Hi all, Is there an easy way to not lose the file field input from the user after a validation error? It pisses people off to have to choose their files again just because some other field didn''t pass a validation. I''ve googled this and just haven''t come up with much of anything. Thanks.

Hey Everyone. First day diving in to ROR and Ruby... My question is how do you define methods with in the model class and/or should I even be doing this?

Hi, I've had NUT 2.6.1 on OpenIndiana working with a Tripp-Lite ECO550. I've been playing around with the config files a little bit, and I must have done something that messed up the demon. I now get wiley$ pfexec /opt/nut/sbin/upsd -DD Network UPS Tools upsd 2.6.1 0.000000 listening on 127.0.0.1 port 3493 0.000486 listening on ::1 port 3493 0.001279 Can't connect to

What's the best way to increment a numeric variable in the dial plan? I tried this... exten => s,1,Set(mainLoop=${MATH(${mainLoop}+1)}) but that converts it to a floating point number (WHY???), so I end up with 1.0000, which later on means I have to perform string manipulation to get rid of the .0000.

I've used NUT successfully for monitoring many different brands of UPS, but this one has me stumped. It has the same manufacturer ID and Product ID as older supported MGE-type Eaton UPS's, but has trouble talking. I tried Ubuntu's repo NUT, and it logs a Connecting to UPS message every few seconds forever, but never really succeeds (or says it fails). Different failure mode after

Hi! It seems that migration doesn''t use single transcation to execute the needed migrations for the database upgrade, so if I have database at version 5, and I wrote some migrations 6..10, and error occurs while executing migration 7, the database stays in state 6? I also think that migration taks could use some more verbosity, for example if migration fails, there''s no

Hello, I am trying to get nut running on a Windows 2012 R2 server (x64). I am using the MSI release of 2.6.5-3. The attached UPS is an APC xs1500 (model bx1500g).

I’m launching a rails website, the app is written and works, undoubtedly it’ll be an unmitigated disaster when I launch but none the less I thought I’d least attempt to give myself the best chance of success by asking all the gurus here for some advice – pre launch advice if you like. In an ideal world I’d spend days and hours on all of these things and get it absolutely spot on, but as we all

Hi all, I''ve been working on the win32-pipe library (again) and I''ve reworked the interface. Instead of Pipe.new_server or Pipe.new_client, there''s now a base Pipe class, with Pipe::Server and Pipe::Client subclasses. You can find the latest code in the CVS repo. Oh, and you''ll need to update your windows-pr library with the latest from CVS if you want to

I apologise if this is not the appropriate list for the following issue, but... Is it possible to upgrade the Linux kernel on a kickstart CD? I've changed the vmlinuz and initrd.img files in the isolinux directory from the distro's ISO image; so kernel 2.6.32-504.3.3.el6.i686 now boots from a DVD, and loads the appropriate modules and firmware from the stage 1 initrd.img.
