    <p>You can use the repo below to guide you on how to do embedded association. Though they are not using mongodb, the important thing is on the ember-data side, they are doing embedded association.</p> <p><a href="https://github.com/dgeb/ember_data_example/blob/master/app/assets/javascripts/controllers/contact_edit_controller.js" rel="nofollow">https://github.com/dgeb/ember_data_example/blob/master/app/assets/javascripts/controllers/contact_edit_controller.js</a></p> <p>Note that here App.PhoneNumber is embedded in App.Contact. But it should give you an idea on how to go abut resolving yours.</p> <pre><code>App.Contact = DS.Model.extend({ firstName: DS.attr('string'), lastName: DS.attr('string'), email: DS.attr('string'), notes: DS.attr('string'), phoneNumbers: DS.hasMany('App.PhoneNumber'), }); App.PhoneNumber = DS.Model.extend({ number: DS.attr('string'), contact: DS.belongsTo('App.Contact') }); </code></pre> <p><a href="https://github.com/dgeb/ember_data_example/blob/master/app/assets/javascripts/store.js" rel="nofollow">https://github.com/dgeb/ember_data_example/blob/master/app/assets/javascripts/store.js</a></p> <pre><code>App.Adapter = DS.RESTAdapter.extend({ bulkCommit: false }); App.Adapter.map('App.Contact', { phoneNumbers: {embedded: 'always'} }); App.Store = DS.Store.extend({ revision: 12, adapter: App.Adapter.create() }); </code></pre> <p><a href="https://github.com/dgeb/ember_data_example/blob/master/app/assets/javascripts/controllers/contact_edit_controller.js" rel="nofollow">https://github.com/dgeb/ember_data_example/blob/master/app/assets/javascripts/controllers/contact_edit_controller.js</a></p> <pre><code>App.ContactEditController = Em.ObjectController.extend({ needs: ['contact'], startEditing: function() { // add the contact and its associated phone numbers to a local transaction var contact = this.get('content'); var transaction = contact.get('store').transaction(); transaction.add(contact); contact.get('phoneNumbers').forEach(function(phoneNumber) { transaction.add(phoneNumber); }); this.transaction = transaction; }, save: function() { this.transaction.commit(); }, addPhoneNumber: function() { this.get('content.phoneNumbers').createRecord(); }, }); </code></pre>

    1. COI'll have to check it out closer, but do you know if, once you have a phoneNumber if you are able to reference the contact? That backwards relationship is the part giving me a hard time.

    2. COThe App.Adapter.map line gives me: `Uncaught TypeError: Cannot call method 'map' of undefined...` I guess this has changed in ember1.0 ?

    3. COIn the current version. ember-data, things have changed much and some things in this code no longer apply. the **RestAdapter, no longer needs to be declare as it is done automatically but if you are using the **fixtureAdapter in jsfiddle, that should be declared. Also you no longer define **App.Store** except if you want to extend something. **Embedding**, relationships is temporarily removed but will be re-added in future. With **rails** and **emberjs**, use the **activemodeladapter** that comes bundled with ember-data. defining **relationship** has changed. See: **http://bit.ly/14Pl9Av**

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
