No database data showing up no warning message

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This tutorial is really out of date.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?

Most of the tutorials are really out of date. Rails has moved on quite
a bit
since version 2.0. I read the tutorials on the Akita on Rails site.
