[Patch for Review] dirty methods on attribute aliases

Rails currently doesn’t support the dirty methods for an attribute alias’.

i.e. if you setup an alias called title (alias_attribute :title, :name) then title_changed? isn’t defined.

Rich has written a simple patch with test so the dirty methods are defined for attribute alias’s -> http://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/812 and it’s received a couple of +1’s now.



Could've sworn I saw a post like this before.

I dropped it into the rails-talk list (not the core list) on Sunday/Monday.
