如何将此代码重构到某个范围

Answer 1

目前尚不清楚您真正想要存档的内容。在不知道上下文的情况下，我会将您的代码重写为以下内容：

%w( ads events pets companies ).each do |name|
  class_eval <<-END_OF_RUBY, __FILE__, __LINE__ + 1

    def #{name}
      @#{name} = search
    end

  ENF_OF_RUBY
end

private 
  def search
    @search.result.recent.completed.paginate(page: params[:page], per_page: 10).limit(10)
  end
