+# This module provides methods for controllers that have to deal with tag
+# references (i.e. comments and things). This is closely tied to `TagReference`
+# and its polymorphic `:taggable` column.
+module Taggable
+  extend ActiveSupport::Concern
+
+  # Update tag references for the given `object` with tags identified by the
+  # `ids` array.
+  def update_tags!(object:, ids:)
+    object.tag_references.destroy_all
+    return true unless ids

+    ids.each { |id| TagReference.create!(tag_id: id, taggable: object) }
