[FIXED] How to register user using your own Model Django

Issue

I am having trouble registering a user as a PetOwner. I'm not sure what I am suppose to code in my signup view. I can signup a user and that user does not have admin or staff status which is great because they should not have these privileges. Problem is that I do not just want them to be a user but I want them to be a PetOwner. Currently, they are only a User not a PetOwner. What am I doing wrong here or what do I have to add.

in models.py

from django.db import models
from django.urls import reverse
from django.contrib.auth.models import User


class PetOwner(models.Model):
    """Model representing a pet owner."""

    user = models.OneToOneField(User, on_delete=models.CASCADE)
    first_name = models.CharField(max_length=50, help_text="Enter owner's first name")
    last_name = models.CharField(max_length=50, help_text="Enter owner's last name")
    email = models.EmailField(
        max_length=50, blank=True, unique=True, help_text="Enter owner's email"
    )
    phone_number = models.CharField(
        max_length=15, blank=True, unique=True, help_text="Enter owner's phone number"
    )
    address = models.ForeignKey(
        "Address", on_delete=models.SET_NULL, null=True, blank=True
    )

    class Meta:
        """Controls default ordering of records when querying the Model type."""

        ordering = ["first_name", "last_name"]

    def __str__(self):
        """String for representing the Model object."""
        return self.first_name

    def get_absolute_url(self):
        """Returns the url to access a detail record of this pet owner."""
        return reverse("petowner_detail", args=[str(self.id)])

in views.py

from django.shortcuts import render, redirect
from django.views import generic
from django.contrib.auth import authenticate, login, logout
from django.contrib.auth.decorators import login_required
from django.contrib.auth.forms import AuthenticationForm, UserCreationForm
from django.contrib.auth.mixins import LoginRequiredMixin
from .models import PetOwner, Pet, Breed, Address


def signup(request):
    if request.method == "POST":
        form = UserCreationForm(request.POST)
        if form.is_valid():
            form.save()
            username = form.cleaned_data.get("username")
            password = form.cleaned_data.get("password1")
            user = authenticate(username=username, password=password)
            login(request, user)
            return redirect("/")
        else:
            return render(request, "signup.html", {"form": form})
    else:
        form = UserCreationForm()
        return render(request, "signup.html", {"form": form})

in urls.py

path("signup/", views.signup, name="signup"),

in signup.html

{% extends 'base.html' %}

<h1>Sign Up Page</h1>

{% block content %}
<form method="post">
  {% csrf_token %} {{ form.as_p }}
  <button type="submit">Register</button>
</form>
{% endblock content %}

Solution

You need save the related PetOwner after the user.

if form.is_valid():
    user = form.save()
    # Create the related data here...
    petOwner = PetOwner(
        user=user,
        first_name=user.first_name,
        last_name=user.last_name
    )
    petOwner.save()
    login(request, user)
    return redirect("/")
