Async OneToMany relationship returning just one record

Ember Data
1

I have two models setup, a User model and a Company model.

/models/company.js

import DS from 'ember-data';

export default DS.Model.extend({
  name: DS.attr('string'),
  logo: DS.attr('string'),
  employees: DS.attr('number'),
  annualRevenue: DS.attr('number'),
  createdTime: DS.attr('date'),
  updatedTime: DS.attr('date'),
  description: DS.attr('string')
});

/models/user.js

import DS from 'ember-data';

export default DS.Model.extend({
  firstName: DS.attr('string'),
  lastName: DS.attr('string'),
  fullName: function() {
    return this.get('firstName') + ' ' + this.get('lastName');
  }.property('firstName', 'lastName'),
  email: DS.attr('string'),
  enabled: DS.attr('boolean'),
  companies: DS.hasMany('company', {async: true})
});

You’ll notice the async relationship between User > Company. A simple One to Many relationship.

When I request companies from the user model in my example I would expect to find three companies, however I’m only getting one.

userModel.get('companies').then(function(companies){
   console.log( companies.get('length') ); // 1
});

The interesting thing here is, before the promise is resolved there are three company model’s once resolved there is only one. Looking at Ember Inspector I can see that all three companies were saved correctly. However in the user model’s companies key I only find one company. It’s as if Ember Data is preserving the relationship correctly.

Am I doing something wrong here?

Thanks in advance for any help.

Perhaps you need to add DS.belongsTo to company.js

That fixed it, it makes perfect sense as soon as you said that. How else would ember know of the relationship. duh :slight_smile: thanks a bunch.
