I read several tutorials and tried with them. Finally, I adopted the sample used inhttp://www.oracle.com/technology/pub/articles/haefel-oracle-ruby.html with mysql because it is more up-dated.
This tutorial is really out of date. Rails has moved on quite a bit since 2006. I would suggest looking at the tutorials on the Akita on Rails site.
I executed "http://127.0.0.1:3000/categories/show" or "http://127.0.0.1:3000/categories/list", the error messages came up. /usr/lib/ruby/gems/1.8/gems/activerecord-2.0.2/lib/active_record/base.rb:1267:in `find_one' /usr/lib/ruby/gems/1.8/gems/activerecord-2.0.2/lib/active_record/base.rb:1250:in `find_from_ids' /usr/lib/ruby/gems/1.8/gems/activerecord-2.0.2/lib/active_record/base.rb:504:in `find' app/controllers/categories_controller.rb:16:in `show'
What does line 16 of your categories_controller.rb file say as this is where the error is being thrown?
