Handlebars.js in Django templates

I wrote a very small django application : django-templatetag-handlebars exactly for that purpose.

{% load templatetag_handlebars %}

{% tplhandlebars "tpl-infos" %}
    {{total}} {% trans "result(s)." %}
    <p>{% trans "Min" %}: {{min}}</p>
    <p>{% trans "Max" %}: {{max}}</p>
{% endtplhandlebars %}

Render your block as usual using Handlebars.js API :

var properties = {
    total: 10,
    min: 5,
    max: 4
};

var template = Handlebars.compile($('#tpl-infos').html()),
    rendered = template(properties);

I wrote it the day @chrisv published its package, with a KISS approach in mind. It is mainly based on Miguel Araujo's gist : https://gist.github.com/893408.

I use a custom template tag for another js templating system, here: https://gist.github.com/629508

Use in template:

{% load mytags %}
{% verbatim %}
  {{ This won't be touched by {% django's %} template system }}
{% endverbatim %}

Edit: This custom template tag is no longer necessary, as Django's template language now supports the {% verbatim %} template tag.

Is there a tag in django templates to stop rendering a block with curly braces?

OLD Answer for Django 1.0-1.4: No, though you could though you could put the block in a separate file and include it without rendering or use a different templating engine.

New Answer: The answer above was correct in August 2011 when the question was asked and answered. Starting in Django 1.5 (released Feb 2013, though alpha/beta versions in late 2012), they introduced the {% verbatim %} and {% endverbatim %} which will prevent the django template engine from processing the content in the block.

So for the question asked the following will work in django 1.5+ out of the box:

{{ django_context_varable }} #works
{% verbatim %}
<script id="restaurants-tpl" type="text/x-handlebars-template">
    <ul>
    {{#restaurants}} #not rendered by django, plain text
    <li>{{name}}</li>
    {{/restaurants}}
    </ul>
</script>
{% endverbatim %}

The documentation on verbatim is here. Yes, this was noted by others earlier, but as this is the accepted answer I should list the easiest solution.
