Re: [Radiant] Radiant and IBM DB2
Hi Anton, Thanks for your reply. The Ruby on rails book - the Pickaxe book - discusses how to use RoR with legacy databases. I'd recommend looking at that. You mean the Agile Web Development with Rails book? In short, the answer is YES, but you need to have some other database to act as a 'shim' of some kind. Could you explain that a bit further?

Re: [Radiant] Radiant and IBM DB2
Hi Davide, Wow, That's great information! Thank you so much. You know, I've just finished setting up DB2 on my Mac and I've just gotten my first Radiant app on DB2 up and running. That's really cool. I've written a short article about it here: http://blog.springenwerk.com/2009/01/ibm-db2-on-mac-with-ruby-rails-and.html Once again, thank you! - Johannes On Tue, Jan 13, 2009 at 1:05 PM, Panizzolo, Davide davide.panizz...@unitn.it wrote: Hi Johannes, in our Department we developed a Radiant application using DB2. We created a radiant application using the DB2 adapter and then we created some extensions to work with the DB2 legacy database. The main difficulty was that the DB2 adapter has some significant limitation (for example the rename_column do not work) and this was a problem especially for migrations. You need to start with the final version of the schema of your db, since changes are difficult. Of course this is a general RoR - DB2 problem. Except for this problem the application works fine.

Ok, I see. Yes, the missing id column problem will have to be solved. I think Dr. Nic has written a plugin to support multi-column primary keys. That might be what I'll need. - Johannes -- Hackers: Self-righteous crackers -- CSO Magazine's The Devil's Infosec Dictionary ___ Radiant mailing list Post: Radiant@radiantcms.org Search: http://radiantcms.org/mailing-list/search/ Site: http://lists.radiantcms.org/mailman/listinfo/radiant -- http://blog.springenwerk.com ___ Radiant mailing list Post: Radiant@radiantcms.org Search: http://radiantcms.org/mailing-list/search/ Site: http://lists.radiantcms.org/mailman/listinfo/radiant

The customer has a legacy DB2 database. Replacing it is not an option for the customer. So my question is: can I use Radiant with DB2? Does anyone have any experience doing this?
