Question

views.py:

def get_accounts( request ):
    if request.is_ajax():
        res = ["foo","bar"]
        json = simplejson.dumps(res)
        return HttpResponse(json, mimetype='application/json')
    return HttpResponseNotFound

urls.py:

   ( r'^get_accounts/$', 'get_accounts'),

client.html:

$.get('/django/backoffice/bopanel/get_accounts',{'acc':$('.nr').text().replace(/^\s+||\s+$/g,'')}, function(data) {
  alert(data[0]);      
  });

I was very surprised getting an alert box with content:

"["

What means I got string instead of array, which i very strange for me and definitely not something what i expected.

In firebug i see two subsequent GET requests:

GET http://127.0.0.1:8000/django/backoffice/bopanel/...nts?acc=17114%2FF01055%2FTP%0A%09%09++++++++++++
301 MOVED PERMANENTLY
    24ms

GET http://127.0.0.1:8000/django/backoffice/bopanel/...ts/?acc=17114%2FF01055%2FTP%0A%09%09++++++++++++
200 OK
    16ms

I don’t understand why I get two requests and why the first have 301 status. I don’t understand how this makes json appear as string. Any help?

Django by default appends a slash to any URL without one (see common middleware).

You want to use content_type instead of mimetype, ie:

return http.HttpResponse(json.dumps(res), content_type='application/json')
