How to save data to multiple models with one form? - django

Question

a pretty noob here. I am trying to create a user profile at the time when the account is created using signals. I want all the fields of the user profile to be filled in sign up page.
This is the user profile that I am trying to populate:
class UserProfile(models.Model):
user = models.ForeignKey(get_user_model(), verbose_name='user', on_delete=models.CASCADE)
name = models.CharField(max_length=255, null=True)
contact_number = models.CharField(max_length=11, default="0331232132")
def __str__(self):
return self.name
This is my custom user model here:
class CustomUserManager(BaseUserManager):
def _create_user(self, email, password, **kwargs):
if not email:
raise ValueError("The given email must be set")
email = self.normalize_email(email)
user = self.model(email=email, **kwargs)
user.set_password(password)
user.save(using=self._db)
return user
def create_user(self, email, password=None, **kwargs):
kwargs.setdefault("is_staff", False)
kwargs.setdefault("is_superuser", False)
return self._create_user(email, password, **kwargs)
def create_superuser(self, email, password=None, **kwargs):
kwargs.setdefault("is_staff", True)
kwargs.setdefault("is_superuser", True)
if kwargs.get('is_staff') is not True:
raise ValueError('Superuser must have is_staff=True.')
if kwargs.get('is_superuser') is not True:
raise ValueError('Superuser must have is_superuser=True.')
return self._create_user(email, password, **kwargs)
class User(AbstractUser):
username = None
email = models.EmailField(_("email address"), unique=True)
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = []
objects = CustomUserManager()
This is my user creation form that I am sending to template:
class CustomUserCreationForm(UserCreationForm):
password2 = forms.CharField(
label=_("Confirm Password"),
widget=forms.PasswordInput,
)
name = forms.CharField()
contact_number = forms.CharField(
max_length=11
)
class Meta:
model = get_user_model()
fields = ['email']
I am not sure if it is relevant but this is my custom email backend.
class EmailBackend(ModelBackend):
def authenticate(self, request, username=None, password=None, **kwargs):
try:
user = User.objects.get(email__iexact=username)
except User.DoesNotExist:
return None
except User.MultipleObjectsReturned:
return User.objects.filter(email=username).order_by('id').first()
else:
if user.check_password(password) and self.user_can_authenticate(user):
return user
def get_user(self, user_id):
try:
user = User.objects.get(pk=user_id)
except User.DoesNotExist:
return None
return user if self.user_can_authenticate(user) else None
Now what I want is when the user submits the user creation form, Email and Password field is used to create a user account while name and contact number along with the newly created user object are used to create a userprofile instance using signals. All the examples that I have seen till now only handle setting only the user object in profile.
