Question 118421 in Mongodb Question posted in
The official documentation can be found here.

creating new field doesn't want to save mongoose.Types.ObjectId as a column in MongoDB

I am trying to link two tables in mongo db. I have a User table where user has an _id. And a News table where the columns should be _id(for the news) and the userId (to link news to a user).

The way my api works, is the userID gets appended to req variable when the request goes through authentication.

This is the model for User

const mongoose = require("mongoose");
const User = mongoose.model(
  "User",
  new mongoose.Schema({
    name: String,
    surname: String,
    email: String,
    password: String,
    admin: Boolean,
    profileImage: String,
  })
);

And this is a model for News

const mongoose = require("mongoose");
const News = mongoose.model(
  "News",
  new mongoose.Schema({
    userID: {
      type: mongoose.Schema.Types.ObjectId,
      ref: "User",
    },
  })
);

and this is the snippet for saving a new news record:

upload = (req, res) => {
const news = new News({
    userId: mongoose.Types.ObjectId(req.userId)
})

//at this point userID in news is UNDEFINED for some reason. req.userId is not undefined.
news.save((err)=>{
      if (err) {
        res.status(500).send({ message: err + "NewsError" });
        return;
      }

})
}

Ideally this should end with a new row appearing in the table in the database, but only the auto generated _id appears, and no userID
No UserID column

    I found the error:), Where I define the model. userID is spelled with capital ID, but where I assign the variable its written as userId. I am just blind. Thanks for everyones help.

    Maybe instead of mongoose.Types.ObjectId(req.userId) you can instead use this code:

    const { ObjectId } = require('mongodb');

userId: ObjectId(req.userId);
