 The +translate+ method also takes a +:scope+ option which can contain one or more additional keys that will be used to specify a “namespace” or scope for a translation key:
 
 <ruby>
-I18n.t :invalid, :scope => [:activerecord, :errors, :messages]
+I18n.t :record_invalid, :scope => [:activerecord, :errors, :messages]
 </ruby>

 Additionally, both the key and scopes can be specified as dot-separated keys as in:

-I18n.translate :"activerecord.errors.messages.invalid"
+I18n.translate "activerecord.errors.messages.record_invalid"
