Hello Friends,
I am trying to extend user model to setup email as username. Everything
works find when I create new user using django admin I get error “Manager
isn't available; User has been swapped” when try to create user using
signup view.
There is very few articles on this error. Any help would be appreciated.
Also, the login thing is working perfectly.
I have defined
AUTH_USER_MODEL = 'user_management.CustomUser'
AUTHENTICATION_BACKENDS = ('user_management.manager.CustomUserAuth',)
My code is as follows
----------------------------------
Signup view
--------------------------------
def signup(request):
form= CustomUserCreationForm(request.POST or None)
if request.POST and form.is_valid():
print "test2"
form.save(commit=False)
email=form.cleaned_data['email']
password=form.cleaned_data['password1']
CustomUser.objects.create_user(email=email,password=password)
user=CustomUser.objects.get(email=email)
user.is_active=0
user.save()
print email
salt =
hashlib.sha1(str(random.random())).hexdigest()[:5]
activation_key = hashlib.sha1(salt+email).hexdigest()
key_expires = timezone.datetime.today() + timedelta(days=2)
if user:
return HttpResponseRedirect('/signup_success')
return render(request,'user_management/signup.html',{'form':form})

I hope I included enough for someone to help me. Not sure but I hardly got
any help from this group.
