UPDATE: Everything works now. Turns out I had a plugin installed that monkey patched the SQL Server Adapter. This plugin was from an older version of Rails, and the Rails 2.0 adapters now extend from AbstractAdapter. Fixing the parent class in my plugin monkey patch (to extend from AbstractAdapter) fixed this up and now I no longer get the error.

I just installed the SQL Server Adapter Gem from gems.rubyonrails.org for my new Rails 2.0 project:


gem install activerecord-sqlserver-adapter --source=http://gems.rubyonrails.org


When I attempt to use it, I receive this error message:

TypeError: superclass mismatch for class SQLServerAdapter
        from /var/lib/gems/1.8/gems/activerecord-sqlserver-adapter-1.0.0/lib/active_record/connection_adapters/sqlserver_adapter.rb:190
        from /usr/lib/ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require'
        from /usr/lib/ruby/1.8/rubygems/custom_require.rb:27:in `require'

        from /home/sladd/development/workspace/DSES2/vendor/rails/activerecord/lib/../../activesupport/lib/active_support/dependencies.rb:342:in `new_constants_in'

Any ideas? My database.yml looks like this:

development:
  adapter: sqlserver
  mode: odbc
  dsn: dses_rollup
  username: sa

Has anyone successfully installed the new SQL Server adapter as a gem into a Rails 2.0 project?

I’ve asked the Ruby on Rails Talk Google Group, so we’ll see if that turns up any help.
