Question

假设我有两个mongoose模式：

var AccountSchema = new Schema({ 
       userName: String
     , password: String
})
var AgentSchema = new Schema({
     Name : String
   , Account: AccountSchema
})

无论如何都要将AccountSchema添加到AgentSchema而不是集合吗？

看起来不太可能。这两种解决方案要么使用DocumentId，要么使用虚拟：

<强>的ObjectId：

var mongoose = require('mongoose')
  , Schema = mongoose.Schema
  , ObjectId = Schema.ObjectId;

var AccountSchema = new Schema({ 
       userName: String
     , password: String
})
var AgentSchema = new Schema({
     name : String
   , account: {type: ObjectId}
})

<强> VIRTUALS：

var AccountSchema = new Schema({ 
       userName: String
     , password: String
})
var AgentSchema = new Schema({
     name : String
   , _accounts: [AccountSchema]
})

AgentSchema.virtual('account') 
   .set(function(account) { this._accounts[0] = account; }) 
   .get(function() { return this._accounts.first(); });

如何在Mongoose中为现有模式定义嵌套对象？
