creating a registration profile in python django -

my goal django application upon registration, users able use site, prompt them later verify email (activate it). send them email verification email register, , again if can't find email.

i'm using django 1.7.8 , django-registration-redux.

here's landing page view:

from django.shortcuts import render django.http import httpresponseredirect django.core.urlresolvers import reverse django.contrib.auth import authenticate django.contrib.auth import login  registration import signals registration.models import registrationmanager  drivers.forms import myusercreationform  def create_registration_profile(user, request, **kwargs):     user.backend = 'django.contrib.auth.backends.modelbackend'     login(request, user)     reg_manager = registrationmanager()     reg_profile = reg_manager.create_profile(user)     reg_profile.save()     print "callback reached!"  signals.user_registered.connect(create_registration_profile)  def landing(request):     if request.method == 'post':         form = myusercreationform(request.post)         if form.is_valid():             new_user = form.save()             new_user = authenticate(email=form.cleaned_data['email'], password=form.cleaned_data['password1'])             new_user.username = new_user.email  # custom user has no username, email             signals.user_registered.send(sender='landing', user=new_user, request=request)             login(request, new_user)             return httpresponseredirect(reverse("myapp:dashboard"))         else:             print form.errors     else:         form = myusercreationform()     return render(request, "landing.html", {         'registration_form': form,     }) 

unfortunately, fails on creation of registrationprofile:
