在Mongoose中向多维对象数组添加项目

const mongoose = require('mongoose');

const projectSchema = new mongoose.Schema({
  name: String,
  tasks: [{
    name: String,
    status: String
  }]
});

const Project = mongoose.model('Project', projectSchema);

const project = new Project({
  name: 'My Project',
  tasks: []
});

project.tasks.push({ name: 'Task 1', status: 'Pending' });
project.tasks.push({ name: 'Task 2', status: 'Completed' });

project.save((err, savedProject) => {
  if (err) {
    console.error(err);
  } else {
    console.log(savedProject);
  }
});

Project.updateOne(
  { _id: projectId },
  { $push: { tasks: { name: 'Task 3', status: 'Pending' } } },
  (err, result) => {
    if (err) {
      console.error(err);
    } else {
      console.log(result);
    }
  }
);
