How can I add a new database entry upon user registration with Django?

I'm starting to learn Django and have a class called Customer in my models.

class Customer(models.Model):      user = models.OneToOneField(User, on_delete=models.CASCADE,          primary_key=True)      cart = models.ManyToManyField(Product)      orders = models.ManyToManyField(Order)        def __init__(self, user):          self.user = user  

I'm importing django.contrib.auth to register users to the database, but I would like to also initialize a Customer object upon registration.

I first attempted to override the save() method from the UserCreationForm and initialize a Customer object there:

class UserCreationForm(forms.ModelForm):      def save(self, commit=True):          user = super(UserCreationForm, self).save(commit=False)          user.set_password(self.cleaned_data["password1"])          customer = Customer(self)          customer.save()          if commit:              user.save()          return user  

But it did not seem to create a Customer object.

Alternatively, is it better to extend the User class to have the Customer class fields? I initially thought I should keep authentication separate, which is why I created the Customer class.
