Class Method Details

.ensure_translatable_attributes(base) ⇒ Object

Only called once per class or inheritance chain (e.g. once for the superclass, not at all for subclasses). The separation is important if we don’t want to overwrite values if running multiple times in the same class or in different classes of an inheritance chain.
