Django newbie issue. Just trying to understand. I'm setting up a
simple UserProfile class to link to User (as described in several
places in documentation). Here's what I have --- a simple example of
storing the user's website in a profile
#In myapp/models.py
class UserProfile(models.Model):
def __init__(self, website='http://www.default.com'):
super(UserProfile, self).__init__()
self.website = website
user = models.ForeignKey(User, unique=True,
related_name="user_profile") <-- note related_name...see below
website = models.URLField()
#In myproject/settings.py
AUTH_PROFILE_MODULE = "myapp.UserProfile"
Now I create a empty db
run: python2.6 manage.py syncdb
All tables look good in postgres.
Now in the python shell:
Python 2.6.5 (r265:79063, May 12 2010, 10:28:19)
>>> from django.contrib.auth.models import User
>>> from myapp.models import UserProfile
>>> u = User(username='testuser', password='shhhh')
>>> u.save()
>>> up = UserProfile(website='www.overridethesite.com')
>>> up.user=u
>>> up.save()
So far so good
Over in Postgres, everything looks fine:
mydb=> select au.id as id, au.username, up.id as upid, up.user_id as
fk_userid, up.website from auth_user au join myapp_userprofile up on
(au.id=up.user_id);
id | username | upid | fk_userid | website
------+----------+------+-----------+-------------------------
2 | testuser | 1 | 2 | www.overridethesite.com
(1 row)
Now back in the python shell, trying to use the profile from the user
obj:
>>> u.user_profile.values() <--- works fine using the related_name I set in
>>> the UserProfile class
[{'website': u'www.overridethesite.com', 'user_id': 2, 'id': 1}]
### But get_profile() fails:
>>> myprofile = u.get_profile()
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/home/myusername/webapps/django_boosters/lib/python2.6/django/
contrib/auth/models.py", line 370, in get_profile
self._profile_cache =
model._default_manager.using(self._state.db).get(user__id__exact=self.id)

self._result_cache = list(self.iterator())
File "/home/myusername/webapps/django_boosters/lib/python2.6/django/
db/models/query.py", line 282, in iterator
obj = self.model(*row[index_start:aggregate_start])
TypeError: __init__() takes at most 2 arguments (4 given)
Can anyone tell me what's going on, or what I'm doing wrong? Thanks in
advance.
