# The code below patches I18n to raise exceptions for all errors, including translation errors. # The default (unpatched) behavior in Rails 2.2.2 rescues translation errors and returns the failed # translation keys as a string. This behavior is undesirable in test, because it makes it too # easy for translation errors to go unnoticed when running automated tests. Instead, we want to fail noisily. # # == Usage # (within test_helper) # require File.dirname(__FILE__) + '/i18n_patch' # Patch translation within views module ActionView module Helpers module TranslationHelper def translate(key, options = {}) options[:raise] = true I18n.translate(key, options) rescue I18n::MissingTranslationData => e raise e if RAILS_ENV == 'test' # <<< this line is the patch. everything else in this method is original. keys = I18n.send(:normalize_translation_keys, e.locale, e.key, e.options[:scope]) content_tag('span', keys.join(', '), :class => 'translation_missing') end alias :t :translate def localize(*args) I18n.localize *args end alias :l :localize end end end # Patch translation in models and controllers module I18n class << self def raise_all_exceptions(*args) raise args.first end end end I18n.exception_handler = :raise_all_exceptions
