Just upgraded to Django 1.4 and getting error with messages

I just upgraded to Django 1.4 and it has broken a couple things including messaging.

Here's the error I get when trying to change a avatar:

'User' object has no attribute 'message_set'
Exception Location: /Users/nb/Desktop/myenv2/lib/python2.7/site-packages/django/utils/functional.py in inner, line 185

Traceback:

File "/Users/nb/Desktop/myenv2/lib/python2.7/site-packages/django/core/handlers/base.py" in get_response
  111.                         response = callback(request, *callback_args, **callback_kwargs)
File "/Users/nb/Desktop/myenv2/lib/python2.7/site-packages/django/contrib/auth/decorators.py" in _wrapped_view
  20.                 return view_func(request, *args, **kwargs)
File "/Users/nb/Desktop/spicestore/apps/avatar/views.py" in change
  76.             request.user.message_set.create(
File "/Users/nb/Desktop/myenv2/lib/python2.7/site-packages/django/utils/functional.py" in inner
  185.         return func(self._wrapped, *args)

Exception Type: AttributeError at /avatar/change/
Exception Value: 'User' object has no attribute 'message_set'

Also, messaging no longer works on the site. What are the changes in Django 1.4 that could be causing this and has anyone overcome a similar issue?

Add

from django.contrib import messages

And then

def foo(request):
    messages.add_message(request, messages.INFO, "Your message.")

From Django 1.4 docs To enable message functionality, in settings.py do the following:

Edit the MIDDLEWARE_CLASSES setting and make sure it contains

'django.contrib.messages.middleware.MessageMiddleware'

If you are using a storage backend that relies on sessions (the default), django.contrib.sessions.middleware.SessionMiddleware must be enabled and appear before MessageMiddleware in your MIDDLEWARE_CLASSES.

Edit the TEMPLATE_CONTEXT_PROCESSORS setting and make sure it contains

'django.contrib.messages.context_processors.messages'

Add 'django.contrib.messages' to your INSTALLED_APPS setting

As far as django-avatar is concerned. Use the master files found here: https://github.com/chadpaulson/django-avatar/tree/master/avatar

Django introduced a messages app in 1.2 (release notes), and deprecated the old user messages API.

In Django 1.4, the old message_set API has been removed completely, so you'll have to update your code. If you follow the messages docs, you should find it pretty straight forward.

What is in your INSTALLED_APPS in your settings.py?

Do you have 'django.contrib.messages', included there?

Something like:

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.humanize',
    ...
