    <p>You can search the Ember.JS source for all of these by searching for: <code>Ember.Handlebars.registerHelper('?'</code>. For example, to find the part where <code>template</code> is defined, search for: <strong>Ember.Handlebars.registerHelper('template'</strong></p> <p><strong>{{template}}</strong></p> <p>Is similar to the <code>{{partial}}</code>, but looks for templates that you define in the <code>Ember.TEMPLATES</code> hash. From the source code we can see an example: <code>Ember.TEMPLATES["my_cool_template"] = Ember.Handlebars.compile('&lt;b&gt;{{user}}&lt;/b&gt;');</code> and then we can render it that way.</p> <p>I heard a whisper that <code>{{template}}</code> is <strong>@deprecated</strong>, but I can't find where I found that information at the moment. However, it's worth mentioning that I've never found myself using this one. Instead I prefer <code>{{partial}}</code>.</p> <p><strong>Edit:</strong> It appears as though it isn't <strong>@deprecated</strong> as of <code> 3df5ddfd4f</code>. My mistake!</p> <p><strong>{{partial}}</strong></p> <p>This is different to the <code>{{render}}</code> approach in that the <code>controller</code> and <code>view</code> are inherited from the context that called it. For example, if you're in the <code>UserRoute</code>, and you load in a partial in your user template, then the <code>UserView</code> and <code>UserController</code> will both be passed to your partial, so they can access exactly the same information as its current parent.</p> <p>Partial names, when defined, start with an underscore. For instance, a <code>Profile</code> partial will have the <code>data-template-name</code> of: <code>data-template-name="_profile"</code> but is inserted into your view as <code>{{partial "profile"}}</code>.</p> <p><strong>{{outlet}}</strong></p> <p>You'll probably find yourself using this one a lot. It's predominantly used in cases where the <code>outlet</code> changes frequently, based on user interactions. By transitioning to (<code>this.transitionTo</code>/<code>{{#linkTo}}</code>) another page, Ember inserts the view into the <code>{{outlet}}</code> and attaches the relevant <code>controller</code> and <code>view</code>.</p> <p>As an example, if you're transitioning into <em>/#/pets</em> then, by default, Ember will load the <code>PetsView</code> into the <code>{{outlet}}</code>, and attach the <code>PetsController</code>, all of this after initialising the <code>PetsRoute</code> to take instructions before initialising the view and finding the controller.</p> <p><strong>{{render}}</strong></p> <p>This is a mixture of an <code>{{outlet}}</code> and a <code>{{partial}}</code>. It's used for static pages that don't switch out for other pages (as an <code>outlet</code> does), but it doesn't inherit the controller and view (as a <code>partial</code> does).</p> <p>It's better with an example. Let's say you've got a navigation. Usually you'll only have one navigation, and it won't change for another one, but you want the navigation to have its own controller and view, and not to be inherited from the context (probably <code>ApplicationRoute</code>). Therefore when you insert the navigation (<code>{{render "navigation"}}</code>), Ember will attach <code>App.NavigationController</code> and <code>App.NavigationView</code>.</p> <p><strong>Summary</strong></p> <ul> <li><code>template</code>: Consults a global hash and inserts the view when it finds it (possibly soon to be <strong>@deprecated</strong>);</li> <li><code>partial</code>: Used to split up complicated views, and inherits the controller/view from the parent (if you're in the <code>UserController</code>, then the partial will also have access to this, and its associated view).</li> <li><code>outlet</code>: Most widely used, and allows you to quickly switch out pages for other pages. Relevant controller/view attached.</li> <li><code>render</code>: Similar to an outlet, but is used for pages that are persistent across the entire application. Assumes the relevant controller/view, and <strong>doesn't</strong> inherit them.</li> </ul> <p>Did I explain them well?</p> <p>Just to clarify:</p> <ul> <li>Partial: Inherited controller, inherited view, non-switchable;</li> <li>Outlet: Relevant controller, relevant view, switchable;</li> <li>Render: Relevant controller, relevant view, non-switchable;</li> </ul>

    1. COAwesome answer, vote up! This actually confirms what I was assuming the different keywords do. Would be great if someone can confirm the @deprecated.

    2. COMy pleasure! It's useful for me as well, especially as I've just compiled the very latest version of Ember after a `git pull`, and put together a JSFiddle to demonstrate everything: http://jsfiddle.net/HvXNh/ It appears as though `{{render}}` isn't **@deprecated** as I thought. The JSFiddle should help you understand the differences.

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.
