Interpolation in I18n array

Question

I\'m using arrays in a locale file to be able to generate blocks of text in various output methods (ActionMailer templates, Prawn documents, HAML templates) that are locale-spec

Answer 1

I think such thing is not supported natively in i18n gem, but it's doable using some meta-programming magic.

In an initializer (say, config/initializers/i18n.rb) add the following

I18n.backend.instance_eval do
  def interpolate(locale, string, values = {})
    if string.is_a?(::Array) && !values.empty?
      string.map { |el| super(locale, el, values) }
    else
      super
    end
  end
end
