Here, I've created a ModelProxy mixin so I can have an intermediate proxy object to work with: <pre><code>var defineProperty = Ember.defineProperty; var ModelProxy = Ember.ObjectProxy.extend({ model: Ember.computed.alias('content'), // override this ObjectProxy method to not propagate changes to the model setUnknownProperty: function(key, value) { defineProperty(this, key, null, value); return value; }, // only propagate proxy attributes when the proxy is saved save: function() { var keys = Em.keys(this), content = this.get('content'); keys.forEach(function(key) { content.set(key, self.get(key)); }, this); return content.save(); } }); var ModelProxyMixin = Ember.Mixin.create({ proxy: null, init: function() { this._super(); this.set('proxy', ModelProxy.create({ model: this })); }, }); </code></pre> This is mixed into the Sequence model: <pre><code>var Sequence = DS.Model.extend(ModelProxyMixin, { /*..*/ }); </code></pre> The movies/edit template then uses the proxy when displaying the in-line form fields: <pre><code>{{#each s in sequences itemController='sequence'}} {{#if isEditing}} {{#with s.proxy}} <tr> <td><button {{action 'save'}}>Save</td> <td>{{input value=start}}</td> </tr> {{/with}} </code></pre> The SequenceController calls #save on the proxy which will then update the original model: <pre><code>actions: { save: function() { this.get('model.proxy').save().then(function() { this.toggleProperty('isEditing'); }); } </code></pre>

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.
