Modulus/Modulo equivalent operator/function in django templates?

Question

I'm just learning django's templating system and trying to do something relatively trivial:

<h2>State</h2>
<ul class="states">
{% for state in states %}
   <li class="state_elements" ><a href="/{{ state.name }}/"> {{ state.name }}</a></li>
   {% if forloop.counter \% 3 == 0 %}
   <br style="clear: both"/>
 {% endif %}
{% endfor %}
</ul>

I get a syntax error because % is a symbol reserved for the templating language. This is unfortunate.

I already found a partial solution with

{% cycle "" "" "" '<br style="clear: both"/>' %}

but it strikes me as damn odd. Is there a better way?

Answer 1

forlopp count divisible by 2

{% if forloop.counter|divisibleby:2 == 0 %}

forloop count not divisible by 2

{% if forloop.counter|divisibleby:2 != 0 %}

Answer 2

divisibleby

Returns True if the value is divisible by the argument.

For example:

{{ value|divisibleby:"3" }}
