    <p>I am using Angular 1.2-RC2 (also tried 1.0.8 and 1.1.x) and the ngResource module. The backend is a Spring WebMVC application.</p> <pre><code>angular.module("dox", ['ngResource']) .controller('SettingsController', function ($scope, Settings) { $scope.settings = Settings.query(); $scope.save = function () { Settings.save(); }; }) .factory('Settings', function ($resource) { return $resource('/api/v1/settings/:settingId', {settingId: '@id'}, { 'save': { method: 'POST', headers: { 'Content-Type': 'application/json' } } }); }); </code></pre> <p>Whenever the save() method on the Settings class gets called the frontend receives a HTTP 415 (Unsupported media type). The reason is that AngularJS send the POST request using the following content type:</p> <pre><code>Content type: text/plain;charset=UTF-8 </code></pre> <p>but the backend expects </p> <pre><code>Content type: application/json;charset=UTF-8 </code></pre> <p>According the <a href="http://docs.angularjs.org/api/ngResource.$resource" rel="nofollow noreferrer">API docs</a> it should be possible to override the header but my settings are somehow ignored. I seems that this is a common problem and as a <a href="https://stackoverflow.com/questions/17211443/angularjs-change-content-type-to-application-json-post-method-restful-api">workaround</a> there are many recommendation to use $http.post instead of $resource.</p> <p>Can you give me any hint how to solve this content type problem using the $resource service?</p> <p>Please find the backend controller code <a href="https://github.com/saw303/dox/blob/angularjs/web/src/main/java/ch/silviowangler/dox/web/rest/RestSettingsController.java#L71" rel="nofollow noreferrer">here</a>.</p>

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.
