Can not parse the remainder: '==0' from 'data.tab_nid==0'

Question

I my template, I want to give a class active:

<li>{% if data.tab_nid==0 %} class="active" {% endif %} </li>

But when I run the page I get the bellow error:

TemplateSyntaxError: Could not parse the remainder: '==0' from 'data.tab_nid==0'

Answer 1

{% if data.tab_nid == 0 %}

You should put space before and after ==

Answer 2

You use == to check the value if is equal, you should put space around ==.

And you can also use ifequal

Just try this:

<li>{% ifequal data.tab_nid 0 %} class="active" {% endifequal %} </li>

From the document, you can find the ifequal & ifnotequal's explain.
