Question

我正在尝试创建一个较小的架构，以便可以在较大的架构中重复使用。.

我的“用户”模式已定义（在另一个文件中）

const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const noRights = require('../models/Roles').user_noRights;
const UserSchema = new Schema({
    // these are required to create a user
    name: {type: String, required: true},
    email: {type: String, required: true, lowercase: true},
    password: {type: String, required: true},
    role: {type: String, required: true, default: noRights},
})
module.exports = User = mongoose.model('users', UserSchema)

这有效（但未使用较小的“用户”模式）

const PostSchema = new Schema({
  text: {type: String, required: true },
  date: {type: Date,default: Date.now},
  user: { 
      type: Schema.Types.ObjectId, 
      ref: 'users'
  }
});

这是我要使用的较小的“用户”模式：

const userData = new Schema({
  type: Schema.Types.ObjectId, 
  ref: 'users' 
});

此处使用了较小的“用户”模式，但失败了：

const PostSchema = new Schema({
  text: {type: String, required: true },
  date: {type: Date,default: Date.now},
  user: { type: userData },
});

这是错误

C:\GitHub\node_modules\mongoose\lib\schema.js:717
[0]     throw new TypeError('Undefined type `' + name + '` at `' + path +
[0]     ^
[0]
[0] TypeError: Undefined type `Users` at `ref`
[0]   Did you try nesting Schemas? You can only nest using refs or arrays.

我使用npm的“ deepPopulate”模块解决了这个问题-非常好！

如何在较大的架构中使用具有引用的较小的架构？
