A client for the Attune ranking API. Built using the excellent faraday library.


Add this line to your application’s Gemfile:

gem 'attune'

And then execute:

$ bundle


Example rails usage

Requests are performed through a client object

ruby client =

Visitors to the application should be tagged with an anonymous user id

``` ruby class ApplicationController before_filter do session[:attune_id] ||= end

private def attune_client @attune_client ||= Attune.client end end ```

The user id can be bound to a customer id at login

``` ruby class SessionsController # …

def create # … attune_customer = attune_client.anonymous.update(session[:attune_id], attune_customer) end end ```

The client can then perform rankings

``` ruby class ProductsController def index @products = sorted(Product.all) end

private def sorted products ranking_params = ranking_params.anonymous = session[:attune_id] ranking_params.view = request.fullpath ranking_params.entity_type = ‘products’ ranking_params.user_agent = request.env[“HTTP_USER_AGENT”] ranking_params.ids = scope = = ‘category’ scope.value = ‘pants’ ranking_params.scope = [scope] ranking = attune_client.entities.get_rankings(ranking_params) products.sort_by do |product| ranking.ranking.index( end end end ```

The client provides a way to request a new auth_token through the API

ruby client = auth_token = client.get_auth_token('my-client-id', 'my-client-secret')

Also see Blacklist examples for examples of our blacklist API.


Attune can be configured globally

ruby Attune.configure do |c| c.auth_token = "my-secure-auth-token" c.endpoint = "" c.timeout = 5 end

Settings can also be overridden on a client object

ruby client = "my-secure-auth-token", timeout: 2)

See the documentation for Attune::Configurable and the default configuration for more details.


How to identify attune vs control in the browser?

You can identify the cell assignment by fetching the data in the below variable
    # @attr [String] cell Cell assignment


For testing and development, the ranking API can be simulated using.

ruby Attune.test_mode!

In this mode no API calls will be made, and rankings will be returned in their original order. Calling .test_mode! is equivalent to setting disabled to true and exception_handler to :mock.
