Mongoose: using the Model.create() method and new Model() constructor seem to ignore parameters

Question

I am trying to save a new document to a collection, but rather than taking the parameters from the Model() constructor or Model.create() method, an empty object is created. I am probably doing something wrong or missing a small detail somewhere but I am currently stuck. My mongoDB database is hosted locally on mongodb for windows.

I have a schema and model:

import mongoose from 'mongoose';

const CardSchema = new mongoose.Schema({
    sideA: String,
    sideB: String,
}) 

export const CardSetSchema = new mongoose.Schema({
    user_email: String,
    name: String,
    cards: [CardSchema],
});

const CardSet = mongoose.model('CardSet', CardSchema);

export default CardSet

I have an endpoint trying to make a new document:

    .post(async (req, res) => {
        const obj = { user_email: req.user_email, name: req.body.name, cards: [] };
        const cardSet = new CardSet(obj);
        await cardSet.save();
        res.status(201).json(cardSet);
    })

When looking at the data with console.log the object and cardSet look the following:

{ user_email: 'example-email@gmail.com', name: 'wa', cards: [] }
{ _id: new ObjectId("62481f4964d4b1789c3110c3") }

My connection URL looks like this: mongodb://localhost:27017/flash-card-test

When I check MongoDB Compass the collection is indeed being populated with empty objects.

Does anyone have any idea what could be going wrong here? Many thanks!

Answer 1

It was a mistake. I built a model from the CardSchema rather than the CardSet schema.
