findOneAndUpdate不更新字段名称

Question

字段名称不变。为什么呢？ ................................................... ................................................... ................................................... ................................................... ................................................... ................................................... ........................

router.post('/bio/firstname', (req, res) => {

  Habalka.findOneAndUpdate(
    {_id: "d9aa8566-75fe-4108-a72e-1b67e79cf40c"},
    {name: 5}
  )
    .then((data) => {
      res.json({error: false, data: data})
    });

});

模型

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const HabalkaSchema = new Schema({
  _id: {
    type: String
  },
  bio: {
    firstname: {},
    lastname: {},
    middlename: {},
    company: {}
  },
  rating: [

  ],
  files: [
    {

        type: String
      },
      destination: {
        type: String

      filename: {
        type: String
      },
      path: {
        type: String
      },
      folder: {

      },
      date: {
        type: Date,

});
module.exports = Habalka = mongoose.model('habalka', HabalkaSchema);

因此，假设路由运行正常，那么您的更新中只会出现语法错误，请尝试以下操作：

  Habalka.findOneAndUpdate(
    {_id: "d9aa8566-75fe-4108-a72e-1b67e79cf40c"},
    {$set: {name: 5}}
  )
    .then((data) => {
      res.json({error: false, data: data})
    });
