Django - using django-registration app with signals

Ok, so I've built a basic Django Project and successfuly installed the django-registration app - http://www.michelepasin.org/blog/2011/01/14/setting-up-django-registration/

I want to expand a User to include information like Birthday, Profile Picture etc. I created an app called user_profile. This is the signals.py inside the registration app:

from django.dispatch import Signal
user_activated = Signal(providing_args=["user", "request"])

From inside my new app, user_profile, what is the way to listen for this signal? I think I should create a signals.py file, but what should I write inside? a from registration.signals import user_activated statement and what else? This new app which I've created also has a model.py which I want to automatically populate with some data when a new account has been activated.

And another secondary question: when I link a URL with a class based view, which method of that class is triggered? If I have 4 methods inside inside the class based view, how django decides which one to use? Thanks

Thanks Eliot, here is what I have so far:

signals.py is now removed.

models.py:

    import datime

from django.db import models
from django.contrib.auth.models import User

try:
    from django.utils.timezone import now as datetime_now
except ImportError:
    datetime_now = datetime.datetime.now

class UserProfileManager(models.Manager):

    def create_user_profile(self, user):
        user_profile = self.create(user = user)
        return user_profile

class UserProfile(models.Model):

    YEARS = tuple(zip(range(1900, datetime_now.year)), zip(range(1900, datetime_now.year)))
    MONTHS = (
              ('January','January'),('February','February'),('March','March'),('April','April'),
              ('May','May'), ('June','June'),('July','July'),('August','August'),
              ('September','September'),('October','October'),('November','November'), ('December', 'December')

             )
    GENDERS = (('M', 'Male'), ('F', 'Female'))

    user = models.ForeignKey(User, unique=True, verbose_name=_('user'))
    birthday_year = models.CharField(max_length=1, blank = True,  null = True, choices=YEARS)
    birthday_month = models.CharField(max_length=1, blank = True,  null = True, choices=MONTHS)
    gender = models.CharField(max_length=1, blank = True,  null = True, choices=GENDERS)
    creation_time = models.DateTimeField(auto_now_add = True, auto_now = False)
    update_time = models.DateTimeField(auto_now_add = False, auto_now = True)

    class Meta:
            verbose_name = _('user profile')
            verbose_name_plural = _('user profiles')

    objects = UserProfileManager()

def create_user_profile(sender, instance, **kwargs):
    profile = UserProfile.objects.create_user_profile(user=instance)
    profile.save()

post_save.connect(create_user_profile, sender=User)

OKay, if I understand your problem, you'll have put something like this at the end of your user_profile/models.py file :

from django.contrib.auth.models import User
from django.db.models.signals import post_save

def create_user_profile(sender, instance, **kwargs):
    """ 
        Function to create user profile. 
        sender is the model class that sends the signal,
        while instance is an actual instance of that class
    """

    # your own logic here, for example :

    user = instance
    profile = UserProfile()
    profile.user = user  # link the profile to the user
    profile.save()

# connect the function to the signal, for User instances)
post_save.connect(create_user_profile, sender=User)

For your second question, many methods are called during class based views execution. In order to use class based views, your URLconf should look like this :

from myapp import views
from django.conf.urls import patterns, url

urlpatterns = patterns('',
    url(r'list_something', views.YourListView.as_view(), name="list_something"),
)

But you should not override as_view() method in your view. Depending on what you're trying to do, you'll have other methods to overwrite. I can maybe help you if you provide more info.
