Simple template filter to encode a variable to JSON format

Usage:

{% load json_filters %}

{% block content %} &lt;script type="text/javascript"&gt;<![CDATA[ var items = {{ items|jsonify }}; ]]>&lt;/script&gt; {% endblock %}

I'm using JsonResponse for the views but I also want to have preloaded JSON data into the page output

from django.core.serializers import serialize
from django.db.models.query import QuerySet
from django.utils import simplejson
from django.template import Library

register = Library()

def jsonify(object):
    if isinstance(object, QuerySet):
        return serialize('json', object)
    return simplejson.dumps(object)

register.filter('jsonify', jsonify)

if you pass simplejson.dumps a kwarg cls=django.core.serializers.json.DjangoJSONEncoder you get handling of datetime objects and decimals for free

You may want to use mark_safe on the results. In Django 1.2 I get HTML escaped quotation marks.
