Rails could not load static html template with angular.js - ruby-on-rails

Question

I got this exception
No route matches [GET] "/ng-template/manager/index.html"
Everything works fine on my local machine, but failed after deploying to staging server.
Any idea?
angular route
App.config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/',
{
templateUrl: '/ng-template/manager/index.html',
controller: 'indexCtrl'}
).
when('/api_usage',
{
templateUrl: '/ng-template/manager/api_usage.html',
controller: 'ApiUsageCtrl'
}
