AngularJS + Rails - Problems when compressing assets

I recently created an AngularJS 1.0.0rc8 app with a Rails 3.2.3 back-end and it worked fine in development, but after deploying to Heroku there was a Unknown Provider error - apparently the app could not see the service object. I know that it's now necessary to include angular-resource.js as a separate file and inject ngResource into the app module like this: ``` // main app javascript file 'use strict'; angular.module('contactapp', ['ngResource']). config(['$routeProvider', function($routeProvider) { $routeProvider. when('/contacts', {template: 'assets/app/partials/contact-list.html', controller: ContactListCtrl}). when('/contacts/new', {template: 'assets/app/partials/new-contact.html', controller: ContactListCtrl}). when('/contacts/:contact_id', {template: 'assets/app/partials/contact-detail.html', controller: ContactDetailCtrl}). otherwise({redirectTo: '/contacts'}); }]); ``` I also know that when files are minified that the controllers can't tell what their dependencies are unless they are also injected into the controller objects like this: ``` ContactListCtrl.$inject = ['$scope', '$http', 'Contacts']; ``` I've also tried doing it the other way that Angular recommends with bracket notation and passing in a function like this: ``` var ContactListCtrl= ['$scope', '$http', 'Contacts', function($scope, $http, Contacts) { /* constructor body */ }]; ``` However, none of this seems to work. The only way my application could see the resource provided was by turning off asset compression in the Production.rb file, like this: ``` # Compress JavaScripts and CSS config.assets.compress = false ``` It took several hours for me to figure this out, but I recently saw another Rails + AngularJS app that had the same issue. Jens Krause came to the same conclusion and explains it on his blog: http://www.websector.de/blog/2012/01/17/fun-with-angularjs-rails-coffeescript-sass-another-cafe-townsend-example/ If I have a relatively large app, and I need to compress the assets, how do I get around this using Angular with Rails? Thanks.
