嵌入模式是给错误

Question

我想，我已经创造了其他模式嵌入模式，我不断收到此错误：

我不能完全确定是怎么回事错在这里，但我想要做什么是存储用户架构内的事件架构和兴趣架构的引用。如果有人能告诉我我做错了什么，那将是非常感谢！

编辑：我现在接收新的错误：

我的用户模式

var mongoose = require('mongoose'); 
var EventSchema = require('../Models/Event').schema; 
var InterestSchema = require('../Models/Interest').schema; 

var UserSchema = new mongoose.Schema({ 
    email: String, 
    password: String, 
    eventsHosted: [EventSchema], 
    eventsAttended: [EventSchema], 
    currentlyAttending: [EventSchema], 
    currentlyHosting: [EventSchema], 
    profileImage: String, 
    interests: [InterestSchema], 
    followers: [UserSchema], 
    following: [UserSchema] 

}); 

module.exports = mongoose.model('User', UserSchema); 

我的事件模式

var mongoose = require('mongoose'); 
var UserSchema = require('../Models/User').schema; 

var EventSchema = new mongoose.Schema({ 
    title: String, 
    description: String, 
    location: String, 
    attendees: [UserSchema], 
    date: String, 
}); 

module.exports = mongoose.model('Event', EventSchema); 

个我的兴趣模式

var mongoose = require('mongoose'); 

var InterestSchema = new mongoose.Schema({ 
    name: String 
}); 

module.exports = mongoose.model('Interest', InterestSchema);

，那是因为你导出你的模块不Schemas，他们是Models。当你做var EventSchema = require('../Models/Event');你需要Event Model，而不是Event Schema。为了从模型访问底层架构，你可以这样做：

var EventSchema = require('../Models/Event').schema; 
var InterestSchema = require('../Models/Interest').schema; 
var UserSchema = require('../Models/User').schema; 

您也可以当你引用属于另一个集合文档的问题，这应该工作：

事件模型：

var mongoose = require('mongoose'); 
var UserSchema = require('./User').schema; 

var EventSchema = new mongoose.Schema({ 
    title: String, 
    description: String, 
    location: String, 
    attendees: [{ type: Schema.Types.ObjectId, ref: 'User' }], 
    date: String 
}); 

module.exports = mongoose.model('Event', EventSchema); 

利息型号：

var mongoose = require('mongoose'); 

var InterestSchema = new mongoose.Schema({ 
    name: String 
}); 

module.exports = mongoose.model('Interest', InterestSchema); 

用户模型：

var mongoose = require('mongoose'); 
var EventSchema = require('./Event').schema; 
var InterestSchema = require('./Interest').schema; 

var UserSchema = new mongoose.Schema({ 
    email: String, 
    password: String, 
    eventsHosted: [{ type: Schema.Types.ObjectId, ref: 'Event' }], 
    eventsAttended: [{ type: Schema.Types.ObjectId, ref: 'Event' }], 
    currentlyAttending: [{ type: Schema.Types.ObjectId, ref: 'Event' }], 
    currentlyHosting: [{ type: Schema.Types.ObjectId, ref: 'Event' }], 
    profileImage: String, 
    interests: [{ type: Schema.Types.ObjectId, ref: 'Interest' }], 
    followers: [{ type: Schema.Types.ObjectId, ref: 'User' }], 
    following: [{ type: Schema.Types.ObjectId, ref: 'User' }] 
}); 

module.exports = mongoose.model('User', UserSchema);
