DRF -如何在中间模型中仅查询用户拥有的对象？

class UserObject(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    object = models.ForeignKey(Object, on_delete=models.CASCADE)

    @staticmethod
    def get_user_objects(user):
        return UserObject.objects.filter(user=user).values_list('object', flat=True)

class UserObjectSerializer(serializers.ModelSerializer):
    objects = serializers.SerializerMethodField()

    def get_objects(self, instance):
        user = self.context['request'].user
        user_objects = UserObject.get_user_objects(user)
        return user_objects

    class Meta:
        model = UserObject
        fields = ['objects']
