问题
I have found here on stackoverflow a solution to extend django-registration with new fields using signals. Here's the link : http://dmitko.ru/?p=546 .
I have created extended profile model, extended form, added required options to settings , defined urls and the proper form is displayed but only normal User (from auth module) is created. Why is that happening ?
account.models :
from django.db import models
from django.contrib.auth.models import User
from registration.signals import user_registered
import hashlib
class InheritedProfile(models.Model):
first_name = models.CharField("Name", max_length=50, blank=True, null=True)
last_name = models.CharField("Last name", max_length=50, blank=True, null=True)
pid = models.CharField("PESEL", max_length=11, blank=True, null=True)
street = models.CharField("Street", max_length=50, blank=True, null=True)
number = models.CharField("Flat/house number", max_length=10, blank=True, null=True)
code = models.CharField("Zip ", max_length=6, blank=True, null=True)
city = models.CharField("City", max_length=50, blank=True, null=True)
class Meta:
abstract=True
class UserProfile(InheritedProfile, User):
def upload_path(self, field_attname):
filename = hashlib.md5(field_attname).hexdigest()[:4] + "_" + field_attname
return "uploads/users/%s" % (filename,)
image = models.ImageField(upload_to=upload_path, verbose_name="Image", blank=True, null=True)
def user_created(sender, user, request, **kwargs):
form = ExtendedRegistrationForm(request.POST)
extended_user = UserProfile(user=user)
extended_user.is_active = False
extended_user.first_name = form.extended_user['first_name']
extended_user.last_name = form.extended_user['last_name']
extended_user.pid = form.extended_user['pid']
extended_user.image = form.extended_user['image']
extended_user.street = form.extended_user['street']
extended_user.number = form.extended_user['number']
extended_user.code = form.extended_user['code']
extended_user.city = form.extended_user['city']
extended_user.save()
user_registered.connect(user_created)
I need this InheritedProfile to be abstract as other models will use the same fields.
account.forms
from django import forms
#import strings
from registration.forms import RegistrationForm
from models import UserProfile, InheritedProfile
class ExtendedRegistrationForm(RegistrationForm):
first_name = forms.CharField(widget=forms.TextInput(attrs=dict(attrs_dict, maxlength=50)), label="First name")
last_name = forms.CharField(widget=forms.TextInput(attrs=dict(attrs_dict, maxlength=50)), label="Last name")
pid = forms.RegexField(regex=r'^\d{11}', max_length=11 ,widget=forms.TextInput(attrs=dict(attrs_dict, maxlength=50)))
image = forms.ImageField(label="Image",)
street = forms.CharField(widget=forms.TextInput(attrs=dict(attrs_dict, maxlength=50)), label="Street")
number = forms.CharField(widget=forms.TextInput, label="House/flat number")
code = forms.RegexField(regex=r'^\d{2}[-]\d{3}', max_length=6, widget=forms.TextInput(attrs=attrs_dict), label="Postal code")
city = forms.CharField(widget=forms.TextInput, label="City")
and options added to settings :
AUTH_PROFILE_MODULE = 'account.UserProfile'
ACCOUNT_ACTIVATION_DAYS = 7
finally this is how the registration signal looks like :
from django.dispatch import Signal
# A new user has registered.
user_registered = Signal(providing_args=["user", "request"])
EDIT: Indentation of user_created changes nothing until I've tried changing
user_registered.connect(user_created)
to
user_registered.connect(user_created, sender=UserProfile)
Now I was getting :
"SMTPServerDisconnected
Exception Location: /bin/python-2.6.1/lib/python2.6/smtplib.py in getreply, line 340 "

340. raise SMTPServerDisconnected("Connection unexpectedly closed")
Exception Type: SMTPServerDisconnected at /user/register/
Exception Value: Connection unexpectedly closed
Even though I'm using dummy email backend at the moment. Commenting out sending mail function upon registration solved this problem but still my extended user is not created.

May be the problem is in the way how you connect to the signal? In my solution in was:
def user_created(sender, user, request, **kwargs):
form = UserRegistrationForm(request.POST)
data = profile.Profile(user=user)
data.city_id = form.data["city"]
data.save()
from registration.signals import user_registered
user_registered.connect(user_created)
and in yours:
from django.dispatch import Signal
# A new user has registered.
user_registered = Signal(providing_args=["user", "request"])
Also, I would switch on logging to ensure that your method is called. My solution works fine in the production, if you need I can look for other details.
