嵌入模式给出错误

我试图将模式嵌入到我创建的其他模式中，但我不断收到此错误：

我不完全确定这里出了什么问题，但我想要做的是将我的事件模式和兴趣模式的引用存储在用户模式内。如果有人能告诉我我做错了什么，那就太好了，谢谢！

编辑：我现在收到一个新错误：

我的用户架构

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);

我的活动架构

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);

我的兴趣架构

var mongoose = require('mongoose');

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

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

这是因为您在模块中导出的内容不是Schemas， 他们是Models。当你这样做时var EventSchema = require('../Models/Event');你需要Event Model，不是Event Schema。要从模型访问底层架构，您可以执行以下操作：

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

当您引用属于另一个集合的文档时，您还会遇到问题，这应该有效：

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);

兴趣模型：

var mongoose = require('mongoose');

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

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

用户型号：

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);
