heres a gist of where it was a few days ago along with comments that include the console from node and a find command from mongodb.
did you change something since then?
Jan 13 2018 00:29
Since then, we are now learning to reference and not embed the data, but when I try to link the data, nothing shows up. Though if I embed it, then there is no issue.
But embedding it is problmatic

if you want to add the schemas to the gist I'll take a peak.

@CodeME1118 in the version that is on this gist in the Comment.create callback you need to add ._id to comment so that it only pushes the id.

It seems that schema.indexes() doesn't include the default _id_ index?

Hello everyone I have a simple question about reference key
when let say you have a user table and you have a userProfile table
on you userProfile table you have a userId field, should this field be type of ObjectId as user._id or string?

That didn't work
weird part is it didn't even change the error that i was getting.

( UnhandledPromiseRejectionWarning: ValidationError: coffeshop validation failed: comments: Cast to [undefined] failed for value "[{"_id":"5a5981db5541e046aceddf05","comment":"Id occaecat laboris dolore commodo esse aliqua culpa enim incididunt tempor labore.","author":"Dolor","__v":0}]" at path "comments")

moreover I made a buffer comment and pushed it into coffeshop collection on my seed.js file may thats y ur seeing an id for your testdb on my db i could only view buffer comment not the one that i typed

@stherrienaspnet it should be an ObjectId ref. You can use populate or populateVirtual when retrieving data without extra effort.
Jan 13 2018 11:04
@sreekar2307 your seed.js is also trying to push the whole comment instance into the coffeeshop comments subdoc array. by adding ._id to the data.comments.push line, the behavior changed for me there too. I added a comment to your gist with my version of your seed.js and it's output.

that will never be an issue, because it will be triggered only once when we initially run the app when a user enters a comment
they will be directed to /coffeshops/:id which will render show.ejs.
moreover i completely changed schema of coffeshopSchema I directly embedded commentSchema without giving its reference inside it this is working fine.
I really appreciate your help. (updated)

hi, I am trying to update single nested sub document. Can you please take a look and tell me what I am doing wrong ?

bold Model

const mongoose = require('mongoose');

const PersonalInfoSchema = new mongoose.Schema({
  phoneNumber: String,
  gender: {
    type: String,
    enum: ['Male', 'Female', 'Other']
  dateOfBirth: Date

const UserSchema = new mongoose.Schema({
  personalInfo: {PersonalInfoSchema}
}, {timestamps: true});

UserSchema.methods.toPersonalInfoJson = function () {
  return {
    personalInfo: this.personalInfo.toJSON()

bold Server'/personalinfo', auth.required, function (req, res) {
    .exec(function (findErr, user) {
      if (findErr || !user) return res.status(401).json({findErr: 'User not found!'});

      if (typeof req.body.phoneNumber !== 'undefined') {
        user.personalInfo.phoneNumber = req.body.phoneNumber;
      if (typeof req.body.gender !== 'undefined') {
        user.personalInfo.gender = req.body.gender;
      if (typeof req.body.dateOfBirth !== 'undefined') {
        user.personalInfo.dateOfBirth = req.body.dateOfBirth;

      console.log(`updated user ${user}`); (err) {
        if (err) {
          console.log(`signup error ${err}`);
          return res.status(422).json({error: 'update failed!'});
        return res.json({user: user.toPersonalInfoJson()});

@gpulluri are you getting an error?
or getting a 401 from express?

the subdocument is not getting updated
no error
there are obvious issues in the above code. I think mongoose docs are immutable and new fields would not saved etc. I am just looking for an example of how to update nested sub docs
@lineus didnt tag you in the above messages

@lineus figure out the problem personalInfo: {PersonalInfoSchema} .. I shouldn't have wrapped the schema in curly braces
