django rest框架中具有多对多字段关系的CRUD操作

from django.db import models

class User(models.Model):
    name = models.CharField(max_length=100)
    groups = models.ManyToManyField('Group')

class Group(models.Model):
    name = models.CharField(max_length=100)

from rest_framework import serializers
from .models import User, Group

class UserSerializer(serializers.ModelSerializer):
    groups = serializers.PrimaryKeyRelatedField(queryset=Group.objects.all(), many=True)

    class Meta:
        model = User
        fields = ['id', 'name', 'groups']

class GroupSerializer(serializers.ModelSerializer):
    class Meta:
        model = Group
        fields = ['id', 'name']

from rest_framework import generics
from .models import User, Group
from .serializers import UserSerializer, GroupSerializer

class UserListCreateView(generics.ListCreateAPIView):
    queryset = User.objects.all()
    serializer_class = UserSerializer

    queryset = Group.objects.all()
    serializer_class = GroupSerializer

from django.urls import path
