使用rest框架模型序列化程序更新django ManytoMany关系

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):
    class Meta:
        model = User
        fields = '__all__'

class GroupSerializer(serializers.ModelSerializer):
    class Meta:
        model = Group
        fields = '__all__'

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

class UserUpdateView(generics.UpdateAPIView):
    queryset = User.objects.all()
    serializer_class = UserSerializer

    def update(self, request, *args, **kwargs):
        instance = self.get_object()
        group_ids = request.data.get('groups', [])
        instance.groups.set(group_ids)
        instance.save()
        return self.partial_update(request, *args, **kwargs)

from django.urls import path
from .views import UserUpdateView

urlpatterns = [
    path('users/<int:pk>/', UserUpdateView.as_view(), name='user-update'),
]
