Default Chapter 10

Just a note about the REST Web Service examples in Chapter 10, pgs 383-388:

If you're using Rails 2.3, and you download the Chapter 6 code (without authentication), you'll have to rename
and change
RAILS_GEM_VERSION = '2.2.2' unless defined? RAILS_GEM_VERSION
to match your Rails version.

another way to fix this is to run:
rake rails:update
I kept getting errors while trying to follow along in the book. It took me about 10 minutes to figure out these changes and to realize you should follow the CRUD sections in CRUD order. If you follow in the order presented in the book, you will have errors because there are no records in the database to read, assuming you've downloaded the code and started right away.

I may have been a bit hasty in following the examples, but this should help at least with the application_controller change in Rails 2.3.

Hi Jim,

thanks for your comment and for pointing out the version upgrade to fellow readers.

The book is best followed using Rails 2.2, even though last minute pointers for Rails 2.3 have been provided. For example, I point out the usage of the command rake rails:update to upgrade important files like application.rb at page 416, in the chapter dedicated to going into production.

Regarding the order, the project in Chapter 10 "consumes" the simple blog application developed in Chapter 6, as pointed out on page 384. By that chapter the reader will have already created sample articles, therefore the "Read" section of Chapter 10 wouldn't cause any errors. If you didn't follow the progression throughout the book, then yes, creating a couple of sample record progressing in the CRUD order is a valid alternative.
