Sending array to django via ajax

Question

I am trying to send Javascript Array via AJAX POST to django view.

I store this array in hidden input using JSON.stringify:

$('#id_uuids').val(JSON.stringify(arr));

this is how I try to send it:

$.post("/ajax/generateGallery",{uuids: $('#id_uuids').val()},function(response){
    resp = JSON.parse(response);
    alert(resp.html);
},"json");

Browser console shows that data which is being send looks like:

uuids:["6ecbe35b-0b77-4810-aa9a-918fecaeef13","e41f52f7-721b-4d44-b7d6-bbb275182d66"]

However, I am not able to use this in my django view. I've tried:

uuids = request.POST.getlist('uuids')
logger.info(uuids)
logger.info(type(uuids))

which returns:

[08/Aug/2014 15:20:00] INFO [app.rest_client:307] [u'["89a26646-6000-4c48-804a-69abcc496fd8"]']
[08/Aug/2014 15:20:00] INFO [app.rest_client:308] <type 'list'>
[08/Aug/2014 15:20:00] INFO [app.rest_client:312] Generate HTML gallery for photo ["89a26646-6000-4c48-804a-69abcc496fd8"]

So, Django treats very list sent as single element. How can I force python code to treat this data as list and be able to iterate on?

The problem is that you stringify the array, and it's submitted as string, this is not a Django issue but rather how you handle values in JS. — petkostas

try to JSON-decode the posted data

uuids = json.loads(request.POST.get('uuids'))

that is if you loaded some json module before, e.g.

import simplejson as json
