How to use two languages ​​in the application at the same time?

Question

Ruby on Rails

Good afternoon! The question is: can I use 2 language files at the same time in one application using I18n.t?
Let me explain with an example: there is a locale RU (set "by default") and there is a locale EN (optional). There is, for example, the following line in the code: This line will pull out the string 'ru.hello_world' from the RU locale. But hypothetically, a situation may arise that there will be no hello_world line in the file with the RU locale. In this case, as a solution for myself, I see loading the missing lines from the EN locale. Those. the logic of the program: if there is no string in the RU locale, then I load the string from the EN locale. Is it possible to do so? Unfortunately, if you use the following code:
$s = I18n.t('hello_world')

$s = I18n.t('hello_world', :default=>I18n.t('en.hello_world'))

then if there is no string in RU, an attempt is made to load the string 'ru.en.hello_world' from the RU locale.

You need config.i18n.fallbacks
In production it is installed automatically:

# Enable locale fallbacks for I18n (makes lookups for any locale fall back to
  # the I18n.default_locale when a translation cannot be found).
  config.i18n.fallbacks = true
