store_translations(locale, data, options = EMPTY_HASH)

Stores translations for the given locale in memory. This uses a deep merge for the translations hash, so existing translations will be overwritten by new ones only at the deepest level of the hash.

lookup(locale, key, scope = [], options = EMPTY_HASH)
click to toggle source
Looks up a translation from the translations hash. Returns nil if either key is nil, or locale, scope or key do not exist as a key in the nested translations hash. Splits keys or scopes containing dots into multiple keys, i.e. currency.format
is regarded the same as %w(currency format)
.
