ruby-on-rails - Rails - 在模块上包含 Elasticsearch ？

Question

是否有可能拥有

include Elasticsearch::Model
include Elasticsearch::Model::Callbacks

在一个模块上？怎么样？

Answer 1

您可以使用 included ActiveSupport::Concern block 包括这些模块

就像是:

module MyElasticSupport
  extend ActiveSupport::Concern

  included do
    include Elasticsearch::Model
    include Elasticsearch::Model::Callbacks
  end

  ... some other code ...
end

class MyModel
  include MyElasticSupport

  ... some other code ...
end
