Dajaxice. Cannot call method "..." from undefined. Again

I am stuck trying to create a simple application with dajaxice. I read all the topics about this problem here, and here you not only rewrite all the code many times, but you also don’t see what the problem is. the most interesting thing is that these examples work (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

my tools:

  • Windows 7 64
  • python 2.7.3
  • Django-1.4.2
  • Django-dajaxice-0.2

Project Structure:

 BlocalProject/ templates/ template_1.html manage.py BlocalProject/ ajapp/ __init__.py ajview.py __init__.py settings.py urls.py views.py wsgi.py

urls.py:

 from django.conf.urls.defaults import * import settings from dajaxice.core import dajaxice_autodiscover dajaxice_autodiscover() urlpatterns = patterns('', (r'^%s/' % (settings.DAJAXICE_MEDIA_PREFIX), include('dajaxice.urls')), (r'^$', 'BlocalProject.views.start_page'), )

views.py:

 from django.shortcuts import render def start_page(request): return render(request,'template_1.html')

ajapp.py:

 from django.utils import simplejson from dajaxice.core import dajaxice_functions def sayhello(request): return simplejson.dumps({'message': 'Trololo!'}) dajaxice_functions.register(sayhello)

template_1.html:

 {% load dajaxice_templatetags %} <html> {% dajaxice_js_import %} <script> function alertMessage(data){ alert(data.message); return false; } </script> <body> Some text <input type="button" value="Get!" onclick="Dajaxice.ajapp.sayhello(alertMessage);" /> </body> </html>

settings.py:

It may be too late, but ...

IMHO, dajaxice_autodiscover() does not actually get your method. I remember that I had a similar problem with another ajax lib, and I solved it by adding import to models.py (or views.py ), which are imported when the application 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 initializing material. My approach:

  • put some prints in ajapp.py and see if they print.
  • create empty models.py and views.py in your BlocalProject.ajapp ( BlocalProject.ajapp django still use models.py to test the module as a django application?)

If your print instructions do not start, you need to find out why. As I mentioned, this can be as simple as importing your ajax module into the model :)
