mongoose - possible circular dependency?

Question

I have the following mongoose models in my express app:

//user.js
var mongoose  = require(\'mongoose\');
var dog       = require(\'./dog\');

var userSchema = mo

You can create simultaneous references in two directions without creating circular problems. Create a reference from one document to the other using ref. From the docs:

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);

Then you can then choose to load the sub document using populate

Story.find({ --your criteria-- })
    .populate('_creator')
    .exec(function (err, story) {../});

You can then store the 2 schemas in separate .js files and require them both
