The link to the faulty documentation is given at the very end of this
entry.
Dear all,
I have difficulties with the get_profile to link my Profile class with
the inbuilt User object.
The error message (which can be obtained through the 'chatroom' view
shown below, or via the shell) is:
---------------------------------------------------------------------------
AttributeError Traceback (most recent call

/Library/Frameworks/Python.framework/Versions/4.0.30002/lib/python2.5

291 app_label, model_name =
settings.AUTH_PROFILE_MODULE.split('.')
292 model = models.get_model(app_label, model_name)

294 except (ImportError, ImproperlyConfigured):
295 raise SiteProfileNotAvailable
AttributeError: 'NoneType' object has no attribute '_default_manager'
This indicates that models.get_model() does return None, but I don't know
why.
I have in settings.py:
AUTH_PROFILE_MODULE = 'people.profile'
which I believe is the right entry.
For clarity, I have created a small django-site that can be downloaded in
a tar file as:
http://www.soton.ac.uk/~fangohr/geheim/django/get_profile/debug.tar.gz
or can be viewed online in the untarred version at
http://www.soton.ac.uk/~fangohr/geheim/django/get_profile/debug
I summarise the most important elements below (so that this email can
stand on its own for the archives):
mysite/People/models.py contains:
#-----------
from django.contrib.auth.models import User
from django.db import models
class Profile(models.Model):
user = models.ForeignKey(User,unique=True)
homepageURL=models.URLField('homepage',blank=True)
class Admin:
pass
#-----------
The corresponding view (which fails) is in mysite/People/views.py:
#-----------
from django.contrib.auth.models import User
from django.contrib.auth.decorators import login_required
def chatrooms(request):
u = User.objects.get(pk=1) # Get the first user
user_address = u.get_profile().homepageURL
#at this point we get an error, equivalent to shell example
#-----------
The mysite/settings.py reads
#-----------
# Django settings for mysite project.

I have checked other entries on the mailing list, but couldn't find the
solution to this problem.
Any help is very welcome.
Many thanks,
Hans
PS Version:
phi:mysite fangohr$ python manage.py --version
1.0.2 final
PPS In the database for this example, the admin user is 'admin' and
the password is 'admin' -- in case anybody wants to play with that.
Solution (Karen Tracey):
(Thanks for the very detailed question.) I think you have found a
documentation bug. I do not believe the 'people' part of that should be
normalized to lower case. It is not normalized to lower case in
INSTALLED_APPS, and I don't think it should be normalized to lower case
here. Since you have a capital P in People for your directory name, try
'People.profile'.
Karen
Note: Changing people.profile to People.profile solves the problem.
Related documentation: http://docs.djangoproject.com/en/dev/topics/auth
/#auth-profiles
Here it says under 1.: "The (normalized to lower-case) name of the
application in which the user profile model is defined (in other words, an
all-lowercase version of the name which was passed to manage.py startapp
to create the application)."
This is wrong.
