Django模板循环。会员之前 [英] Django template for loop. Member before

问题描述

我想创建这样的循环：

{% for object in objects %}
    {% if object.before != object %}
         {{ object }} this is different
    {% else %}
        {{ object }} this is the same
{% endfor %}

根据 https://docs.djangoproject.com/en/dev/ref/templates/builtins/?from=olddocs#for I不能。真的没有简单的方法吗？或者我只需要使用计数器并检查对象[counter-1] ？

Based on https://docs.djangoproject.com/en/dev/ref/templates/builtins/?from=olddocs#for I can't. Is there really no simple way to do this? Or I just need to use counter and check for objects[counter-1]?

P.S。 .before 是理论，对象是简单的查询列表。我想在当前循环成员之前遇到的循环成员执行某些操作。

P.S. .before is theoretical and objects is simple query list. I want to take and do something with the loop member that encountered before current loop member.
