    <p>I'm doing a project with angularjs and have a bit of trouble figuring out some things. So basically I'm getting a .json via an api which contains some university courses. I like to display them and when I click on one of them the detail page should be displayed.</p> <pre><code>function getcourses($scope, $http, $location, $rootScope){ $scope.init = function (){ $scope.apiroot = "http://...."; $http.get($scope.apiroot + 'courses.json').then(function(response){ $scope.courses = response.data.courses; }) }; $scope.selectCourse = function (index) { $scope.detailcourse = $scope.courses[index]; $location.path('/course'); }; } </code></pre> <p>courses.html:</p> <pre><code>&lt;table ng-controller="getcourses" data-ng-init="init()"&gt; ... &lt;li ng-repeat="course in courses"&gt; &lt;a ng-click="selectCourse($index)" ng-href=""&gt;{{course.title}}&lt;/a&gt; &lt;/li&gt; </code></pre> <p>course.html:</p> <pre><code>&lt;div class="panel panel-small" ng-controller="getcourses"&gt; &lt;div class="panel-heading"&gt;{{detailcourse.title}}: {{detailcourse.subtitle}}&lt;/div&gt; &lt;div class="list-group"&gt; &lt;class="list-group-item"&gt;{{detailcourse.description}}&lt;/class&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>This way, when I click on a link and get redirected nothing is shown. I guess because it gets all the courses again as soon as the other page gets loaded? I got it working with a rootScope but I think that's not very pretty. So what's the best way to do something like this?</p>

    1. COYour best bet is probably to setup a separate route for the course details page. Then you can use `$routeParams` to load the details for that course.

    2. COHow would I use that? I could route to let's say /coursetitle but then I would only have the title available through routeParams on the detail page right? Because the courses object is gone again.

    3. COYou would need to make another call to the server to get the data for just that course. If it were me I would probably use something like the course_id if one is available in the route. For example your route could be /course/54321, when that route loads you get the course_id and query the server to retrieve and then display that data. When I have some free time I could work on a example of how that could work.

Querying!

 
Guidance
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.
