Call super for self

Question

I have a 3rd party gem with extension for String class:

class String
  def to_url
    self.gsub /\s+/, '-'
  end
end

And I have my app trying to extend String class:

class String
  def to_url
    Russian.translit self
    super
  end
end

How do I call super (to replace spaces AND do transliteration) from my app? My code does super, but skips Russian.translit self.

Answer 1

There is no super to call. You should use alias_method

class String
  alias_method :old_to_url, :to_url
  def to_url
    Russian.translit(self).old_to_url
  end
end
