[Django]-Create User and UserProfile on user signup with django-allauth

How to create a User and a UserProfile on signup?

You can create a UserProfile at the same time you save the CustomSignupForm

def save(self, request):
    user = super(CustomSignupForm, self).save(request)
    user.first_name = self.cleaned_data['first_name']
    user.last_name = self.cleaned_data['last_name']
    user.bio = self.cleaned_data['bio']
    user.save()
    
    # Create your user profile
    UserProfile.objects.create(user=user, first_name=self.cleaned_data['first_name'], last_name=self.cleaned_data['last_name'], email=self.cleaned_data['email'], bio=self.cleaned_data['bio'])

Another elegant way is to use Django signals to perform some actions after that an event occur like user creation.

signals.py

from django.db.models.signals import post_save
from django.dispatch import receiver
from .models import UserProfile

@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
    if created:
        first_name = instance.first_name
        last_name = instance.last_name
        email = instance.email
        # The bio field is not set because the User instance has not bio attribute by default.
        # But you can still update this attribute with the profile detail form.
        UserProfile.objects.create(user=instance, first_name=first_name, last_name=last_name, email=email)

If you want to update the profile each time an user is updated, then remove the if created in the signal body.

apps.py

class AppNameConfig(AppConfig):
    
    # some code here

    # import your signal in the ready function
    def ready(self):
        import app_name.signals
