    <p>In my ember app, I have a router with nested resources, like so:</p> <pre><code>App.Router.map(function () { this.resource('explore', function() { this.resource('building', { path: 'building/:slug' }); this.resource('country', { path: ':slug' }, function() { this.resource('state', {path: ':slug' }); }); }); }); App.CountryRoute = Ember.Route.extend(App.SlugRouter, { setupController: function(controller, country) { controller.set('title', 'country detail'); controller.set('model', country); } }); App.SlugRouter = Ember.Mixin.create({ serialize: function(model, params) { var name, object; object = {}; name = params[0]; object[name] = model.get('slug'); return object; } }); App.Building = DS.Model.extend({ country: DS.belongsTo('App.Country'), name: DS.attr('string'), slug: DS.attr('string') }); App.Country = DS.Model.extend({ name: DS.attr('string'), slug: DS.attr('string'), buildings: DS.hasMany('App.Building'), states: DS.hasMany('App.State') }); </code></pre> <p>Loading the explore route shows a list of buildings received from the server (a django-rest-framework app), each building has a relationship to a country with a belongsTo attribute. </p> <p>In the explore.index route, I display the list of the buildings, with links to the country route for each building, using <code>{{linkTo this.country}}</code>. The href, however, is loaded as <code>#/explore/undefined</code>, instead of <code>#/explore/&lt;country-name&gt;</code>.</p> <p>The part that is confusing me is that this only happens the first time that I load the list. If I go to another route, then come back to <code>#/explore</code>, the links render correctly. </p> <p>In the debugger, putting a breakpoint in the serialize method, I see that the first time that I load the page, the model object is empty (_data.attributes is an empty object). Going to the network tab in the debugger, I see that the a request has been made to the server to get the country data, but the response has not been received yet:</p> <p><img src="https://i.stack.imgur.com/m2GK3.png" alt="server response not received yet"></p> <p>The response is eventually received, since <code>{{this.country.name}}</code> renders correctly, but after it's too late. </p> <p>Thanks in advance for any responses/tips. </p> <p>I am using: Ember: 1.0.0-rc.5, Handlebars: 1.0.0-rc.4, jQuery: 1.8.3, ember-data: 0.13, ember-data-django-rest-adapter: 0.13</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.
