Referencing documents

[silently]

Hello, this is more a question than an issue:
what "type" should be set when we want to reference another doc within a Schema?

I've tried:

schema: {
  userId: {
    type: Meteor.Collection.ObjectID
  }
}

But got a failed validation.

Thanks!

If your intent is to store a link to a doc in Meteor.users, I think it uses String _id by default.

The more general answer to your question is: you're doing it correctly. If userId is an instance of Meteor.Collection.ObjectID, it should not fail validation.

Ok you were right: with a type String it works. I guess IDs are populated as Meteor.Collection.ObjectID but are stored as String in mongo.

Thank you!

For anyone else who lands here it looks like SimpleSchema.RegEx.Id is the way to acomplish this now with stricter validation than just String

if you want to use Mongo.Collection.ObjectID then you always need to specify blackbox: true

_id: { type: Mongo.Collection.ObjectID, blackbox: true },
