Custom User fields are fname, lname, email,username,password,phone ,gender,acctype. when I register user through the Django restframework, it only takes username,email and password and other field are become empty. what is the problem

my models.py file

from django.db import models
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager,User

# Create your models here.

GENDER_CHOICES = (
   ('M', 'Male'),
   ('F', 'Female')
)


class AccountManager(BaseUserManager):
    def create_user(self, email, username, phone, gender, password=None, **extrafields):
        if not email:
            raise ValueError("email is needed")
        if not username:
            raise ValueError("username is needed")
        if not phone:
            raise ValueError("Phone is needed")
        if not gender:
            raise ValueError("gender is needed")
        user= self.model(
            email=self.normalize_email(email),
            username=username,

Answer 1

Django-allauth doesn't allow saving custom fields by default

To solve this problem I refined a save function inside CustomRegisterSerializer and simply assign the custom field values. Then saved it using user.save()

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.fname=self.cleaned_data.get('fname')
        user.lname=self.cleaned_data.get('lname')
        user.phone=self.cleaned_data.get('phone')
        user.acctype=self.cleaned_data.get('acctype')
        user.gender=self.cleaned_data.get('gender')

        user.save()

        return user
