Hi!
I''m just writing an application that stores some data withy
ActiveRecord in a database. In this context I''d love to have every
state of an object stored. Could it be possible to add some kind of
version-control to ActiveRecord?
I don''t have much experience with ruby, but this should be rather (?)
simple. One could add an `version`-attribute and an
''internal_id''.
Every find-method should then return the latest version of an object.
Furthermore, a ''deleted''-column needs to be added.
Has anyone thought of this before? Ist this implemented somewehere?
Or is the idea plain stupid?
Keep on rollin''

Then you create an after_save callback that will add a new entry to the history table after the object is saved. That way your primary table won''t get cluttered with the version data. As a matter of fact, there''s something along these lines already in the works [1], to provide a generalized framework for versioning. //jarkko [1] http://wiki.rubyonrails.com/rails/show/ActsAsVersioned> > Keep on rollin'' > Peter > _______________________________________________ > Rails mailing list > Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org > http://lists.rubyonrails.org/mailman/listinfo/rails > >_______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails
Hi Take a look at http://wiki.rubyonrails.com/rails/show/ActsAsVersioned That should do what you want.

Though, this requires you to run on edge rails. -- rick http://techno-weenie.net
