email exists while authenticating

Using Django
1

Hi,
when authenticating a user in django, i have the following view:

def register(request):
    if request.method == 'POST':
        form = RegisterForm(request.POST)
        if form.is_valid():
            form.save()
            username = form.cleaned_data.get('username')
            email = form.cleaned_data.get('email')
            raw_password = form.cleaned_data.get('password1')
            user = authenticate(username=username, email=email, password=raw_password)
            current_site = get_current_site(request)
            mail_subject = 'Activate your account.'
            message = render_to_string('activation.html', {
                'user': user,
                'domain': current_site.domain,
                'uid': urlsafe_base64_encode(force_bytes(user.pk)),
                'token': default_token_generator.make_token(user),
            })
            to_email = form.cleaned_data.get('email')
            email = EmailMessage(mail_subject, message, to=[to_email])
            email.send(fail_silently=False)
            messages.info(request, 'Check ' + user.email + ' inbox to confirm membership')
            return redirect('home')

    else:
        form = RegisterForm()
    return render(request, 'register.html', {'form': form})

in the forms i was working on email validation if email exists as such:

def clean_email(self):
       email = self.cleaned_data.get('email')
       try:
           match = User.objects.get(email=email)
       except User.DoesNotExist:
           return email
       raise forms.ValidationError('Email address already registered.')

Instead of raising a validation error i want to send an email like in views
messages.info(request, ‘Check ’ + user.email + ’ inbox to confirm membership’)

so i tried the following and got in loads of trouble, trimmed alot from the original to avoid errors and got this:

def clean_email(self):
   email = self.cleaned_data.get('email')
   username = self.cleaned_data.get('username')
   email = self.cleaned_data.get('email')
   raw_password = self.cleaned_data.get('password1')
   user = authenticate(username=username, email=email, password=raw_password)

   try:
       match = User.objects.get(email=email)
   except User.DoesNotExist:
       return email

   mail_subject = 'Request membership'
   message = render_to_string('emailexist.html')
   to_email = self.cleaned_data.get('email')
   email = EmailMessage(mail_subject, message, to=[to_email])
   email.send(fail_silently=False)
   messages.info('Check ' + user.email + ' inbox to confirm membership')
   return redirect('home')

message not working since cant get user.email and if i remove the whole message part i got theis error: ‘HttpResponseRedirect’ object has no attribute ‘strip’

Could i get some support on this, as it seems i strayed far from the right path

Thank you

A clean_ method must return the value to replace that field, so instead of returning redirect, you must return the value for the email field.

This would not be the right location to perform the actions you’re trying to perform.
