Rails-在模块上包括elasticsearch吗？

Question

是否有可能

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

在模块上？ 怎么会这样呢？

Answer 1

您可以使用ActiveSupport :: Concern的 included块来包含这些模块

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
