The view should be like this, btw:
def photo_upload(request):
form = PhotoUploadForm()
if request.POST:
form = PhotoUploadForm(request.user, request.POST,
request.FILES)
if form.is_valid():
form.save()
json = {'status': 'success', 'message': _("Upload
succeeded.")}
return JsonResponse(json)
json = jsonify(form)
return JsonResponse(json)
