I have some controller code that uses the 'httpdate' method of a 'created_on' field from my database. I'm running Rails on the Edge. My development environment is Windows XP, my 'production' environment is Debian Linux. When I upgraded my 'production' machine for the first time in a month, I start getting an error that 'httpdate' is not a method of 'created_on'. This part of the code is unchanged. This method is defined in 'time.rb' as part of the Ruby distribution. If I add "require 'time'" to my controller, all is well again. I can find no "require 'time'" line in my vendor Rails code. Some questions: 1. Why did my original code work with earlier versions of Edge Rails? 2. Why did my original code work on Windows but not Linux? 3. Is this a production vs development issue? 4. What else is different that I may not find until I'm in production? 5. Is it my responsibility to do the "require" here, or is it reasonable to expect Rails to do this for me?
