Extending django-registration using signals

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_开发者_Go百科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 "

Traceback:

  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.
