@name Tutorial: 8 - More Templating
@description

<ul doc-tutorial-nav="8"></ul>


In this step, you will implement the phone details view, which is displayed when a user clicks on a
phone in the phone list.


<div doc-tutorial-reset="8"></div>


Now when you click on a phone on the list, the phone details page with phone-specific information
is displayed.

To implement the phone details view we will use {@link api/ng.$http $http} to fetch
our data, and we'll flesh out the `phone-detail.html` view template.

The most important changes are listed below. You can see the full diff on {@link
https://github.com/angular/angular-phonecat/compare/step-7...step-8
GitHub}:

## Data

In addition to `phones.json`, the `app/phones/` directory also contains one json file for each
phone:

__`app/phones/nexus-s.json`:__ (sample snippet)
<pre>
{
  "additionalFeatures": "Contour Display, Near Field Communications (NFC),...",
  "android": {
      "os": "Android 2.3",
      "ui": "Android"
  },
  ...
  "images": [
      "img/phones/nexus-s.0.jpg",
      "img/phones/nexus-s.1.jpg",
      "img/phones/nexus-s.2.jpg",
      "img/phones/nexus-s.3.jpg"
  ],
  "storage": {
      "flash": "16384MB",
      "ram": "512MB"
  }
}
</pre>


Each of these files describes various properties of the phone using the same data structure. We'll
show this data in the phone detail view.


## Controller

We'll expand the `PhoneDetailCtrl` by using the `$http` service to fetch the json files. This works
the same way as the phone list controller.

__`app/js/controllers.js`:__
<pre>
var phonecatControllers = angular.module('phonecatControllers',[]);

phonecatControllers.controller('PhoneDetailCtrl', ['$scope', '$routeParams', '$http',
  function($scope, $routeParams, $http) {
    $http.get('phones/' + $routeParams.phoneId + '.json').success(function(data) {
      $scope.phone = data;
    });
  }]);
</pre>

To construct the URL for the HTTP request, we use `$routeParams.phoneId` extracted from the current
route by the `$route` service.


## Template

The TBD placeholder line has been replaced with lists and bindings that comprise the phone details.
Note where we use the angular `{{expression}}` markup and `ngRepeat` to project phone data from
our model into the view.


__`app/partials/phone-detail.html`:__
<pre>
<img ng-src="{{phone.images[0]}}" class="phone">

<h1>{{phone.name}}</h1>

<p>{{phone.description}}</p>

<ul class="phone-thumbs">
  <li ng-repeat="img in phone.images">
    <img ng-src="{{img}}">
  </li>
</ul>

<ul class="specs">
  <li>
    <span>Availability and Networks</span>
    <dl>
      <dt>Availability</dt>
      <dd ng-repeat="availability in phone.availability">{{availability}}</dd>
    </dl>
  </li>
    ...
  </li>
    <span>Additional Features</span>
    <dd>{{phone.additionalFeatures}}</dd>
  </li>
</ul>
</pre>

<div style="display: none">
TODO!
<img  class="diagram" src="img/tutorial/tutorial_08-09_final.png">
</div>

## Test

We wrote a new unit test that is similar to the one we wrote for the `PhoneListCtrl` controller in
step 5.

__`test/unit/controllersSpec.js`:__
<pre>
...
  describe('PhoneDetailCtrl', function(){
    var scope, $httpBackend, ctrl;

    beforeEach(inject(function(_$httpBackend_, $rootScope, $routeParams, $controller) {
      $httpBackend = _$httpBackend_;
      $httpBackend.expectGET('phones/xyz.json').respond({name:'phone xyz'});

      $routeParams.phoneId = 'xyz';
      scope = $rootScope.$new();
      ctrl = $controller('PhoneDetailCtrl', {$scope: scope});
    }));


    it('should fetch phone detail', function() {
      expect(scope.phone).toBeUndefined();
      $httpBackend.flush();

      expect(scope.phone).toEqual({name:'phone xyz'});
    });
  });
...
</pre>

You should now see the following output in the Karma tab:

    Chrome 22.0: Executed 3 of 3 SUCCESS (0.039 secs / 0.012 secs)


We also added a new end-to-end test that navigates to the Nexus S detail page and verifies that the
heading on the page is "Nexus S".

__`test/e2e/scenarios.js`:__
<pre>
...
  describe('Phone detail view', function() {

    beforeEach(function() {
      browser().navigateTo('../../app/index.html#/phones/nexus-s');
    });


    it('should display nexus-s page', function() {
      expect(binding('phone.name')).toBe('Nexus S');
    });
  });
...
</pre>


You can now rerun `./scripts/e2e-test.sh` or 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-8/test/e2e/runner.html
Angular's server}.


# Experiments

* Using the {@link guide/dev_guide.e2e-testing Angular's end-to-end test runner API}, write a test
that verifies that we display 4 thumbnail images on the Nexus S details page.


# Summary

Now that the phone details view is in place, proceed to {@link step_09 step 9} to learn how to
write your own custom display filter.
