Ruby on Rails

Hi, here are the steps that I performed:

a) rails restapp

b) cd restapp

c) ./script/generate scaffold Person name:string description:text

d) rake db:migrate

e) add the the following to the top of the routes.rb:

  map.root :controller => 'people'

f) ./script/server

g) go to the following address within your browser

  http://localhost:3000

h) click the 'New person' link and complete form

i) click the create button and you should see the following message:

ActiveRecord::RecordNotFound in PeopleController#show

Couldn't find Person with ID=0 RAILS_ROOT: /Users/conradwt/ruby.dir/projects/restapp

Application Trace | Framework Trace | Full Trace vendor/rails/activerecord/lib/active_record/base.rb:1375:in find_one' vendor/rails/activerecord/lib/active_record/base.rb:1358:infind_from_ids' vendor/rails/activerecord/lib/active_record/base.rb:537:in find' app/controllers/people_controller.rb:29:inshow' Request

Parameters:

{"id"=>"0"}

Show session dump

Response

Headers:

{"cookie"=>[], "Cache-Control"=>"no-cache"}

Next, it the save succeeds but the redirect fails because it's trying to redirect to /people/0. After further investigation, in the console:

BEGIN CONSOLE:

darnoc-desktop:restapp conradwt$ script/console Loading development environment (Rails 2.1.0)

a) person = Person.new

 The DL driver for sqlite3-ruby is deprecated and will be removed
 in a future release. Please update your installation to use the
 Native driver.
 #<Person id: nil, name: nil, description: nil, created_at: nil, updated_at: nil>

b) person.name = "Conrad"

 "Conrad"

c) person.description = "This is yet another test"

 "This is yet another test"

d) person.save

 true

e) person

 #<Person id: 0, name: "Conrad", description: "This is yet another test", created_at: "2008-08-12 23:00:27", updated_at: "2008-08-12 23:00:27">

END CONSOLE:

Next, from the above, the id field isn't being properly updated after the save and I'm seeing this with the following setup:

OS: Mac OS 10.5.4

Platform: PPC G5

Ruby Version: ruby 1.8.7 (2008-08-08 patchlevel 71) [powerpc-darwin9]

Rails Version: Rails 2.1.0

Furthermore, this problem doesn't exist for my laptop with the following setup:

OS: Mac OS 10.5.4

Platform: Intel Core 2 Duo

Ruby Version: ruby 1.8.7 (2008-08-08 patchlevel 71) [i686-darwin9]

Rails Version: Rails 2.1.0

Lastly, it appears to be an installation/configuration issue on the PowerMac G5 in regards to SQLite3 using Rails 2.1.0 becausse this issue doesn't appear when using MySQL on this platform with this environment configuration.
