Problem with :touch in belongs_to

rubyonrails-talk

I've read in rails api that there is a touch parameter and I want to use it in my application. I have something like that class User < ActiveRecord::Base   has_many :phones

  after_update :updated

  def updated      ...   end end

class Phone < ActiveRecord::Base   belongs_to :user, :touch => true end

I want that every change of any phone number would change User updated_at and also call user after_update callback.

But when I add :touch parameter I get error that looks like:

ArgumentError: Unknown key(s): touch   from /Library/Ruby/Gems/1.8/gems/activesupport-2.3.2/lib/ active_support/core_ext/hash/keys.rb:47:in `assert_valid_keys'   from /Library/Ruby/Gems/1.8/gems/activerecord-2.3.2/lib/active_record/ associations.rb:1506:in `create_belongs_to_reflection'   from /Library/Ruby/Gems/1.8/gems/activerecord-2.3.2/lib/active_record/ associations.rb:994:in `belongs_to'   from (eval):3:in `belongs_to'   from /Users/arkadiuszmlynarczyk/TapConference/app/models/phone.rb:2

It's not in rails 2.3.2.
