Rails on Sun
Hi Everbody, I''ve got a potential idea for introducing Rails to my company. My only shot at this is to minimize what our Ops guys would have to install and configure to get this up and running. Right now, our servers are Solaris boxes and we are using Sun ONE as our web server. Anyone got Rails running in this environment? Also, has anyone got Rails talking to Oracle databases?

ActiveRecord: Behavior not doumented
Hello everbody, doing a #find(:first,an_id) with Rails 1.1.0 I expected that find returns the record which id mathches the given parameter an_id or nil if it couldn''t be found. This behaviour is documented on api.rubyonrails.org. But the find returns the first available object and not nil if an_id is not in the db. Is the doc on rubyonrails.org out of sync? Greetings, -- Daniel

one more try - ENV and FastCGI
Hi, I''m desperate, so I thought I''d try one more time in the hopes of getting a different audience. Basically. it boils down to this. Using CGI, the ENV hash is populated and is accessible from a model script. Using FastCGI, the ENV hash is empty. Can anyone explain how I can fix this?

long filenames always mangled under dos
I create a Bootdisk from Win98 with "sys a:" and the netsetup from the Microsoft FTP-server to have TCP/IP under DOS. I can map the shares from Samba to a drive with: "net use d: \\server\win98" The problem is that all long filenames are mangled, but not in the way DOS does it. The Folder "Program Files" does not become "Progra~1" but "Progr~4Z".
