Quick and dirty way to spot non-localized strings in a Rails app page

stupid_t.rb

# config/initializers/stupid_t.rb
# Any text that doesn't appear as "localized" isn't localized
module ActionView::Helpers::TranslationHelper
  def t(*args)
    result = I18n.t!(*args)
    if result.respond_to?(:map)
      result.map { |r| "localized" }
    else
      "localized"
    end
  end
end
