我正在尝试构建注释模型包含:Reply和CommentThread.CommentThread包含Reply,而Reply可以自行递归.

/models/comment.js:

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

var replySchema = new Schema({
  username: String,
  timestamp: { type: Date, default: Date.now },
  body: String,
  replies: [replySchema]
}, {_id: true});

var commentThreadSchema = new Schema({
  title: String,
  replies: [replySchema]
});

var Reply = mongoose.model('Reply', replySchema);
var CommentThread = mongoose.model('CommentThread', commentThreadSchema);

module.exports = {
    Reply: Reply,
    CommentThread: CommentThread
};

我的错误消息是:架构阵列路径'回复'的值无效.不能replySchema将自己用作值类型？还是其他一些原因？

我知道如何使用“选择顶部”来编写分页查询，但是我不知道如何使用行号来编写它。谁能告诉我？谢谢！
