Question

我试图弄清楚为什么我的架构数组引用会为数组行mongoose.Schema.Types.ObjectId引发错误。我试图用这个数组引用我的第二个集合模型，但我得到了Cannot read property Types of undefined

这是我的错误：

imagesModel.js:10
    description_id: { type: mongoose.Scehma.Types.ObjectId, ref: 'Description'}
                                           ^
TypeError: Cannot read property 'Types' of undefined

以下是模型：

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

var descriptionSchema = new Schema({
    pattern: String,
    color: String,
    body: String,
    images: [{type: mongoose.Schema.Types.ObjectId, ref: 'Images'}]
});

var Description = mongoose.model('Description', descriptionSchema);

module.exports = Description;

以下是作为参考的图像模型：

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

var imageSchema = new Schema({
    pattern: String,
    color: String,
    imageName: String,
    imageUrl: String,
    imageSource: String,
    description_id: { type: mongoose.Scehma.Types.ObjectId, ref: 'Description'}
});

imageSchema.pre('save', function(next){
    var Description = require("../models/descriptionModel");
    var image = this;
    Description.findOneAndUpdate({
        _id: {$in: {image.description_id}},
        {$push: {images: image._id}},
        next
    });
});

var Images = mongoose.model('Images', imageSchema);

module.exports = Images;

Mongoose Schema类型投掷错误
