Rails 2.0.2 and Agile Web Development 2ed

Hello all, someone know where do i find documentation about how to
learn ruby on rails 2.0.2 with examples?
At now, i am reading "Agile Web Development with Rails 2ed." but i
have had a lot of problems with my version of rails (2.0.2).
Thanks a lot.

Regards

maybe not the answer you were looking for but rails 2.0.2 was just
released and its not radically different to previous versions. My
point being the articles you find online for earlier versions are
still applicable minus a few deprecated values (just search google for
those, e.g http://www.slashdotdash.net/articles/2007/12/03/rails-2-upgrade-notes)

As for how to learn, believe it or not i found the best way was to
think of something to do, and then lookup examples online. Agile i
have heard is a good start. I think the best thing to keep in mind
when learning from a book is that you are not getting the whole story.
There is a reason why some things are plural, some things are hashed,
etc. Good luck. The more examples you see, the more you will put 2 and
2 together.

I put a post on my blog about exactly this issue. Sorry about the shameless plug, but it's way easier than typing it again and again on the mailing list.

If you find any errors, feel free to comment.

Another suggestion that might make your learning easier is that you
could go ahead and install the version of Rails used in the AWDWR book
so you can follow along with their examples. Then after you are
comfortable enough with that go out to www.peepcode.com and grab their
PDF on the new features in Rails 2.0.

You should be able to set the version to use in the environment.rb so
you can have both versions of Rails in your system.
