    <p>I am using Ember RC2 and Ember-Data 12 have the following relationship (simplified): </p> <pre><code>App.GlobalData = DS.Model.extend({ lat: DS.attr('number'), lon: DS.attr('number'), }); App.System = DS.Model.extend({ title: DS.attr('string'), data: DS.belongsTo('App.GlobalData'), }); </code></pre> <p>In my (System) view I now want to access the child's data like this: <code>{{ data.lat }}</code> </p> <p>It seems like Ember (currently I am using the FixtureAdapter, but I would also like to make this work with the RESTadapter in the future) does not automatically load the child element data. While <code>{{ data.id }}</code> returned the value of the id (as specified in the App.GlobalData.FIXTURES), <code>{{ data.lat }}</code> returned <code>undefined</code>.</p> <p>I somewhat got around this issue by creating an array controller:</p> <pre><code>App.GlobalDatasController = Ember.ArrayController.extend({}); App.globalDatasController = App.GlobalDatasController.create({}); </code></pre> <p>and preloading all GlobalData in my ApplicationRoute</p> <pre><code>App.ApplicationRoute = Ember.Route.extend({ setupController: function() { App.globalDatasController.set('content', App.GlobalData.find()); } }); </code></pre> <p>However, this does not seem like a good solution, because it requires me to load <em>all</em> GlobalData, even though I may only need one.</p> <p>I am sure there is a best practice on how to handle this, however, despite my best research efforts I have not been able to find it. </p> <p>To summarize my question: </p> <ol> <li>How and where do I tell ember to load child data with the parent (without sideloading it)?</li> <li>If sideloading is the only option, how would I implement that in the FixtureAdapter?</li> </ol> <p>Thanks!</p>

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.
