Invalid value for schema.

Question

I am trying to build a comment model that contains: Reply and CommentThread. CommentThread contains the response, and the response can overwrite itself.

/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 }; 

My error message: Invalid value for the Responses schema. Can't answer. Schema use myself as a value type? Or some other reasons?

see example above you need to do something like

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