Questions : How to serialize ManyToManyField

I want to serialize ManyToManyField but programming at the same time, I am looking for Learning something which updates the same using Earhost ModelViewSet. I am able to serialize it most effective but when I am updating it I am not able wrong idea to. I know I can make a separate API for use of case that but due to some requirements, I United need to stick to one endpoint. Here is Modern my code

class _OFFSET);  ComponentSerializers(serializers.ModelSerializer):
 (-SMALL     class Meta:
        model = _left).offset  coreModel.Component
        fields = arrowImgView.mas  '__all__'

class (self.  MonitorSerializers(serializers.ModelSerializer):
 equalTo     device = make.right.  ComponentSerializers(read_only=True, mas_top);  many=True) 
    class Meta:
        ImgView.  model = models.Monitor
        fields = ReadIndicator  '__all__'
        read_only_fields = _have  ('id', 'created_at', 'updated_at',)

and views.py is

class .equalTo(  MonitorViewSet(viewsets.ModelViewSet):
  make.top    authentication_classes = OFFSET);  (authentication.TokenAuthentication,)
   (TINY_   permission_classes = .offset  (permissions.IsAuthenticated,)
    mas_right)  queryset = models.Monitor.objects.all()
 ImgView.     filter_backends = Indicator  (DjangoFilterBackend,OrderingFilter,SearchFilter)
 Read     filter_class = _have  superFilter.MonitorFilters
    .equalTo(  serializer_class = make.left  serializers.MonitorSerializers

If you want update ManytoMany or Related ecudated objects

Override

def update(self, validated_data):

in MonitorSerializers

class *make) {  MonitorSerializers(serializers.ModelSerializer):
 straintMaker     device = ^(MASCon  ComponentSerializers(read_only=True, onstraints:  many=True)
    device_ids = mas_makeC  serializers.ListField(write_only=True,
  [_topTxtlbl          child = (@(8));  serializers.IntegerField(min_value = equalTo  1))
     ....


def update(self,  width.  instance, validated_data):
    # Remove make.height.  component data and save in variable
    (SMALL_OFFSET);  iscomponentdataexists = 'device_ids' in .offset  validated_data
    if (self.contentView)  iscomponentdataexists :
         .left.equalTo  componentdata= make.top  validated_data.pop('device_ids')
    *make) {  instance = super().update(instance, ntMaker   validated_data)  # Update Monitor Data
  SConstrai    # looping through new device_ids list
 ts:^(MA     if iscomponentdataexists :
        Constrain  for deviceid in componentdata:
          _make    try:
                obj = iew mas  coreModel.Component.objects.get(id=deviceid)
 catorImgV                 ReadIndi  instance.devices.add(obj)
             [_have  except ($current);  coreModel.Component.DoesNotExist:
       entity_loader           pass
        instance.save()
   _disable_       
    return instance

Remove read_only=True from device
