    <p>In Ember.js if you have a model that has a one-to-many relationship is it possible to generate links based on a property of the parent model?</p> <p>For example, I have a model and some data like this:</p> <pre><code>var SuggestionGroup = Ember.Model.extend({ id: Ember.attr('number'), name: Ember.attr('string'), suggestions: Ember.hasMany('App.Suggestion', { key: 'suggestions', embedded: true }) }); SuggestionGroup.adapter = Ember.FixtureAdapter.create(); SuggestionGroup.FIXTURES = [ { id: 1, name: 'Start', suggestions: [ { id: 1, title: 'Fetching coffee and cake for the Interface Developers', description: 'Because they\'re so brilliant', upVotes: 10, downVotes: 2 }, { id: 2, title: 'Criticising the app devs more', description: 'They enjoy a bit of banter', upVotes: 8, downVotes: 4 }, { id: 3, title: 'Not updating JIRA', description: 'It\'ll be funny when the PMs start raging', upVotes: 1000000, downVotes: 0 } ] }] </code></pre> <p>And here are my routes:</p> <pre><code>App.Router.map(function() { this.resource('current-suggestions'); this.resource('suggestion', { path: '/current-suggestions/:suggestion_id' }); }); </code></pre> <p>My template is like this:</p> <pre><code>{{#each model}} &lt;td&gt; &lt;ul&gt; {{#each suggestions}} &lt;li class="suggestion"&gt; &lt;h3&gt; {{#linkTo 'suggestion' this}}{{title}}{{/linkTo}} &lt;/h3&gt; &lt;/li&gt; {{/each}} &lt;/ul&gt; &lt;/td&gt; {{/each}} </code></pre> <p>So, at the moment my paths are <code>current-suggestions/1</code>. But what I'd like to do is have paths such as <code>current-suggestions/Start/1</code>. So, the path is generated using a property from the parent model.</p> <p>Is it possible to do something like this?</p>

    1. COWhy not put a `belongsTo` relationship in the child? Then you can get a reference to the parent using get() and then get any properties you want.

    2. CO@GJK It's not accessing the parent's properties that I'm having trouble with. I want to use the parent's `name` property to create a path for each `Suggestion`. So if a `Suggestion`'s parent has a `name` of 'Start' then the path will be `current-suggestions/Start/1` or if it's 'Stop' then `current-suggestions/Stop/1`.

    3. COAhh, I see. I imagine the way to do it would be using a dynamic segment, but I'm not quite good enough to at Ember.js yet to know how to do that.

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.
