在快速路线(Mongoose、MongoDB、Express)中更新文档中的属性

const mongoose = require('mongoose');

const userSchema = new mongoose.Schema({
  name: String,
  age: Number,
  email: String
});

const User = mongoose.model('User', userSchema);

User.findOneAndUpdate({ name: 'John' }, { age: 30 }, { new: true })
  .then(updatedUser => {
    console.log(updatedUser);
  })
  .catch(error => {
    console.log(error);
  });

User.findOneAndUpdate({ name: 'John' }, { age: 30, email: 'john@example.com' }, { new: true })
  .then(updatedUser => {
    console.log(updatedUser);
  })
  .catch(error => {
    console.log(error);
  });

User.findOneAndUpdate({ name: 'John' }, { $set: { age: 30 } }, { new: true })
  .then(updatedUser => {
    console.log(updatedUser);
  })
  .catch(error => {
    console.log(error);
  });
