Answer 1

I found a way to do this! (The last answer was throwing me some errors) Let me explain it: (Django 1.10.5 and Django-registration-redux 1.4)

app/models.py:

class Profile(models.Model):
    user = models.OneToOneField(User, primary_key=True)
    passport_id = models.IntegerField(max_length=10)

app/forms.py:

from registration.forms import RegistrationFormUniqueEmail
from django import forms
from .models import Profile


class ProfileForm(RegistrationFormUniqueEmail):
    passport = forms.IntegerField(max_length=10)

Then, I made the -famous- regbackend.py file. Note that the register method takes only one parameter (the form). You need to remember to create -and save- the new object (record) in the DB's model's table aswell, as I do in the following code:

app/regbackend.py

from registration.backends.default.views import RegistrationView
from .forms import ProfileForm
from .models import Profile


class MyRegistrationView(RegistrationView):

    form_class = ProfileForm

    def register(self, form_class):
        new_user = super(MyRegistrationView, self).register(form_class)
        p = form_class.cleaned_data['passport']
        new_profile = Profile.objects.create(user=new_user, passport=p)
        new_profile.save()
        return new_user

root/urls.py

from app.regbackend import MyRegistrationView


urlpatterns = [
    url(r'^accounts/register/$', MyRegistrationView.as_view(),
        name='registration_register'),
    url(r'^accounts/', include('registration.backends.default.urls'))]

After this, You may want to setup some other things for the field (Validations, etc.)

Answer 2

It's works for me:
models.py

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

class UserProfile(models.Model):
    field = models.CharField(max_length=3)
    user = models.OneToOneField(User)

forms.py

from registration.forms import RegistrationFormUniqueEmail
from django import forms

class UserProfileRegistrationForm(RegistrationFormUniqueEmail):
    field = forms.CharField()

Create regbackend.py and write:

from registration.backends.default.views import RegistrationView
from forms import UserProfileRegistrationForm
from models import UserProfile

class MyRegistrationView(RegistrationView):

    form_class = UserProfileRegistrationForm

    def register(self, request, form_class):
        new_user = super(MyRegistrationView, self).register(request, form_class)
        user_profile = UserProfile()
        user_profile.user = new_user
        user_profile.field = form_class.cleaned_data['field']
        user_profile.save()
        return user_profile

And urls.py

from django.conf.urls import include, url
import regbackend

urlpatterns = [
url(r'^accounts/register/$', regbackend.MyRegistrationView.as_view(), name='registration_register'),
]
