GeddyJS, MongoDB, and Querying Subdocs? Try Mongoose

For the past few months I’ve been working on studying NodeJS. Currently, I’m trying to work with the GeddyJS Framework (geddyjs.org). Now they have a database agnostic ORM built into it that can support the likes of MySQL and PostgreSQL but also MongoDB and even flat files.

Unfortunately, there are some things that can’t work very well with the built in ORM (like MongoDB though it does have some functionality) and you might end up on your own there while some things aren’t supported. Now it’s still possible to use a different ORM so don’t npm remove yet!

For example, you have a schema that looks like this:

var Deck = function () {

    title: {type: 'string', required: true},
    cards: {type: 'object', objectProp: [{name: 'string', type: 'string', id: 'string'}]}


Now let’s say you wanted to find all Decks that had a certain card name in it. You can’t use the built in Geddy Model ORM for that yet.

Come in MongooseJS (mongoosejs.com). Actually you can use any other ORM for that matter but for simplicity’s sake let’s use Mongoose. Read more
