javascript-readable json from python

Question

My view computes a json and outputs a json.dumps(), and I'm passing this as the dictionary key data. I'm trying to pass this to a script element in my template, but when rendering, the browser gets it as a python-escaped string{"nodes": [{"count":...... which isn't readable to the javascript. What I need is python to send it as a JS-escaped string, something like this {"nodes": [{"count":....... I tried str(data) and eval(data) without success. Basically I need python to send the string just as if it were printing it to the console. Thanks

is this question of any help to you? http://stackoverflow.com/q/1445989/92493 — Otto Allmendinger, Jul 19 '12 at 19:57
I believe that if you're rendering it to your HTML template and that this HTML template will be send to the browser using the mime type 'text/html' (or it's variant) than the browser will escape the quotes and such, so i think it really depend on the mime type that you're sending to the browser. — mouad, Jul 19 '12 at 20:00

If I understand well, you want to use a json in a template. In order to do that, you have to disable the escaping, for exemple like this.

{% autoescape off %}
var x={{json_var}}
{% endautoescape %}

Note that instead of using

{% autoescape off %}
    {{ my_json }}
{% endautoescape %}

You can simply use a filter :

{{ my_json|safe }}

This works for me:

return HttpResponse(json.dumps({'foo' : 'bar'}, ensure_ascii=False),
    mimetype='application/json')

I use something like this when sending a simple HttpResponse, but in this case I had to render a template. – leonsas Jul 19 '12 at 20:17
