History module is not compatible with using uuid as ids

[such]

When using uuids as id for the friendly_id_slugs table the history can be wrongly considered out of date.

I created the friendly_id_slugs table with create_table :friendly_id_slugs, id: :uuid.

In history.rb, the slugs relationship is defined as:

has_many :slugs, -> {order(id: :desc)}, **{
          :as         => :sluggable,
          :dependent  => @friendly_id_config.dependent_value,
          :class_name => Slug.to_s
        }

In order to find the current slug in history_is_up_to_date?, it uses: latest_history = slugs.first

ordering by id is not compatible with this when ids are uuids.

Potential solution:

Allowing configuration of the ordering key:

has_many :slugs, -> {order(@friendly_id_config.ordering_key => :desc)}, **{
          :as         => :sluggable,
          :dependent  => @friendly_id_config.dependent_value,
          :class_name => Slug.to_s
        }
