Working on a rails 3 app where I want to check if a translation exists before outputting it, and if it doesn't exist fall back to some static text. I could do something like:

if I18n.t("some_translation.key").to_s.index("translation missing")

But I feel like there should be a better way than that. What if rails in the future changes the "translation missing" to "translation not found". Or what if for some weird reason the text contains "translation missing". Any ideas?

Based on what you've described, this should work:

I18n.t("some_translation.key", :default => "fallback text")

See the documentation for details.
