Delegates to I18n.localize with no additional functionality.
# File lib/action_view/helpers/translation_helper.rb, line 37 def localize(*args) I18n.localize(*args) end
Delegates to I18n#translate but also performs two additional functions. First, it’ll catch MissingTranslationData exceptions and turn them into inline spans that contains the missing key, such that you can see in a view what is missing where.
Second, it’ll scope the key by the current partial if the key starts with a period. So if you call translate(“.foo”) from the people/index.html.erb template, you’ll actually be calling I18n.translate(“people.index.foo”). This makes it less repetitive to translate many keys within the same partials and gives you a simple framework for scoping them consistently. If you don’t prepend the key with a period, nothing is converted.
# File lib/action_view/helpers/translation_helper.rb, line 13 def translate(keys, options = {}) if multiple_keys = keys.is_a?(Array) ActiveSupport::Deprecation.warn "Giving an array to translate is deprecated, please give a symbol or a string instead", caller end options[:raise] = true keys = scope_keys_by_partial(keys) translations = I18n.translate(keys, options) translations = [translations] if !multiple_keys && translations.size > 1 translations = html_safe_translation_keys(keys, translations) if multiple_keys || translations.size > 1 translations else translations.first end rescue I18n::MissingTranslationData => e keys = I18n.send(:normalize_translation_keys, e.locale, e.key, e.options[:scope]) content_tag('span', keys.join(', '), :class => 'translation_missing') end
