如何在Django restful响应中为双方显示不对称的多对多自我关系？

from django.db import models

class User(models.Model):
    name = models.CharField(max_length=100)
    friends = models.ManyToManyField('self', blank=True, symmetrical=False)

from rest_framework import serializers

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ['id', 'name', 'friends']

from rest_framework import generics

class UserListView(generics.ListAPIView):
    queryset = User.objects.all()
    serializer_class = UserSerializer

from django.urls import path

urlpatterns = [
    path('users/', UserListView.as_view(), name='user-list'),
]
