@name Tutorial: 6 - Templating Links & Images
@description

<ul doc-tutorial-nav="6"></ul>


In this step, you will add thumbnail images for the phones in the phone list, and links that, for
now, will go nowhere. In subsequent steps you will use the links to display additional information
about the phones in the catalog.


<div doc-tutorial-reset="6"></div>


You should now see links and images of the phones in the list.

The most important changes are listed below. You can see the full diff on {@link
https://github.com/angular/angular-phonecat/compare/step-5...step-6
GitHub}:


## Data

Note that the `phones.json` file contains unique ids and image urls for each of the phones. The
urls point to the `app/img/phones/` directory.

__`app/phones/phones.json`__ (sample snippet):
<pre>
 [
  {
   ...
   "id": "motorola-defy-with-motoblur",
   "imageUrl": "img/phones/motorola-defy-with-motoblur.0.jpg",
   "name": "Motorola DEFY\u2122 with MOTOBLUR\u2122",
   ...
  },
 ...
 ]
</pre>


## Template

__`app/index.html`:__
<pre>
...
        <ul class="phones">
          <li ng-repeat="phone in phones | filter:query | orderBy:orderProp" class="thumbnail">
            <a href="#/phones/{{phone.id}}" class="thumb"><img ng-src="{{phone.imageUrl}}"></a>
            <a href="#/phones/{{phone.id}}">{{phone.name}}</a>
            <p>{{phone.snippet}}</p>
          </li>
        </ul>
...
</pre>

To dynamically generate links that will in the future lead to phone detail pages, we used the
now-familiar double-curly brace binding in the `href` attribute values. In step 2, we added the
`{{phone.name}}` binding as the element content. In this step the `{{phone.id}}` binding is used in
the element attribute.

We also added phone images next to each record using an image tag with the {@link
api/ng.directive:ngSrc ngSrc} directive. That directive prevents the
browser from treating the angular `{{ expression }}` markup literally, and initiating a request to
invalid url `http://localhost:8000/app/{{phone.imageUrl}}`, which it would have done if we had only
specified an attribute binding in a regular `src` attribute (`<img  class="diagram" src="{{phone.imageUrl}}">`).
Using `ngSrc` (`ng-src`) prevents the browser from making an http request to an invalid location.


## Test

__`test/e2e/scenarios.js`__:
<pre>
...
    it('should render phone specific links', function() {
      input('query').enter('nexus');
      element('.phones li a').click();
      expect(browser().location().url()).toBe('/phones/nexus-s');
    });
...
</pre>

We added a new end-to-end test to verify that the app is generating correct links to the phone
views that we will implement in the upcoming steps.

You can now refresh the browser tab with the end-to-end test runner to see the tests run, or you
can see them running on {@link
http://angular.github.com/angular-phonecat/step-6/test/e2e/runner.html
angular's server}.

# Experiments

* Replace the `ng-src` directive with a plain old `src` attribute. Using tools such as Firebug,
or Chrome's Web Inspector, or inspecting the webserver access logs, confirm that the app is indeed
making an extraneous request to `/app/%7B%7Bphone.imageUrl%7D%7D` (or
`/app/{{phone.imageUrl}}`).


# Summary

Now that you have added phone images and links, go to {@link step_07 step 7} to learn about angular
layout templates and how angular makes it easy to create applications that have multiple views.
