I am not exactly sure what is meant by CoC, Continuity of Code?
If that's the case, don't count on it because many things changed from
1.2 to 2.x
2.0 release notes
http://weblog.rubyonrails.org/2007/12/7/rails-2-0-it-s-done
2.3 release notes
http://guides.rubyonrails.org/2_3_release_notes.html
if you are determined to play along with an outdated book that uses an
outdated version of Rails, you might consider installing and using an
outdated version of Rails...
gem install rails --version 1.2.6 (I think is the command...going from
flaky memory) Then you would have to instruct rails to use a different
version (check out the 'rake --tasks' command)
or you can try to deduce the changes from the release notes offered
above.
