Answer 1

I never used Devise, but I think the "taken" message is an ActiveRecord error message (not specific to the Devise gem). If you plan on using a non-english locale I would advice you to change the default locale instead of adding non-english content to the EN one.

    errors:
      messages:
        taken: "este %{model} ya sido utilizado"
