Angular $resource experience with Rails based API

create_rails_api_request.coffee

# Create service for our factories. Don't blow .json extension. This is easiest path to get JSON request in AUTO mode.
angular.module("identityService", ["ngResource"])
.factory 'Identity', ($resource) ->
  $resource '/api/v1/identities/:id.json',
    { id:'@id' }

# Added update via PUT
@identities.config ($resourceProvider) ->
  $resourceProvider.defaults.actions.update = { method: 'PUT' }

# Run our test
@identities.controller 'RestaurantIndexCtrl', ($scope, Identity) ->  
  data = {
    identity: {
      user_id: 55
      provider: "vkontakte"
    }
  }
  
  Identity.save(data)
  Identity.update id:1, identity: {user_id:444}
