发票存储库类

async addInvoice(invoice) {

    try {

        const Job = await this.getJobs();
        if (Job.jobStatus == "Completed") {

        invoice.invoiceNo = uuid.v4();

        invoice.invoiceDate = Date.now();

        invoice.oliveQuantity = Job.oliveQuantity;


        if (Job.productCategory == "Container") {

           let datas = await this.getData();


            invoice.ContainerType =Job.ContainerType

            //datas.filter(data => data.container.find(c => c.includes(invoice.ContainerType );


            invoice.containerAmount = Job.containerAmount;
            invoice.containerType = Job.containerType;


      }
        invoice.push(invoice);

        return await this.saveInvoice(invoice);
    }

} catch (err) {
    console.log(err);
    }

}

在方法 addInvoice（invoice）中，我需要知道客户使用哪种类型的集装箱，然后提取价格。然后取集装箱价格，乘以集装箱数量。容器数量应从Job Jason文件中提取

Answer 1

如果Container数组中对象的顺序始终相同并且已知，则只需执行Container[1]

否则，您必须根据要选择Container数组中元素之一的条件来更具体

问题更新后

invoice.ContainerObjectFromData = datas.container.find(c => c.ContainerType === invoice.ContainerType); 假设可以直接在getData调用返回的datas对象中找到datas.container。

读取JSON文件并提取数据
