explicitly tell into what language to translate

Question

I have as usual my translation files in locales.

Now I have an invitation mail in various languages.

I want the user to select in what language the mail should be sent, because it's not about the language of the operating user, it's about the language the mail receiver should read.

Is there a way to tell rails explicitly what language to pick, like t(:my_string, :en)?

The goal is, to have it temporary translated for only one single call of t.

This is what I need, to tell within the t() command, what language is to be used.

Answer 1

It's possible to pass :locale option to t method:

  t :my_string, locale: :de

Answer 2

I think you will explicitly need to set proper language to I18n.
You can use: I18n.locale = :en to set language you need.
