在 jinja 中设置变量 [英] Set variable in jinja

问题描述

我想知道如何在 jinja 中使用另一个变量设置变量.我会解释一下，我有一个子菜单，我想显示哪个链接处于活动状态.我试过这个:

I would like to know how can I set a variable with another variable in jinja. I will explain, I have got a submenu and I would like show which link is active. I tried this:

{% set active_link = {{recordtype}} -%}

其中 recordtype 是为我的模板提供的变量.

where recordtype is a variable given for my template.

推荐答案

{{ }} 告诉模板打印值，这在表达式中不起作用就像你正在尝试做的那样.相反，使用 {% set %} 模板标签，然后像在普通 python 代码中一样分配值.

{{ }} tells the template to print the value, this won't work in expressions like you're trying to do. Instead, use the {% set %} template tag and then assign the value the same way you would in normal python code.

{% set testing = 'it worked' %}
{% set another = testing %}
{{ another }}

结果:

it worked
