Question

我正在尝试使用最新的mongoose doc中所述的insertMany：

test.utility.js

import mongoose from 'mongoose';
import Groups from '../models/group.model';

const utils = {
  createMultipleGroups(n) {
    if (n > 26) {
      console.log('Cannot create more than 26 groups');
      return false;
    }
    const letters = 'ABCDEFGHJIKLMNOPQRSTUVWXYZ';
    const multiGroups = [];
    for (let i = 0; i < n; i += 1) {
      multiGroups.push({ name: `Group${letters.charAt(i)}`, description: `Description Group${letters.charAt(i)}` });
    }
    console.log('UTILITY multiGroups array: %j', multiGroups);

// UTILITY multiGroups array
// [{"name":"GroupA","description":"Description GroupA"}
//. {"name":"GroupB","description":"Description GroupB"},
// {"name":"GroupC","description":"Description GroupC"}]

    console.log(mongoose.connection.readyState); // 2 connecting !

    Groups.insertMany(multiGroups)
      .then((savedGroups) => {
        console.log('saved multi groups: ', savedGroups.length);
        return savedGroups;
      })
      .catch((e) => {
        console.log('error saving multi groups %j', e);
        return [];
      });
  },

这个函数是从前钩子中的mocha测试中调用的

user.test.js

import mongoose from 'mongoose';
import request from 'supertest';
import httpStatus from 'http-status';
import chai, { expect } from 'chai';
import app from '../../../index';
import User from '../../models/user.model';
import utils from '../../helpers/tests.utility';

/**
 * root level hooks
 */
before(() => {
  const createdGroups = utils.createMultipleGroups(3);
  console.log('created groups: %j', createdGroups);  // undefined
});

但是它没有返回任何内容..并且在控制台中没有任何东西......来自test.utility控制台日志
在user.test控制台日志中返回时出现'undefined'

我哪里错了？

感谢您的反馈

mongoose 4 InsertMany返回undefined
