sorting - Drying up Models for Solr Sunspot searchable with Concerns -

i want dry models; sunspot allows one(1) "searchable" block in model. making 2 ignores second one. failed example below:

digital.rb

class digital < activerecord::base    include baseconcerns    belongs_to :digitable, polymorphic: true    # ignores   searchable      string :url     text :url      string :remark     text :remark    end  end 

base_concerns.rb

module baseconcerns extend activesupport::concern    included     before_create{       self.id = uuidtools::uuid.timestamp_create().to_s.downcase if id.blank?     }     self.primary_key = 'id'      #     searchable       text :id       time :created_at       time :updated_at     end    end  end 

i want dry models using concern , want named columns searchable; while others can specify; how can this?
