How do I get odd and even values in a Django for loop template?

问题

I have this code

{% for o in some_list %}

Now I want to do some stuff if I am on an even line. How can I do that?

回答1:

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

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

回答2:

In first level cycle:

{% cycle 'odd' 'even' %}

Reference:

• Documentation for cycle template tag

回答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>
