JSON帖子未从Django视图获得响应

Question

So I tried a simple JSON post. But my view on django side doesn't respond at all. JavaScript:

$(function(){
var arr = { 'file': "print \"It works!\"", 'fileName' : "JSONtest", 'fileExt':".py" };

$.ajaxSetup({ 
 beforeSend: function(xhr, settings) {
     function getCookie(name) {
         var cookieValue = null;
         if (document.cookie && document.cookie != '') {
             var cookies = document.cookie.split(';');
             for (var i = 0; i < cookies.length; i++) {
                 var cookie = jQuery.trim(cookies[i]);
                 // Does this cookie string begin with the name we want?
             if (cookie.substring(0, name.length + 1) == (name + '=')) {
                 cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                 break;
             }
         }
     }
     return cookieValue;
     }
     if (!(/^http:.*/.test(settings.url) || /^https:.*/.test(settings.url))) {
         // Only send the token to relative URLs i.e. locally.
         xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));
     }
 } 
});
$.ajax({
    url: '/au',
    type: 'POST',
    data: JSON.stringify(arr),
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    success: function(data) {
        alert(data['link']);
    }
    });
});

view.py:

from django.shortcuts import render_to_response
from django.http import HttpResponse
from django.template import RequestContext, loader
from django.core.files.base import ContentFile
from django.views.decorators.csrf import ensure_csrf_cookie

from quickpad.models import FileLink

from mimetypes import types_map

from random import randint

def upload(request):
    print 'hi'
    genId = ''
    try:
        data=json.loads(request.body)
        file=data['file']
        name=data['fileName']
        ext=data['fileExt']
        newFile = FileLink(fileName=name,fileExt=ext)
        newFile.file.save(name,ContentFile(file))

        while (True):
            genId = ''.join([alphaNum[randint(0,61)] for i in xrange(8)])
            if len(FileLink.objects.filter(fileId=genId)) == 0: break
        print genId
        newFile.fileId = genId
        newFile.save()

    except:
        print 'nope'
    response = HttpResponse()
    csrf(response)
    response['link'] = genId
    return response

The print "hi" statement doesn't show nor does any new objects get created. Any help would be nice. Thanks!

Sorry for the delay, the problem was the ordering in my url.py the default r'^$' was messing with another url for some reason. I finally caught the error after 2 hours of debugging(it was hard to debug cause there were no errors that were showing nor any debug text). Sorry for the confusion, it's my first Django app.
