def acts_as_tagger(opts={})
  class_eval do
    owned_taggings_scope = opts.delete(:scope)

    has_many :owned_taggings, owned_taggings_scope,
             opts.merge(
               as: :tagger,
               class_name: ::ActsAsTaggableOn::Tagging,
               dependent: :destroy
             )
