Django RestframeWork串行器关系，如何获取一对一模型的数据？

from rest_framework import serializers
from .models import User, Profile

class ProfileSerializer(serializers.ModelSerializer):
    class Meta:
        model = Profile
        fields = '__all__'

class UserSerializer(serializers.ModelSerializer):
    profile = ProfileSerializer()  # 嵌套使用ProfileSerializer

    class Meta:
        model = User
        fields = '__all__'

from rest_framework import viewsets
from .serializers import UserSerializer
from .models import User

class UserViewSet(viewsets.ModelViewSet):
    queryset = User.objects.all()
    serializer_class = UserSerializer
