[Django]-Complex comparisons on yesno filter?

✅

The problem is simply with your syntax in the code you posted:

{{l.code=="es"|yesno:"disabled,"}}

It’s actually processed like:

{{ l.code=={{"es"|yesno:"disabled,"}} }}

(Note: that code doesn’t work, it’s just meant to illustrate how Django reads it)

What you want is a custom template tag that works like the if templatetag but returns like the yesno filter. You could search around on something like djangosnippets.com; maybe someone has already done the work for you. Otherwise, I’d suggest looking at the Django source code for those two and try to merge them into your own templatetag.

Or you could use jQuery/javascript to set the class:
http://api.jquery.com/attr/
something like this – not tested!

{% get_language_info for LANGUAGE_CODE as l %}

<script>
{% if l.code='es' %}
  $('.english').attr('class','disable');
{% else %}
  $('.english').attr('class','disable');
{% endif %}
</script>



<a href="/path/to/switch/to/spanish" 
   id="spanish" class='enable">
   <img src="/spanish/flag/url" alt="Spanish" >
</a>
<a href="/path/to/switch/to/english" 
   id="english" class='enable">
   <img src="/english/flag/url" alt="English">
</a>
