嵌入架构给错误

Question

我试图将架构嵌入到我创建的其他架构中，并且不断出现此错误：

我不完全确定这里出了什么问题，但是我想做的是在用户模式中存储对我的事件模式和兴趣模式的引用。如果有人可以告诉我我在做什么错，那将非常感谢！

编辑：我现在收到一个新的错误：

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);

我的兴趣模式

var mongoose = require('mongoose');

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

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

Answer 1

这是因为您在模块中导出的不是Schemas，而是Models。在执行操作时，var EventSchema = require('../Models/Event');您需要的Event Model不是Event Schema。要从模型访问基础架构，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，您也会遇到问题，这应该可行：

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);

兴趣模式：

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);

如何在我的Mongoose模式中引用另一个模式？ http://mongoosejs.com/docs/populate.html
