Q:

Use less files in django templates

I've got some trouble to load and compile a less file in my django template. 
First of all I load one main less file in my header.html :
header.html
<link rel="stylesheet" href="/static/lib/bootstrap-.3.2/css/bootstrap.min.css" type="text/css">
<link rel="stylesheet" href="/static/lib/select2-3.5.2/select2.css" type="text/css"/>
<link rel="stylesheet" href="/static/lib/magnific-popup/magnific-popup.css" type="text/css">
<link rel="stylesheet/less" href="/static/less/style.less" type="text/css">

The less is loading without any problem. 
Now I want to load specific less file for a specific django app.  For example, I have an app named "helpdesk" and I want to do something like this :
helpdesk.html
{% block header %}
{{ block.super }}
    <link rel="stylesheet/less" href="/static/helpdesk/less/style_helpdesk.less" type="text/less">
    <script type="text/javascript" src="/static/helpdesk/js/helpdesk.js" charset="utf-8"></script>
{% endblock %}

In this case, less is not loading or compiling.  I tried to use some django modules like django-compressor or django-static-precompiler but I was not able to make them work. 
I looked after this for hours so any help would be really appreciated.  Thank you.

Alright, I retried to use the django-compressor module and it worked ! 
I followed this link which is well explained : http://marklmiddleton.com/2013/using-less-with-django-on-heroku/
