如何引用Django模板列表中的最后一个项目？ {{list.-1.key}} [英] How can reference the last item in a list in a Django template? {{ list.-1.key }}

问题描述

如果我在长度不明的上下文中有一个变量，例如;

list = [{'key'：'A'}，{'key'：' B'}，{'key'：'C'}]

如何获取最后一个对象？ {{list.0.key}} 适用于第一个，但 {{list.-1.key}} 给出;

无法解析余数：'-1.key'from'list.-1.key'

解决方案

感谢大家帮忙，这让我意识到我可以使用使用标签。

  {％with list | last as last％} 
 {{last.key}} 
 {％endwith％} 
  

if I have a variable in the context of unknown length, for example;
list=[{'key':'A'},{'key':'B'},{'key':'C'}]

How can I get the last object? {{ list.0.key }} works for the first, but {{ list.-1.key }} gives;
Could not parse the remainder: '-1.key' from 'list.-1.key'

解决方案

Thanks everyone for you help, it lead me to the realisation that I can use the with tag.

{% with list|last as last %}
    {{ last.key }}
{% endwith %}
