如何将注册期间指定的信息自动添加到“个人资料”？ Django 2.1.5

Question

I matched Profile with User by OneToOne with signals. I created SignUpForm with additional fields ( location , email , firstname etc) and email confirmation.

How make the this info ( location , email , firstname etc) automacally added to Profile ?

I think, this really make with

user.refresh_from_db()
user.profile.<...>=form.cleaned_data.get('<...>')

but I don't know how.

models.py

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    first_name = models.CharField(max_length=30, blank=True, default='', null=True)
    location = models.CharField(max_length=30, blank=True, default='')
    email = models.EmailField(max_length=30, blank=True, default='', null=True)

    class Meta:
        ordering = ["location"]

    def get_absolute_url(self):
        return reverse('profile-detail', args=[str(self.id)])

    def __str__(self):
        return self.user.username

forms.py

class SignupForm(UserCreationForm):
    email = forms.EmailField()
    location = forms.CharField()

    class Meta:
        model = User
        fields = ('username', 'email', 'location', 'password1', 'password2')


class ProfileForm(forms.ModelForm):
    class Meta:
        model = Profile
        exclude = ('user', )

signals.py

@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
    if created:
        Profile.objects.create(user=instance)

admin.py

class ProfileAdmin(admin.ModelAdmin):
    list_display = ('user', 'location', 'email', 'first_name')

views.py

def signup(request):
    if request.method == 'POST':
        form = SignupForm(request.POST)
        if form.is_valid():
            user = form.save(commit=False)
            user.is_active = False
            user.save()
            current_site = get_current_site(request)
            mail_subject = 'Activate your blog account.'
            message = render_to_string('acc_active_email.html', {
                'user': user,
                'domain': current_site.domain,
                'uid':urlsafe_base64_encode(force_bytes(user.pk)).decode(),
                'token':account_activation_token.make_token(user),
            })
            to_email = form.cleaned_data.get('email')
            email = EmailMessage(
                        mail_subject, message, to=[to_email]
            )
            email.send()
            return HttpResponse('Please confirm your email address to complete the registration')
    else:
        form = SignupForm()
    return render(request, 'signup.html', {'form': form})


def activate(request, uidb64, token):
    try:
        uid = force_text(urlsafe_base64_decode(uidb64))
        user = User.objects.get(pk=uid)
    except(TypeError, ValueError, OverflowError, User.DoesNotExist):
        user = None
    if user is not None and account_activation_token.check_token(user, token):
        user.is_active = True
        user.save()
        login(request, user)
        # return redirect('home')
        return HttpResponse('Thank you for your email confirmation. Now you can login your account.')
    else:
        return HttpResponse('Activation link is invalid!')

I think you can put the additional data in the view method . You can try like this:

# form

class SignupForm(UserCreationForm):
    location = forms.CharField()

    class Meta:
        model = User
        fields = ('username', 'email', 'location', 'password1', 'password2')

# view

def signup(request):
   ...
   location = form.cleaned_data.get('location')
   user = form.save(commit=False)
   user.is_active = False
   user.save()
   profile = user.profile
   profile.location = location
   profile.save()
   ...

Here I am not adding email and firstname in the form or in the profile, because if you are using default auth.User model, then these data are available in the Model already. For that, please see then AbstractBaseUser implementation.
