command

gem install rails --version 1.2.6 --include-dependencies

Now i am getting the error after starting the server

ruby script/server

Regenerate your application with rails 1.2.6 (rails _1.2.6_ myapp).
the one generated by rails 2.0 references stuff that doesn't exist in
1.2.6

step 1: Have a look in to this link, if it doesn't happen better
        switch over to step 2.

http://leonardoborges.com/writings/2007/12/21/rails-20-scaffold/

step 2: Try the same with rails 1.2.3, Dynamic scaffolding is no longer
available in rails 2.0.

Simply installing the 1.2.6 gem doesn't magically make your rails
command use 1.2.6, if you have 2.x installed. It'll always use the
latest version unless you specify otherwise. What you need to do is
issue the following command:

     rails _1.2.6_ depot

That should make it so you can follow the tutorials without any issues
related to changes from 2.x that might not be compatible with the book
you're reading from. You also need to make sure you do this without
overwriting your existing depot 2.x rails app -- I'm not sure what'd
happen if you did so (it might work but it might not). To avoid any
headaches I'd delete your depot project, and regenerate the 1.2.6
project from scratch.
