solidus_recommendations

SolidusRecommendations

Uses Elasticsearch on top of Solidus framework to retrieve relevant recommendations based on what users have purchased in the past.

Requirements

• Elasticsearch must be installed and running. https://www.elastic.co/downloads/elasticsearch

Installation

Add solidus_recommendations to your Gemfile:

gem 'solidus_recommendations'

Bundle your dependencies and run the installation generator:

bundle
bundle exec rails g solidus_recommendations:install

From the console:

Spree.user_class.__elasticsearch__.create_index!
Spree::Order.__elasticsearch__.create_index!

Spree.user_class.import
Spree::Order.import

Usage

We can get recommendations based on the product 123 by doing the following:

Spree::Product.recommendations.get(123)

The query defaults to at most 10 results, If you want more or less then you can use the size argument.

Spree::Product.recommendations.get(123, size: 5) # At most 5 results.

(Experimental) Currently we index the products a user has purchased as well as the products within each order. These two indices can say different things about our data. The user index gives results for "What did other users purchase that also purchased this product". The order index is for "What did other users checkout with that also checked out with this product". By default the user index is used to query for recommendations but that can be changed using the index argument. Acceptable values are [:user, :order].

Spree::Product.recommendations.get(123, index: :order)

Testing

Install elasticsearch, this is needed for rspec tests. If you have issues running tests, see https://github.com/elastic/elasticsearch-ruby/tree/master/elasticsearch-extensions#testcluster

First bundle your dependencies, then run rake. rake will default to building the dummy app if it does not exist, then it will run specs, and Rubocop static code analysis. The dummy app can be regenerated by using rake test_app.

bundle
bundle exec rake

When testing your applications integration with this extension you may use it's factories. Simply add this require statement to your spec_helper:
