问如何使用我在restapi中定义的方法查看属于我的模型的字段的值？

EN

     ## Serializer.py ##
            
    class AdvertiseMainSerializer(ModelSerializer):
        class Meta:
            model = Advertise
            fields = '__all__'



     ## views.py##

    class advertise(ListAPIView):
        serializer_class = AdvertiseMainSerializer
        queryset = Advertise.objects.all()

   ## model.py##



    class Advertise(models.Model):
        owner = models.ForeignKey(to="user.User", on_delete=models.CASCADE, null=True)
        title = models.CharField(max_length=100, verbose_name="ilan başlığı")
        frontal = models.ManyToManyField(to="advertise.Frontal")
