[Fixed]-Saving profile with registration in Django-Registration

You can pass the callback function in your urls.py file.

from mysite.profile.models import UserProfile


url( r'^accounts/register/$',      'registration.views.register',
        { 'profile_callback': UserProfile.objects.create }, name = 'registration_register' ),

Substitute your own function for UserProfile.objects.create as needed.

This is covered in this blogpost and expanded on in my answer to another question on the same issue

django-registration sends a signal at various events happening – registration and activation. At either of those points you can create a hook to that signal which will be given the user and request objects – from there you can create a profile for that user.

The signal from django-registration

#registration.signals.py 
user_registered = Signal(providing_args=["user", "request"]) 

Code to create profile

#signals.py (in your project)
user_registered.connect(create_profile)

def create_profile(sender, instance, request, **kwargs):
    from myapp.models import Profile
    #If you want to set any values (perhaps passed via request) 
    #you can do that here

    Profile(user = instance).save()

For anyone who met this problem, I think this blog post is a good tutorial: http://johnparsons.net/index.php/2013/06/28/creating-profiles-with-django-registration/.
