Adding field to Profile when creating User - django

Question

I have a signup form that looks like this:
class SignUpForm(UserForm):
username = forms.CharField(max_length=32, min_length=1)
initials = forms.CharField(max_length=3)
password = forms.CharField(widget=forms.PasswordInput())
confirm_password = forms.CharField(widget=forms.PasswordInput())'
...
I'm creating the user like this:
class SignUpView(FormView, LoginErrorView):
form_class = SignUpForm
template_name = "website/sign_up.html"
def form_valid(self, form):
User.objects.create_user(username=form.cleaned_data['username'],
email=form.cleaned_data['email'],
password=form.cleaned_data['password'])
....
The Profile model looks like this:
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
initials = models.CharField(max_length=3)
....
I'm creating the profile like this:
#receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
if created:
Profile.objects.create(user=instance)
#receiver(post_save, sender=User)
def save_user_profile(sender, instance, **kwargs):
instance.profile.save()
What I would like to do is to save initials in post_save/create_user_profile (in the Profile-model) from the SignUpForm when I'm creating the Profile object, but I can't figure out any simple way of doing this. Any ideas?

Answer 1

You can save profile just after saving user. Try this:
class SignUpView(FormView, LoginErrorView):
form_class = SignUpForm
template_name = "website/sign_up.html"
def form_valid(self, form):
user = User.objects.create(username=form.cleaned_data['username'],
email=form.cleaned_data['email'],
password=form.cleaned_data['password'])
Profile.objects.create(user=user, initials=form.cleaned_data['initials'])
Remove post_save. I hope this will work. If not, please comment.
