Ch3: Trouble with I18n validation posted by Bill Lazar @ Mon, 20 Jun 2011 01:40:38 +0000

When I include the line:

validates :locale, inclusion: I18N.available_locales.map(&:to_s)

I get an error on app startup:

uninitialized constant Cms::I18N (NameError)

(Cms being the model name)

Any thoughts on why this is happening?
Thanks,
Bill
