[searchkick](http://searchkick.org) 7 | 8 | Features 9 | -------- 10 | 11 | * Full search (keyword, in_taxon) 12 | * Taxons Aggregations (aggs) 13 | * Search Autocomplete ([Typeahead](https://twitter.github.io/typeahead.js/)) 14 | * Added `/best` route, where best selling products are boosted in first page 15 | 16 | 17 | Installation 18 | ------------ 19 | 20 | Add searchkick and spree_searchkick to your Gemfile: 21 | 22 | ```ruby 23 | gem 'searchkick' 24 | gem 'spree_searchkick', github: 'ronzalo/spree_searchkick', branch: '3-1-stable' 25 | ``` 26 | 27 | Bundle your dependencies and run the installation generator: 28 | 29 | ```shell 30 | bundle 31 | bundle exec rails g spree_searchkick:install 32 | bundle exec rails searchkick:reindex:all 33 | ``` 34 | 35 | [Install elasticsearch](https://www.elastic.co/downloads/elasticsearch) 36 | 37 | Documentation 38 | ------------- 39 | 40 | By default, only the `Spree::Product` class is indexed and to control what data is indexed, override `Spree::Product#search_data` method. Call `Spree::Product.reindex` after changing this method. 41 | 42 | To enable or disable taxons filters, go to taxonomy form and change `filterable` boolean. 43 | 44 | Testing 45 | ------- 46 | 47 | 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. The dummy app can be regenerated by using `rake test_app`. 48 | 49 | ```shell 50 | bundle 51 | bundle exec rake 52 | ``` 53 | 54 | When testing your applications integration with this extension you may use it's factories. 55 | Simply add this require statement to your spec_helper: 56 | 57 | ```ruby 58 | require 'spree_searchkick/factories' 59 | ``` 60 | 61 | Copyright (c) 2015 Gonzalo Moreno, released under the New BSD License 62 | -------------------------------------------------------------------------------- /spec/spec_helper.rb: -------------------------------------------------------------------------------- 1 | # Run Coverage report 2 | require 'simplecov' 3 | SimpleCov.start do 4 | add_filter 'spec/dummy' 5 | add_group 'Controllers', 'app/controllers' 6 | add_group 'Helpers', 'app/helpers' 7 | add_group 'Mailers', 'app/mailers' 8 | add_group 'Models', 'app/models' 9 | add_group 'Views', 'app/views' 10 | add_group 'Libraries', 'lib' 11 | end 12 | 13 | # Configure Rails Environment 14 | ENV['RAILS_ENV'] = 'test' 15 | 16 | require File.expand_path('../dummy/config/environment.rb', __FILE__) 17 | 18 | require 'rspec/rails' 19 | require 'database_cleaner' 20 | require 'ffaker' 21 | 22 | # Requires supporting ruby files with custom matchers and macros, etc, 23 | # in spec/support/ and its subdirectories. 24 | Dir[File.join(File.dirname(__FILE__), 'support/**/*.rb')].each { |f| require f } 25 | 26 | # Requires factories and other useful helpers defined in spree_core. 27 | require 'spree/testing_support/authorization_helpers' 28 | require 'spree/testing_support/capybara_ext' 29 | require 'spree/testing_support/controller_requests' 30 | require 'spree/testing_support/factories' 31 | require 'spree/testing_support/url_helpers' 32 | 33 | # Requires factories defined in lib/spree_searchkick/factories.rb 34 | require 'spree_searchkick/factories' 35 | 36 | RSpec.configure do |config| 37 | config.include FactoryBot::Syntax::Methods 38 | config.include Devise::Test::ControllerHelpers, type: :controller 39 | # Infer an example group's spec type from the file location. 40 | config.infer_spec_type_from_file_location! 41 | 42 | # == URL Helpers 43 | # 44 | # Allows access to Spree's routes in specs: 45 | # 46 | # visit spree.admin_path 47 | # current_path.should eql(spree.products_path) 48 | config.include Spree::TestingSupport::ControllerRequests, type: :controller 49 | config.include Spree::TestingSupport::UrlHelpers 50 | config.include Spree::TestingSupport::AuthorizationHelpers 51 | 52 | # == Mock Framework 53 | # 54 | # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line: 55 | # 56 | # config.mock_with :mocha 57 | # config.mock_with :flexmock 58 | # config.mock_with :rr 59 | config.mock_with :rspec 60 | config.color = true 61 | 62 | # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures 63 | config.fixture_path = "#{::Rails.root}/spec/fixtures" 64 | 65 | # Capybara javascript drivers require transactional fixtures set to false, and we use DatabaseCleaner 66 | # to cleanup after each test instead.
