无法通过DRF和Djoser的配置文件模型保存扩展Django用户的配置文件数据

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

class UserProfile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    # 添加其他配置文件字段
    bio = models.TextField()
    avatar = models.ImageField(upload_to='avatars/')

from django.db.models.signals import post_save
from django.dispatch import receiver
from django.contrib.auth.models import User
from .models import UserProfile

@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
    if created:
        UserProfile.objects.create(user=instance)

@receiver(post_save, sender=User)
def save_user_profile(sender, instance, **kwargs):
    instance.userprofile.save()

AUTH_USER_MODEL = 'your_app.UserProfile'

from rest_framework import viewsets
from .models import UserProfile
from .serializers import UserProfileSerializer

class UserProfileViewSet(viewsets.ModelViewSet):
    queryset = UserProfile.objects.all()
    serializer_class = UserProfileSerializer

from rest_framework import serializers
from .models import UserProfile

class UserProfileSerializer(serializers.ModelSerializer):
    class Meta:
        model = UserProfile
        fields = '__all__'
