Django rest-auth allauth registration with email, first and last name, and without username

Question

I am using django-rest-auth and allauth for login and registration in my django app. I haven't written any extra single line of code of my own for login or registration. Registration is successful with emailid and provided password.

I am not using username for authentication, instead email.

In my browsable api for registration I get following:

Along with these fields I want to have first_name and last_name (the default auth_user table had these columns) so that my newly created auth_user also has these fields set along with email and hashed password.

How can I achieve this? This browsable form itself is not so important but being able to store first_name and last_name is what I need primarily.

1. Make sure you have ACCOUNT_USERNAME_REQUIRED = False in your settings.py file.

2. For first_name and last_name you need to write a custom RegisterSerializer (https://github.com/Tivix/django-rest-auth/blob/master/rest_auth/registration/serializers.py#L166)

here's a sample code for serializers.py

from allauth.account import app_settings as allauth_settings
from allauth.utils import email_address_exists
from allauth.account.adapter import get_adapter
from allauth.account.utils import setup_user_email

class RegisterSerializer(serializers.Serializer):
    email = serializers.EmailField(required=allauth_settings.EMAIL_REQUIRED)
    first_name = serializers.CharField(required=True, write_only=True)
    last_name = serializers.CharField(required=True, write_only=True)
    password1 = serializers.CharField(required=True, write_only=True)
    password2 = serializers.CharField(required=True, write_only=True)

    def validate_email(self, email):
        email = get_adapter().clean_email(email)
        if allauth_settings.UNIQUE_EMAIL:
            if email and email_address_exists(email):
                raise serializers.ValidationError(
                    _("A user is already registered with this e-mail address."))
        return email

    def validate_password1(self, password):
        return get_adapter().clean_password(password)

    def validate(self, data):
        if data['password1'] != data['password2']:
            raise serializers.ValidationError(
                _("The two password fields didn't match."))
        return data

    def get_cleaned_data(self):
        return {
            'first_name': self.validated_data.get('first_name', ''),
            'last_name': self.validated_data.get('last_name', ''),
            'password1': self.validated_data.get('password1', ''),
            'email': self.validated_data.get('email', ''),
        }

    def save(self, request):
        adapter = get_adapter()
        user = adapter.new_user(request)
        self.cleaned_data = self.get_cleaned_data()
        adapter.save_user(request, user, self)
        setup_user_email(request, user, [])
        user.profile.save()
        return user

3. In settings.py make sure you add to refer to new Serializer.

   REST_AUTH_REGISTER_SERIALIZERS = {
           'REGISTER_SERIALIZER': 'path.to.RegisterSerializer',
   }
