Model#update_all is your friend if you’re not yet on Rails 2.1
Model#update_attribute for each attribute,
#update_all will save direct to the database, bypassing validation, updating only the columns you specify. In Rails 2.1, with partial model updates, you may not need this. But if you’ve not yet upgraded your application, then give
#update_all a try.
Update: fixed per comment.
Model#update_attribute does not validate. Thanks for the catch!
