node.js - 将函数数据添加到我的模型 - Node/Express

Question

我有一个包含输入字段“firstName”、“lastName”和“assetTag”的表单。我想提交该表单并发布所有数据以及一个名为“modelType”的附加字段。modelType 字段中的数据来自函数调用si.system()但我不确定如何将其传递给模型，因为它是一个承诺。

如何将数据从我的 console.log(data.model) 传递到我的 formData？

app.js 发布请求：

app.post('/', (req, res) => {

        si.system()
    .then(data => console.log(data.model))
    .catch(error => console.error(error))

  const formData = {
    firstName: req.body.firstName,
    lastName: req.body.lastName,
    assetTag: parseInt(req.body.assetTag)
  }

  const system = new System(formData);

  system.save()
    .then(result => {
      console.log(result);
    })
    .catch(err => {
      console.log(err);
    });

});

模型：

const mongoose = require('mongoose');

var SystemSchema = new mongoose.Schema({
    firstName: {
        type: String,
        required: true
    },
    lastName: {
        type: String,
        required: true
    },
    assetTag: {
        type: Number,
        required: true
    },
    modelType: {
        type: String,
        required: true
    }
});

module.exports = mongoose.model('System', SystemSchema);

如果您正在谈论从承诺中获得该价值，则需要研究async / await。

这是代码

app.post('/', async (req, res) => {

  let data = await si.system();

  const formData = {
    firstName: req.body.firstName,
    lastName: req.body.lastName,
    modelType: data.model,
    assetTag: parseInt(req.body.assetTag)
  }

  const system = new System(formData);

  system.save()
    .then(result => {
      console.log(result);
    })
    .catch(err => {
      console.log(err);
    });

});
