Using UUIDs in mongoose for ObjectID references

Question

I\'m building a CRUD-style REST service with Node.js, Express and MongoDB using mongoose. This service is going to allow users of an already existing android application to

You can still use populate() with _id values of types besides ObjectID, but you do need to use the same type in the reference definition.

So your trackPassSchema would need to change to:

var trackPassSchema = new Schema({
    _id: { type: String, default: function genUUID() {
        return uuid.v1()
    }},
    vehicle: [
        {type: String, required: true, ref: 'Vehicle'}
    ]
});

As Adam notes in the comments, you could simplify your default value to:

var trackPassSchema = new Schema({
    _id: { type: String, default: uuid.v1 },
    vehicle: [
        {type: String, required: true, ref: 'Vehicle'}
    ]
});
