Hi,
Can any one help me? I’m using Ubuntu and trying to connect to an oracle
database using oracle_enhanced adapter connection, but keeps getting
following error:
/usr/lib/ruby/gems/1.8/gems/activesupport-2.1.0/lib/active_support/dependencies.

class Connect < ActiveRecord::Base
set_table_name “changelog”
end
current_db = Connect.find(:first, :order => ‘applied_dttm DESC’)
Any ideas from any genius?
Thanks!
