Ruby on Rails

Hi

I'm trying to use the activerecord-sybase-adapter to be able to use ASE with my rails applications.
But, I am struggling...

I followed (most of) the steps on this informative page:
http://trevoke.net/blog/2009/09/11/connecting-to-sybase-with-rails-on-windows-xp/

Initially I had Rails 2.3.5 installed.
I copied the "Ruby Sybase files" as instructed and the Sybase dll files as well, and I installed activerecord-sybase-adapter (1.0.0.9250).
The Sybase environment I already have on my office computer, so it should be allright.
I don't have the mentioned JDBC_HOME setting or the classpath setting, but I'm using Open Client, so should there be any need for the JDBC settings?

Ok, things looked promising, and I started creating a test rails app.

rails testapp

I then edited the database.yml to fit Sybase ASE
development:
  adapter: sybase
  database: testdb
  username: username
  password: password
  host: sauron

The host, sauron, is defined in the sql.ini file.

Running rake db:create tells me that the database testdb already exists. (true)

ruby script\generate scaffold person first_name:string last_name:string     WORKS OK
rake db:migrate --trace    FAILS!
(in C:/work/ror/testapp)
** Invoke db:migrate (first_time)
** Invoke environment (first_time)

so... looks like something's missing here. In mysql_adapter.rb there is a select_row function, but not in the sybase_adapter.rb.

I tried downgrading Rails to 2.1.0 because I read somewhere that the activerecord-sybase-adapter perhaps was not working for the latest Rails releases, but got only a slightly different error message:

rake aborted!
select_rows is an abstract method
c:/prg/ruby/lib/ruby/gems/1.8/gems/activerecord-2.1.0/lib/active_record/connection_adapters/abstract/database_statements.rb:34:in `select_rows'

...

Anyone has an idea?

Best regards,
Rolf
