Node.js 我可以使用区段与nodejsmongoose创建一个子类吗？

我甚至还上过课。我想做的是使用构造函数。 我想创建一个子类

ex）

我的代码：

我创建了一个类并在模式上运行loadClass。但是我想让OrderLog成为一个结构，当我第一次调用这个类时，它使用构造函数返回子类

const { Schema } = require('mongoose');

const orderLogSchema = new Schema({
    userId: {type: String, required: false, index: true},
    orderPlanId: {type: String, required: false, index: true},
    orderId: {type: String, required: false, index: true},
    planType: {type: String, required: true, index: true},
    indicatorType: {type: String},
    bundle: {type: String},
    action: {type: String, required: true},
    orderContents: {type: String},
    createdAt: {type: Date, required: true},
});


class OrderLog {
    constructor(...args) {
    }

    static makeNew(orderLogForm){
        const saveOrderLogForm = {
            userId: orderLogForm.userId,
            orderPlanId: orderLogForm.orderPlanId,
            orderId: orderLogForm.id,
            planType: orderLogForm.planType,
            indicatorType: orderLogForm.indicatorType,
            bundle: orderLogForm.bundle,
            action: orderLogForm.action,
            orderContents: orderLogForm.orderContents,
            createdAt: orderLogForm.createdAt
        };
        const orderLog = new this(saveOrderLogForm)
        orderLog.save();
    }
}

orderLogSchema.loadClass(OrderLog);


module.exports = (connectionPool) => {
    let orderLogModel = connectionPool.model('OrderLog', orderLogSchema);
    return orderLogModel;
};

const { Schema } = require('mongoose');

const orderLogSchema = new Schema({
    userId: {type: String, required: false, index: true},
    orderPlanId: {type: String, required: false, index: true},
    orderId: {type: String, required: false, index: true},
    planType: {type: String, required: true, index: true},
    indicatorType: {type: String},
    bundle: {type: String},
    action: {type: String, required: true},
    orderContents: {type: String},
    createdAt: {type: Date, required: true},
});


class OrderLog {
    constructor(...args) {
    }

    static makeNew(orderLogForm){
        const saveOrderLogForm = {
            userId: orderLogForm.userId,
            orderPlanId: orderLogForm.orderPlanId,
            orderId: orderLogForm.id,
            planType: orderLogForm.planType,
            indicatorType: orderLogForm.indicatorType,
            bundle: orderLogForm.bundle,
            action: orderLogForm.action,
            orderContents: orderLogForm.orderContents,
            createdAt: orderLogForm.createdAt
        };
        const orderLog = new this(saveOrderLogForm)
        orderLog.save();
    }
}

orderLogSchema.loadClass(OrderLog);


module.exports = (connectionPool) => {
    let orderLogModel = connectionPool.model('OrderLog', orderLogSchema);
    return orderLogModel;
};
