Mongoose在嵌入架構時分開文檔？

Question

我想在用戶創建一個新文檔後將文檔_id保存到另一個模式的數組中。簡而言之：用戶保存視頻URL，並且我想將視頻的文檔_id保存到用戶架構中的數組中。我無法弄清楚如何做到這一點。這裏是我的模型文件：

videos.js：

// Video Model 
// ------------- 

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

// Embedded document schema 
var NotesSchema = new Schema({ 
    timecode : String, 
    text  : String 
}); 

// Main schema 
var VideoSchema = new Schema({ 
    title : String, 
    url_id : String, 
    notes : [NotesSchema] 
}); 

module.exports = mongoose.model('Note', NotesSchema); 
module.exports = mongoose.model('Video', VideoSchema); 

account.js：

// Account Model 
// ------------- 

var mongoose = require('mongoose'); 
var Schema = mongoose.Schema; 
var Video = require('../models/videos.js'); 
var passportLocalMongoose = require('../node_modules/passport-local-mongoose/lib/passport-local-mongoose.js'); 

var AccountSchema = new Schema({ 
    username: String, 
    salt: { type: String, required: true }, 
    hash: { type: String, required: true }, 
    videos: [VideoSchema] // <- need to save here 
}); 

AccountSchema.plugin(passportLocalMongoose); 

module.exports = mongoose.model('Account', AccountSchema); 

這是我現在怎麼有代碼的設置來創建文檔並保存到MongoDB的。

var video = new Video({ 
    title : req.body.title, 
    url_id : req.body.url_id 
}); 

video.save(function(err) { 
    if (err) { 
     console.log(err); 
    } else { 
     res.redirect('videos/' + video._id); 
     console.log('video saved.'); 
     console.log('video information: ' + video); 
    } 
}); 

基本上，我不知道如何保存視頻和只發送視頻文檔_id到帳戶架構的陣列。我該怎麼做呢？

編輯：

儘管執行建議的修復，data._id不保存到帳戶架構內的陣列。沒有錯誤被拋出。當我使用mongo CLI檢查帳戶時，該數組爲空。

這裏是我的電流變化：

的Video.js

// Video Model 
// ------------- 

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

var NotesSchema = new Schema({ 
    timecode : String, 
    text  : String 
}); 

var VideoSchema = new Schema({ 
    title : String, 
    url_id : String, 
    notes : [NotesSchema] 
}); 

module.exports = mongoose.model('Note', NotesSchema); 
module.exports = mongoose.model('Video', VideoSchema); 

account.js

// Account Model 
// ------------- 

var mongoose = require('mongoose'); 
var Schema = mongoose.Schema; 
var Video = require('../models/videos'); 
var passportLocalMongoose = require('../node_modules/passport-local-mongoose/lib/passport-local-mongoose.js'); 

var AccountSchema = new Schema({ 
    nickname: String, 
    birthday: Date, 
    videos: [{ type: Schema.Types.ObjectId, ref: 'Video' }] 
}); 

AccountSchema.plugin(passportLocalMongoose); 

module.exports = mongoose.model('Account', AccountSchema); 

視頻route.js

var util = require('util'); 
var mongoose = require('mongoose'); 
var Video = require('../models/videos'); 
var Account = require('../models/account'); 

var video = new Video({ 
    title : req.body.title, 
    url_id : goodVimeoId 
}); 

video.save(function(err, data) { 
    if (err) { 
    console.log(err); 
    } else { 
    Account.findOne({username : req.user.username}, function(err, result) { 
     result.videos.push(video._id); 
     res.redirect('videos/' + video._id); 
    }); 

    } 
}); 

爲什麼任何建議視頻數據未保存到賬戶？再次感謝。

Answer 1

問題解決了：

我需要result.videos.push(video._id);後添加result.save();，像這樣：

Account.findOne({username : req.user.username}, function(err, result) { 
     result.videos.push(video._id); 
     result.save(); 
     res.redirect('videos/' + video._id); 
    }); 

Answer 2

剛剛注意到關於ObjectId的評論。已經更新了答案的要求：

var ObjectId = Schema.ObjectId; 

    var AccountSchema = new Schema({ 
     username: String, 
     salt: { type: String, required: true }, 
     hash: { type: String, required: true }, 
     videos: [{type: ObjectId, ref: 'Video'}] // <- need to save here 
    }); 
.... 
.... 

    video.save(function(err, data) { 
    Account.findOne({username:req.body.username}, function(err, result) { 
     result.videos.push(data._id); 
    }); 
    });
