如何限制发送到 Algolia 的记录?

How to limit what records are sent to Algolia?

在 Rails 上使用 Ruby 中的 Algolia,我可以轻松地为模型建立索引:

class Service < ActiveRecord::Base
  include AlgoliaSearch

  algoliasearch per_environment: true do
    attributesToIndex ['name', 'canonical_url']
    attributes ['name', 'canonical_url]
    add_attribute :type do
      "Service"
    end
  end
end

有什么方法可以限制我要发送的Service

例如:Only index Services where name != nil

绝对可以做到: https://github.com/algolia/algoliasearch-rails#restrict-indexing-to-a-subset-of-your-data

class Service < ActiveRecord::Base
  include AlgoliaSearch

  algoliasearch if: :name? do
  end

end
