Mongoose complex (async) virtuals

Question

I have two mongoose schemas as follow:

var playerSchema = new mongoose.Schema({
    name: String,
    team_id: mongoose.Schema.Types.ObjectI         


        

Answer 1

This is probably best handled as an instance method you add to teamSchema so that the caller can provide a callback to receive the async result:

teamSchema.methods.getSquad = function(callback) {
  Players.find({ team_id: this._id }, callback);
});
