In Rails 2.x, calling touch on an ActiveRecord model would update the
''lock_version'' on the model, if it were present.
It would produce something like this in SQL:
UPDATE `foo` SET `updated_at` = ''2010-07-23 10:44:19'',
`lock_version''
= 2 WHERE ''lock_version'' = 1
This would ensure that your optimistic locking policy will be followed
should another concurrent update occur on that row in your database.
Rails 3 no longer updates the ''lock_version'' column through
the touch
method. I preferred the Rails 2 behaviour, I was wondering if anyone
knew the reasoning behind this change?

C.
