I'm updating this older thread based upon my recent experience. This will not call strip on nils, fixnums, etc.

  before_save :strip_whitespace

  def strip_whitespaces     @attributes.each do |attr,value|       self[attr] = value.strip if value.is_a?(String)     end   end

Might also try...

      self[attr] = value.strip if value.respond_to?(:strip)

... to pick up things that aren't strings, but are string like.
