Hello, Below is the message explaining where I stand.. Then you can answer either on the rails list, personally or to the ruby list: http://groups.google.com/group/comp.lang.ruby/browse_frm/thread/73205c23336a89d2/4b547ab8e66a94b7#4b547ab8e66a94b7 I apologize if this is some kind of cross-posting, but I figured out that maybe I''d have more success posting this question to the rails list than on the ruby one. Thanx for any help! Greetings. -- Newsgroups: comp.lang.ruby From: sjall...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org - Find messages by this author Subject: Re: database.yaml config for DB2 (and other DBMSs..) Ok, I''ve found and tried the following: development: adapter: db2 database: test_development host: my_hostname username: my_usrname password: my_pwd Then, "RUBY SCRIPT/GENERATE MODEL TABLE_NAME" where TABLE_NAME is a db2 object in my *CURLIB But the result is: C:\TEST>ruby script/generate model STSPAP c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.12.1/lib/active_record/connection_ adapters/abstract/connection_specification.rb:58:in `establish_connection'': data base configuration specifies nonexistent db2 adapter (ActiveRecord::AdapterNotFo und) from c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.12.1/lib/active_recor d/connection_adapters/abstract/connection_specification.rb:50:in `establish_conn ection'' ..etc etc... So, thanx for any hint about the adapter (isnt'' it included with Rails??), and about how to "choose" which table I want to generate a model for, according to the specific architecture of AS/400 systems (library/file and then member). Greetings.
