I'm stuck in trying to create a simplest application with dajaxice. I'n read all topics about this problem here and not only here, rewrite all code many times, but still do not see what the problem is. the most interesting that, these examples are working (almost all): https://github.com/jorgebastida/django-dajaxice/downloads dajaxice-examples.tar.gz
But in my project i have this:
Uncaught TypeError: Cannot call method 'sayhello' of undefined

This might be too late, but...
IMHO, the dajaxice_autodiscover() doesn't actually get your method. I remember having a similar problem with another ajax lib and I've solved it by adding an import in the models.py (or views.py), which get imported when the app starts. The example you mention has an import in simple/views.py:
# Create your views here.
from django.shortcuts import render
# THIS ONE!
from dajaxice.core import dajaxice_functions
# ---------
def index(request):
return render(request, 'simple/index.html')
which looks like it's initialising stuff. My approach would be:
ajapp.py and see if they get printed out.models.py and views.py in your BlocalProject.ajapp (does django still use models.py to validate a module as a django app?)If your print statements don't get triggered, then you need to find out why. As I mentioned, it might be as simple as importing your ajax module in models :)
