Django REST Framework，保存到自定义用户模型的其他字段

Question

使用Django REST Framework（DRF），我添加了一个带有一个额外字段的自定义用户模型。 我已将代码发布在底部。

现在，当使用DRF的图形界面注册新用户（'/ rest-auth / registration /'）时，我确实获得了新模型字段的额外输入。 当我在此表单输入中输入值并单击POST时，确实创建了一个新用户，但多余的字段保持为空。

我一直在研究如何使其正常工作，并找到了另一个具有良好示例和答案的SO问题，但是此SO帖子的问题在于张贴者使用AbstractBaseUser作为其自定义用户模型所继承的类，而我想要改为使用AbstractUser。 （为什么？由于我读过建议这样做，除非您真正了解自己在做什么。）

由于其他SO答案中的发布者使用AbstractBaseUser，因此他的解决方案似乎涉及比我需要更多的代码和编译。

因此，有人可以告诉我有关在注册正确的数据时如何在注册过程中填写额外字段的建议吗？

users.models.py：

from django.contrib.auth.models import AbstractUser
from django.db import models


class CustomUser(AbstractUser):
    preferred_locale = models.CharField(max_length=2,
                                        blank=True,
                                        null=True)

user.serializers.py：

from rest_framework import serializers

from allauth.account.adapter import get_adapter
from allauth.account.utils import setup_user_email

from rest_auth.registration.serializers import RegisterSerializer


class CustomRegisterSerializer(RegisterSerializer):
    preferred_locale = serializers.CharField(
        required=False,
        max_length=2,
    )

    def get_cleaned_data(self):
        return {
            'preferred_locale': self.validated_data.get('preferred_locale', 'en'),
            'username': self.validated_data.get('username', ''),
            '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)
        user.preferred_locale = self.cleaned_data.get('preferred_locale')
        self.custom_signup(request, user)
        setup_user_email(request, user, [])
        return user

Answer 1

调用adapter.save_user() ，仅保存一组预定义的字段（ 此处为源代码）。 据我所知，保存用户后，不会再保存他。 因此，这应该工作：

def save(self, request):
    adapter = get_adapter()
    user = adapter.new_user(request)
    user = adapter.save_user(request, user, self, commit=False)
    user.preferred_locale = self.validated_data.get('preferred_locale', 'en')
    user.save()
    self.custom_signup(request, user)
    setup_user_email(request, user, [])
    return user
