Python 如何在框架中获得所需的结果？

我有以下模型，希望在WebAPI中显示一些必需的结果

class Poll(models.Model):
    question = models.CharField(max_length=100)
    created_by = models.ForeignKey(User, on_delete=models.CASCADE)
    pub_date = models.DateTimeField(auto_now=True)

class Choice(models.Model):
    poll = models.ForeignKey(Poll, related_name='choices', on_delete=models.CASCADE)
    choice_text = models.CharField(max_length=100)

class Vote(models.Model):
    choice = models.ForeignKey(Choice, related_name='votes', on_delete=models.CASCADE)
    poll = models.ForeignKey(Poll, on_delete=models.CASCADE)
    voted_by = models.ForeignKey(User, on_delete=models.CASCADE)

我的设置方式如下所示：

class VoteSerializer(serializers.ModelSerializer):
    voted_by = serializers.StringRelatedField(many=False)

    class Meta:
        model = Vote
        fields = '__all__'
class ChoiceSerializer(serializers.ModelSerializer):
    votes = VoteSerializer(many=True, required=False)

    class Meta:
        model = Choice
        fields = '__all__'
class PollSerializer(serializers.ModelSerializer):
    choices = ChoiceSerializer(many=True, read_only=True, required=False)
    created_by = serializers.StringRelatedField(many=False) 
    class Meta:
        model = Poll
        fields = '__all__'

class UserSerializer(serializers.ModelSerializer):

    class Meta:
        model = User
        fields = ('username', 'email', 'password')
        extra_kwargs = {'password': {'write_only': True}}

    def create(self, validated_data):
        user = User(
            email=validated_data['email'],
            username=validated_data['username']
        )
        user.set_password(validated_data['password'])
        user.save()
        Token.objects.create(user=user)
        return user

我想要一个结果，其中只有那些投票显示在选项中，其中vote_by='choicse id'。 **但结果包括所有的选票**

{ “id”：1， “投票”：[ { “id”：1， “投票人”：1， "选择":一,， “投票”：1 }, { “id”：2， “投票人”：2， "选择":一,， “投票”：1 } ], “选择文本”：“它提供web API和安全认证权限。”， “投票”：1 }
