Help with Scaffolding deprecation on Rails 2.2.2

I am reading “Agile Web Development with Rails, 2nd Edition”, which is based on 1.2.6. However, on my Leopard based iMac, I was running Rails 2.2.2.

When I got to the part with associating a scaffold to my :products (located on the bottom of page 67), it outputted a No Scaffold method error (because scaffolds are not included in 2.2.2).

After searching some web sites, particularly <http://www.ruby- forum.com/topic/137274>, I tried to install 1.2.6 by issuing: gem install rails—version 1.2.6—include-dependencies.

This worked correctly, but when I still type check the current version from bash it states:

Rails 2.2.2

I then went into my app’s config/environment.rb file and set RAILS_GEM_VERSION to 1.2.6.

When I tried to re-start the WEBrick server, I got the following error:

=> Booting WEBrick… ./script/../config/../config/environment.rb:46: undefined method `time_zone=’ for #<rails::configuration:0x11600c0> (NoMethodError) from /Users/untz/.gem/ruby/1.8/gems/rails-1.2.6/lib/initializer.rb: 45:in `run’ from ./script/../config/../config/environment.rb:13

On line 46, on my WEBrick server, this is what is set:

config.time_zone = ‘UTC’

Question(s):

(1) Should I stick with learning Rails 2.2.2 and upgrade to Ruby 1.9?

(2) Is the 2nd Edition of this book now deprecated or is there a workaround to my problem?

(3) Any good resources on learning the new version of Rails?

Happy programming!

just remove that - it's an option only available with rails >= 2.1 (which was the case when you generated the app, but now you're trying to run with an older version)

Question(s):

certainly don't skip to ruby 1.9 unless you are using a version of rails ready for it (which right now means rails 2.3rc1). I would stick to 2.2.2 if you're still learning

Fred,

perhaps creating the app with the version you need will help avoid this and other issues. You can do it by specifying the version enclosed in underscores before passing the name of the new app:

   rails _1.2.3_ mynewapp
