jquery - interaction Django and Ajax -

i'm trying send data server , use ajax

function stats(e){     jquery.ajax({     type: "post",     url:"stats",     data:{'csrfmiddlewaretoken': document.getelementsbyname('csrfmiddlewaretoken')[0].value, 'test':{}}, success: function(data) {alert("congratulations!"+data);}, error: function(data) { alert("please report error: "+data.responsetext);} }); } 

function in views.py:

def stats(request):     if request.is_ajax():         if request.user.is_authenticated():             if request.post:                 return httpresponse(request.post['test'])             else:                 return httpresponse("post_no_exists")          else:             return httpresponse("no authenticate")     else:         raise http404 

django raise multivaluedictkeyerror 'key "test" not found in querydict'. when change "test":{} -> "test":1 succeds. whats error?

here:

... data: {     'csrfmiddlewaretoken': ...,     'test': {} } ... 

you're trying send empty object literal part of post request. jquery can't figure out value send (empty object? mean?), doesn't send test parameter @ all. thus, on server side, trying access request.post['test'] throws keyerror.

when change test different literal (in case number), jquery can encode , send value.
