Class Method Details

.generate(source_locale: :en, destination_locale: :zz) ⇒ Object

Creates the dummy locale from the source locale and hooks ‘I18n.reload!`

When Rails or other code calls ‘I18n.reload!` to pick up new and modified entries, DummyLocale will regenerate the locale from the updated source. This helps us seamlessly pick up translation changes in development.
