我有这段代码

现在我想做一些事情，如果我在一个偶数线上。我怎么能这样做？

Answer 1

https://docs.djangoproject.com/en/dev/ref/templates/builtins/#divisibleby

来自here：

{% if forloop.counter|divisibleby:2 %}even{% else %}odd{% endif %}

Answer 2

在第一级循环中：

{% cycle 'odd' 'even' %}

Answer 3

<div class="row">
{% for post in posts %}
      {% cycle 'odd' 'even' %}
      {% if cycle == 'odd' %}
        <div class="col-md-6">Odd posts</div>
      {% else %}
        <div class="col-md-6">Even posts</div>
      {% endif %}
    {% endfor %}
</div>

OR

<div class="row">
{% for post in posts %}
   {% if forloop.counter|divisibleby:2 %}
        <div class="col-md-6">Even posts</div>
      {% else %}
        <div class="col-md-6">Odd posts</div>
      {% endif %}
    {% endfor %}
</div>

Answer 4

<div class="row">
{% for post in posts %}
   {% if loop.index is divisibleby 2 %}
        <div class="col-md-6">Even posts</div>
      {% else %}
        <div class="col-md-6">Odd posts</div>
      {% endif %}
    {% endfor %}
</div>
