Interesting Things

  • Model#update_all is your friend if you're not yet on Rails 2.1

    Like 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!

    Hello, Model#update_all is indeed great, but it's Model#update_attribute that skips the validation checks (not update_attributes).

    Stijn - thanks for the catch. Now fixed.
