У меня есть приложение Django и пытаюсь использоватьdjango-registration приложение в нем. И ниже мои настройки и коды

settings.py

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.admin',
    'south',
    'registration',
    'user_profile',
 )

AUTH_PROFILE_MODULE = "user_profile.UserProfile"
AUTHENTICATION_BACKENDS = (
    'django.contrib.auth.backends.ModelBackend',
)

проектurls.py файл

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    url(r'^accounts/', include('user_profile.urls')),
    url(r'^accounts/', include('registration.backends.default.urls')),
 )

user_profile urls.py файл

from registration.views import RegistrationView

urlpatterns = patterns('',
    url(r'^register/
user_profile.backends.py файл
from .forms import RegistrationForm
from user_profile.models import UserProfile
from registration.views import RegistrationView

class RegistrationBackend(RegistrationView):
    def get_form_class(self, request)
        return RegistrationForm

    def register(self, request, **kwargs):
        kwargs["username"] = kwargs["email"]
        user = super(RegistrationBackend, self).register(request, **kwargs)
        UserProfile.objects.create(user=user)
        return user
Так из приведенного выше кода, когда пользователь нажимает URLlocalhost:8000/accounts/register Форма регистрации будет отображаться, и после ввода всех полей (username,email, password, password) и нажал нарегистр Кнопка Я получаю нижеNotImplementedError

при попытке зарегистрировать пользователя я получил ошибку ниже
