mongoose - Can a Mongo model self reference

Question

I have a model like this:

var userSchema = new mongoose.Schema({
  _id: { type: Schema.ObjectId },
  email: { type: String, unique: true },
  ipAddress: { type: String },
  referals: [{
    type: mongoose.Schema.Types.ObjectId, ref: 'User'
  }],
  redeem_token: {type: String, unique: true}
});

var User = mongoose.model('User', userSchema);

Can this work? The user, needs to have a reference to other users. It's to track signup referrals. I want to then use .Populate and expand the users in the referals[]

Answer 1

I'm using Mongoose. This works for me, I'm simply using this as a reference to the model. I have a Comment model. Comments can have a reply that is also Comment.

var Comment = new mongoose.Schema({
  id: { type: ObjectId, required: true },
  comment:    { type: String },
  replies:    [ this ],
});
