Ruby on Rails I18n - Internationalization Pluralization
Example
You can let I18n handle pluralization for you, just use count argument.
You need to set up your locale file like this:
# config/locales/en.yml en: online_users: one: "1 user is online" other: "%{count} users are online" And then use the key you just created by passing the count argument to I18n.t helper:
I18n.t("online_users", count: 1) #=> "1 user is online" I18n.t("online_users", count: 4) #=> "4 users are online"
