如何在mongoose中保存/更新多个单据

const mongoose = require('mongoose');

const billSchema = new mongoose.Schema({
  title: String,
  content: String
});

const Bill = mongoose.model('Bill', billSchema);

const bills = [
  { title: 'Bill 1', content: 'Content 1' },
  { title: 'Bill 2', content: 'Content 2' },
  { title: 'Bill 3', content: 'Content 3' }
];

Bill.create(bills, (err, savedBills) => {
  if (err) {
    console.error(err);
  } else {
    console.log('Bills saved successfully:', savedBills);
  }
});

const filter = { title: 'Bill 1' };
const update = { content: 'New Content' };

Bill.updateMany(filter, update, (err, result) => {
  if (err) {
    console.error(err);
  } else {
    console.log('Bills updated successfully:', result);
  }
});
