Ruby On Rails：用于其他语言的复数形式

I am building apps for a non-english audience. Right now, I use english nouns to name my models, yet I prefer to use native dutch ones. As the convention uses the plural of the class name for tables, I assume it is the pluralize method inside Rails (where it resides, I wouldn't know). How can I change the pluralize method and where is it located? Would this break Rails? I am building apps for a non-english audience.
