Service injection into controller with AngularJS

Question

I have written a service in AngularJS, but I can't get it to work with the angular-seed way of doing things.

The controller code is as follows:

/*function PhotoCtrl($scope, Photo) {     $scope.photos = Photo.query(); }*/  angular.module('myApp.controllers', []).     controller('PhotoCtrl', [function($scope,Photo) {     $scope.photos = Photo.query(); }]) .controller('MyCtrl2', [function() {  }]); 

Note that the commented out section works fine, but I would like to handle it somewhat like the (recommended) second way.

The error I get is that Photo is undefined, so my guess would be my method of passing (injecting) it is wrong, but I can't find out how to do it correctly

You need to define the Photo service:

angular.module('myApp.controllers', [])     .service('Photo', ['$log', function ($log) {          return {             query: function() {                 // the query code here.             }         };      }])     .controller('PhotoCtrl', ['$scope', 'Photo', function ($scope, Photo) {         $scope.photos = Photo.query();     }])     .controller('MyCtrl2', [function() {      }]); 

A couple of references:

• http://docs.angularjs.org/api/angular.Module
• http://docs.angularjs.org/api/AUTO.$provide#service

In the above sample code I used parameters aliasing, which I suggest in order to avoid issues when minifying your code.
