使用mongoose将嵌入文档的多个实例保存到我的模型

const mongoose = require('mongoose');

const EmbeddedSchema = new mongoose.Schema({
  // 定义嵌入文档的字段
  field1: String,
  field2: Number,
  // ...
});

module.exports = mongoose.model('Embedded', EmbeddedSchema);

const mongoose = require('mongoose');
const Embedded = require('./embeddedModel'); // 引入嵌套模型

const MainSchema = new mongoose.Schema({
  // 定义主模型的字段
  fieldA: String,
  fieldB: Number,
  embeddedDocs: [Embedded.schema], // 嵌套文档数组
  // ...
});

module.exports = mongoose.model('Main', MainSchema);

const Main = require('./mainModel'); // 引入主模型

const mainInstance = new Main({
  fieldA: 'Value A',
  fieldB: 123,
  embeddedDocs: [
    { field1: 'Value 1', field2: 456 },
    { field1: 'Value 2', field2: 789 },
    // ...
  ],
});

mainInstance.save((err, savedMain) => {
  if (err) {
    console.error(err);
  } else {
    console.log('Main instance saved:', savedMain);
  }
});
