I don't know anything about Django, and I don't really understand what you are trying to do. Business logic is meant to be "straight into models". > So I was wondering about Rails3 ... seeing there's a new ActiveModel > abstraction of the ActiveRecord interface, can I use that to have the > desired effect? No. With this abstraction, validations are available for non ActiveRecord models, but the validations still have to be in the model. > Also, where can I find some good and up to date tutorials on Rails3 ? http://edgeguides.rubyonrails.org Not sure the guides are all up to date though. > 2) ORM lazyness > > I like that Django's ORM and in DBIx::Class, the resultsets > constructed are lazy.

There is no stable release of Rails 3 yet, as we are still at beta 3. But this new API is very much ready for use. -- Gael Muller -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
