Create mongoose reference of models in differents files

I need to create references to 2 models which are in different files. My models are:

Profesor
Curso

I want Curso to have a reference to a Profesor. My problem is that when the models Curso is being created, the model Profesor does not exist yet.

MissingSchemaError Schema hasn't been registered for model Profesor

If the reference is to the model Alumno there isn´t problem because Alumno is created before Curso right?

Just create all your schemas first and then register your models. And do all of this when you bootstrap your app, before anything else. Then you won't have such issues. An example from the docs, where two schema reference each other:

http://mongoosejs.com/docs/populate.html

var mongoose = require('mongoose')
  , Schema = mongoose.Schema

var personSchema = Schema({
  _id     : Number,
  name    : String,
  age     : Number,
  stories : [{ type: Schema.Types.ObjectId, ref: 'Story' }]
});

var storySchema = Schema({
  _creator : { type: Number, ref: 'Person' },
  title    : String,
  fans     : [{ type: Number, ref: 'Person' }]
});

var Story  = mongoose.model('Story', storySchema);
var Person = mongoose.model('Person', personSchema);
