wrong belongsTo behavior when using with postgresql

[tanqhnguyen]

I have this schema definition

var Domain = schema.define('domain', {
  name: Number
});

var User = schema.define('user', {
  email: String
});

Domain.belongsTo(User, {as: 'user', foreignKey : 'user_id'});
User.hasMany(Domain, {as : 'domains', foreignKey: 'user_id'});

Then I created some domains and add them to a particular user. I have checked the database and everything is ok.

Then, I do

domain.user(); // It can get the user id

However if I do something like this

domain.user(function(error, user){
  // user should be a user record ?
});

I got this error

TypeError: Object #<Object> has no method 'find'
    at Object.domain (/home/vagrant/lib/node_modules/jugglingdb/lib/abstract-class.js:690:22)
    at ModelConstructor.domain (/home/vagrant/lib/node_modules/jugglingdb/lib/abstract-class.js:705:40)

I am using postgresql 9.1 on Ubuntu 11.10.

This error may happen when User is not defined correctly before calling
Domain.belongsTo. What if move relationships defenitions to proper place?
(I mead app/models/ dir)

BTW, model names should start with upper case letter.

Yes, I have just figured it out. I define models in separated files, which cause errors when models are related to each other. I have moved the relationship definition to a different file and call that file after all models are defined. It works now.
