Question

因此我在var array上添加新章节时遇到问题，我将如何执行此操作：

array.push({
            chapter: [
                {
                    id: 2,
                    title: 'adsf',
                    content: '',
                    authorNotes: 'asdf'
                }
            ]
        });

RiTest.ts

import * as mongoose from 'mongoose';

const Scheme = mongoose.Schema;

export const RiTestScheme = new Scheme({
    novelName: String,
    novelAuthor: String,
    novelCoverArt: String,
    novelTags: Array,
    chapters: [
        {
            id: Number,
            title: String,
            content: String,
            authorNotes: String
        }
    ]
});

export class RiTestController {
    public addChapter(callback: (data) => void) {
        var chapterInfoModel = mongoose.model('ChaptersTest', RiTestScheme);

        var array = [
        {
            chapter: [
                {
                    id: 0,
                    title: 'prolog',
                    content: 'conetntt is empty',
                    authorNotes: 'nothing is said by author'
                },
                {
                    id: 1,
                    title: 'making a sword',
                    content: 'mine craft end chapter',
                    authorNotes: 'nothing'
                }
            ]
        }
    ];

        let newChapterInfo = new chapterInfoModel(array);

        newChapterInfo.save((err, book) => {
            if (err) {
                return callback(err);
            } else if (!err) {
                return callback(book);
            }
        });
    }
}

这不起作用，var array未保存到let newChapterInfo = new chapterInfoModel(array);中，我正在尝试将另一章添加到array.chapter中，但数组未在chapterInfoModel()我将如何修复此数组并向该数组中添加一个项目，以在此现有集合中创建一个新条目

感谢您抽出宝贵时间回答我的问题。

您正在尝试将文档数组插入到您的收藏夹中，这就是它没有插入到您的收藏夹中的原因。

Document.prototype.save()将仅向您的收藏夹插入一个文档，具体取决于您的定义。因此，在下面的代码中插入chapter，

//array as Object
var array = {
    chapter: [
        {
            id: 0,
            title: 'prolog',
            content: 'conetntt is empty',
            authorNotes: 'nothing is said by author'
        },
        {
            id: 1,
            title: 'making a sword',
            content: 'mine craft end chapter',
            authorNotes: 'nothing'
        }
    ]
};

//Push to your chapter array
array.chapter.push({
    id: 2,
    title: 'adsf',
    content: '',
    authorNotes: 'asdf'
});

let newChapterInfo = new chapterInfoModel(array);

Mongodb-创建现有集合字段数组的条目
