node.js - 如何显示来自 mongodb 的无限嵌套注释

Question

所以每条评论都是它自己的文档。当用户回复评论时，这就是我将评论嵌套在一起的方式吗？如果嵌套了某些内容(假设回复深度达到 10 个)，我该如何执行 for 循环来遍历所有内容？

var RK = mongoose.Schema.ObjectId;
var CommentSchema = Schema({
    body: {type: String},
    chapterId: {type: RK, ref: 'Chapter'},
    by: {type: RK, ref: 'User'},
    children: [{
        type: RK,
        ref: 'Comment'

     }]
}, {timestamps: true});

Answer 1

let dependencySchema = mongoose.Schema({
    dependencyComment: {
        type: mongoose.Schema.Types.ObjectId,
        required: false
    },
    dependencyAuthor: {
        type: mongoose.Schema.Types.ObjectId,
        required: false
    }
});

let CommentSchema = mongoose.Schema({
    //Rest of you schema
    children: [{
        type: mongoose.Schema.Types.ObjectId,
        ref: [dependencySchema]

     }]
}, {timestamps: true});

这样你就可以将评论嵌套到第 N 层
