesheets %} 资产标签与您的旧资产一起输出,并作为输入包含新资产位置.
You could however make a twig macro that would output the {% stylesheets %} assetic tag with your old assets, and as input it would contain new asset locations.
