Hi, I''m a Java/J2EE developer that is new to Rails. I''ve read through most of _AWD with Rails_ so that I have a basic understanding of what Active Record can do. I''ve also done a bit of reading up on the switch to RESTful controllers in Rails 2.0. I''m developing an app in Rails 2.0.2 with Ruby 1.8.6. I noticed that static scaffolding generates logic in the controllers that modifies the database such as @myActiveRecord.save (likewise for update_attributes and destroy). The Rails API saith that save and destroy will be wrapped in a transactional context, but what about update? Is that automatically transactional? If not, then to this Java developer''s eyes, this seems to be a mistake.

Save, destroy and update_attributes are in transactional method. If there''s an error while executing database it would be rolled back, the error can be handled by using errors.add(:attribute, "your error message here"). But you can use locking method for more secure transaction it would be nice transaction. like a NameModel.find(params[:id], :lock=> true), it will hold other transactions which is wanting to update or access NameModel.find(params[:id]. Ruby has also ActiveRecord Transaction, like : ActiveRecord.transaction do ... end or YourModelName.transaction do ... end Reinhart http://teapoci.blogspot.com -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
