Ruby on Rails latest stable (v5.2.3) - 0 notes - Superclass: ActiveRecord::ConnectionAdapters::AbstractAdapter

Class deprecated or moved

This class is deprecated or moved on the latest stable version. The last existing version (v1.2.6) is shown here.

In ADO mode, this adapter will ONLY work on Windows systems, since it relies on Win32OLE, which, to my knowledge, is only available on Windows.

This mode also relies on the ADO support in the DBI module. If you are using the one-click installer of Ruby, then you already have DBI installed, but the ADO module is NOT installed. You will need to get the latest source distribution of Ruby-DBI from http://ruby-dbi.sourceforge.net/ unzip it, and copy the file src/lib/dbd_ado/ADO.rb to X:/Ruby/lib/ruby/site_ruby/1.8/DBD/ADO/ADO.rb (you will more than likely need to create the ADO directory). Once you’ve installed that file, you are ready to go.

In ODBC mode, the adapter requires the ODBC support in the DBI module which requires the Ruby ODBC module. Ruby ODBC 0.996 was used in development and testing, and it is available at http://www.ch-werner.de/rubyodbc/
