    <p>Due to the fact that angularjs is not working with ngResource custom url, I have to try $http instead:</p> <p>My html is something like:</p> <pre><code>//html &lt;tr ng-repeat="person in people"&gt; &lt;td&gt;{{person.name}}&lt;/td&gt; &lt;td&gt;&lt;a ng-click="changeGender(person)"&gt;{{person.gender}}&lt;/a&gt;&lt;/td&gt; &lt;/tr&gt; </code></pre> <p>my idea is after clicking the anchor in the html, a request will be sent to the server and update, then send the status with 200 back and update the gender in the view. I build a service and it look like:</p> <pre><code>//factory app.factory('changeGenderFactory', function($http, $q){ return { getResult: function(person) { var deferred = $q.defer(); $http({method: 'POST', url: '/resources/people/' + person.id + '/gender'}). success(function(data, status, headers, config){ deferred.resolve(data); }). error(function(data, status, headers, config){ deferred.reject(status); }); return deferred.promise; } }; }); </code></pre> <p>This is the controller:</p> <pre><code>//app var app = angular.module('someApp', []); //controller app.controller('peopleCtrl', function($scope, ngResource, changeGenderFactory) { //skip how i get $scope.people... //$scope.people = ...(use ngResource) $scope.changeGender = function(person) { return changeGenderFactory.getResult(person); }; }); </code></pre> <p>The ajax is working fine, but I guess something wrong with my controller part because the html is not updated at all. What should I do in order to update the data in ng-repeat in html? Thank you.</p>

    1. COYour function changeGender does not seem to touch $scope.people at all so it would be very surprising if anything changed.

    2. COThank you for pointing this out. I thought angular would bind this automatically. What should I do to update that particular row?

    3. COHave you tried wrapping Angular's $timeout service around your ngResource call inside your app.controller? I think what's happening here is your ng-repeater is referencing a $scope.people before the async request (your ngResource call) has returned. Therefore it is referencing undefined data that was returned synchronously in the form of a promise.

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.
