在 Jinja 2 中使用变量作为字典键

Question

<div class = "col-lg-2">
<div class = "shadow card text-center">
{% for i in cart %} 
    {{i}} x {{req["{i}qty"]}}

有什么方法可以传递 {{req["{i}qty]}}

并使其在 jinja2 中表现得像 req[f'{i}qty']？

Answer 1

Have you tried something like this?

{% for i in cart %} 
{{i}} x {{req["{}qty".format(i)]}}
{% endfor %}
