Submit button helper with I18n.t

Question

I want to write a helper for a submit button, that takes in account the action (create or update) to get the right translation. Here they are :

Answer 1

def submit_button(model)
  if model == nil
    I18n.t("submit.create.#{model}")
  else
    I18n.t("submit.update.#{model}")
  end
end

The %{} is used in en.yml file when you send a local variable from helper or view.
