Public Instance Methods

default_error_message(key, options = {}) click to toggle source

Helper method that determines the default error message used by Active Record. Works for both existing Rails 2.1 and Rails 2.2 with the newly introduced I18n module used for localization. Use with Rails 3.0 and up will delegate to ActiveModel::Errors.generate_error if a model instance is given.
