I''ve completed the chapter on Internationalization successfully, but found out just recently that the "Who Bought" function produces an error page that looks very ugly when someone enters a product ID that does not exist. My preference would be to design the app to have a list of hyperlinks presented when you visit the URL, http://localhost:3000/info/ that describes the list of

Hi, My name is Paul Kristoff and I am rather new to rails. I am trying to use Capistrano for the first time and am rather confused. My confusion boils down to the :repository variable in the deploy.rb file. Is this supposed to point to where your code is currently being stored?

I just tried setting up a simple Rails app, after updating to the 1.1RC1 version of Rails. Generating a simple scaffold worked fine, and WEBrick started fine with script/server.

Greetings, With all the press concerning the 'almost 1.0' release of vorbis; I see a lot of messages floating around as 'now 1.0, and -soon- it will include joint-stereo, Wavelets, low-bitrate, peeling, etc. etc.' Before I start 'advocating' vorbis and tell everybody what it all can do; is there actually a date or some other planning when all those

I just installed MySQL and its drivers on a Mac OS X Leopard. When I issued my rails command to build a new app, then issued the script/ server command and connected to my localhost:3000 in the browser, I saw the following problem with MySQL.

I ran the usual "sudo gem install rails --include-dependencies" to upgrade and now my development environment is all out of whack. I suspected MySQL, but I''ve already made sure I was using the

Hi all, Our section at work is looking at buying a high-powered computer (32 Gb RAM, 64-bit) to be able run models on large datasets and have more processing power for the software we commonly use. We mostly use R to fit GLMs and GAMs. Our department uses Windows as the standard OS (we are upgrading to Vista in the next few months) and so most people would be in favour of having the same OS on
