Generate a migration with polymorphic association

The migration generator has an option to create a polymorphic reference:

rails g migration add_taggable_to_tags taggable:references{polymorphic}

It will generate the following migration:

def change
  add_reference :tags, :taggable, polymorphic: true, index: true
