如何使用mongoose，nodeJs ( Express )在数据库中插入多个同名字段数据

npm install mongoose

const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/mydatabase', { useNewUrlParser: true, useUnifiedTopology: true });

const Schema = mongoose.Schema;

const myDataSchema = new Schema({
  fieldName: String
});

const MyData = mongoose.model('MyData', myDataSchema);

const data1 = new MyData({ fieldName: 'Data 1' });
const data2 = new MyData({ fieldName: 'Data 2' });
const data3 = new MyData({ fieldName: 'Data 3' });

MyData.insertMany([data1, data2, data3], function(err) {
  if (err) {
    console.error(err);
  } else {
    console.log('Multiple data inserted successfully.');
  }
});
