hi everyone, I have this case where I need to check some records in the database of a specific data condition every 5 seconds and do some business logic if this scenario is true.

Hi, I''m using a room model throughout my code. I keep doing the following: @rooms = Room.find(:all, :order => ''buildings.name, room_number'', :include => :building) I have to copy this into several of my controllers and I feel that I''m violating the DRY principle. Can I set this as the default order in my model? If so, how would I do that? Thanks,

Hi CAS is a centralized authentication service, and the cas_auth filter can be installed to automatically make your web application authenticate against a CAS server. The SVN path to the plugin is http://svn.ki.se/rails/plugins/cas_auth and a homepage with some information can be found at http://opensource.ki.se/casauth.html For use, just install the plugin in your application and set

The server has two 120GB hard drives, one of which will just be for nightly backups of the other. I don''t intend to have any untrusted user accounts on the server. The server will be dedicated to my own applications. I''ll want to support lots of www
