NotImplementedError, Adding custom fields to django-registration?

Question

Django

Good evening. I already asked here about adding two fields to the standard django-registration (not redux) form. Essence of the question: it is necessary to give the user on a level with username , password , email to enter available in the standard User class last_name, first_name.
And so it was done:
forms.py

from registration.forms import RegistrationForm
from django.forms.fields import CharField
from django.contrib.auth.models import User


class UpdatedRegistrationForm(RegistrationForm):
    first_name = CharField(max_length=20)
    last_name = CharField(max_length=30)

    class Meta:
        model = User
        fields = ('username', 'email', 'password1', 'password2')

    def save(self, commit = True):
        user = super(UpdatedRegistrationForm, self).save(commit=False)
        user.first_name = self.cleaned_data['first_name']
        user.last_name = self.cleaned_data['last_name']
        if commit:
            user.save()
            return user

urls.py

from django.conf.urls import include, url
from django.contrib import admin
from accounts.views import home_page, admin_panel
from accounts.forms import UpdatedRegistrationForm
from registration.views import RegistrationView


class RegistrationViewUniqueEmail(RegistrationView):
    form_class = UpdatedRegistrationForm

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^home/', home_page),
    url(r'^admin_pannel/',admin_panel),
    url(r'^register/$', RegistrationViewUniqueEmail.as_view(), name='registration_register'),
    url(r'', include('registration.backends.simple.urls')),
    url(r'', include('social_auth.urls')),


]

When starting the server and going to /register/, now, in addition to the standard username, password1, password2, email , the desired first_name , last_name

are also displayed. After that, we send the data and get the following:


But the data is sent, this is visible in the request body

As a hypothesis, I assume that it is possible the problem is not overridden __init__() for my form. But this is just a hypothesis. I would be grateful for the corrections, and for practical advice.

Answer 1

There is clearly an error here.

if commit:
    user.save()
    return user

Need like this:

if commit:
    user.save()
return user

And the reason for the error on the screenshots is that you need to import it into urls.py

from registration.backends.default.views import RegistrationView

but notfrom registration.views import RegistrationView
