django 1.5 - 如何在静态标签中使用变量 [英] django 1.5 - How to use variables inside static tag

问题描述

我正在将项目中的所有静态文件引用迁移到django 1.5引入的新的{％static％}标签，但是我有一个问题，在某些地方我使用变量来获取内容。有新的标签我不能，有没有办法解决这个问题？

I'm currently migrating all the static files references in my project to the new {% static %} tag that django 1.5 introduced, but I'm having a problem, in some places I use variables to get the content. With the new tag I can't, is there any way to solve this?

当前代码：

<img src="{{ STATIC_URL }}/assets/flags/{{ request.LANGUAGE_CODE }}.gif" alt="{% trans 'Language' %}" title="{% trans 'Language' %}" />

应该是什么（这不起作用）：

What it should be (this doesn't work):

<img src="{% static 'assets/flags/{{ request.LANGUAGE_CODE }}.gif' %}" alt="{% trans 'Language' %}" title="{% trans 'Language' %}" />

推荐答案

您应该可以连接字符串与 添加模板过滤器：

You should be able to concatenate strings with the add template filter:

{% with 'assets/flags/'|add:request.LANGUAGE_CODE|add:'.gif' as image_static %}
  {% static image_static %}
{% endwith %}

您尝试执行的操作不适用于 static 模板标签，因为它仅包含字符串或变量：

What you are trying to do doesn't work with the static template tag because it takes either a string or a variable only:

{% static "myapp/css/base.css" %}
{% static variable_with_path %}
{% static "myapp/css/base.css" as admin_base_css %}
{% static variable_with_path as varname %}
