Question

我正在使用mongoDB和node.js尝试创建两个模型应用程序和 contactsapp 之间的关系

applicationsModel

'use strict'

const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const contactapp = mongoose.model('ContactApp');

const ApplicationsSchema = Schema({
  application_code: String,
  name: String,
  comments: String,
  version: String,
  developer: String,
  url: String,
  active: Boolean,
  press_package: String,
  pad_file: String,
  image: String,
  category: [String],
  contacts: [{ type: Schema.ObjectId, ref: "ContactApp" }]
});

module.exports = mongoose.model('Applications', ApplicationsSchema);

contactsappModel

'use strict'

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const ContactappSchema = Schema({
  fullname: String,
  avatar: String,
  company: String,
  jobTitle: String,
  email: String,
  phone: String,
  sex: String,
  country: String,
  channel: String,
  website_url: String,
  linkedin_url: String,
  xing_url: String,
  notes: String,
  active: Boolean
});

module.exports = mongoose.model('ContactApp',ContactappSchema);

但是当控制台给我错误时，Schema尚未注册模型“ContactApp”。

Answer 1

您的应用可能会在applicationsModel.js之前加载contactsappModel.js，因此执行此行时尚未注册ContactApp模型：

const contactapp = mongoose.model('ContactApp');

由于您还没有使用contactapp变量，请尝试完全删除该行。
