ruby script/plugin install http://railsexpress.de/svn/plugins/sql_session_store/trunk/

Step 1
=========

If you have generated your sessions table using rake db:sessions:create, go to Step 2

If you're using an old version of sql_session_store, run

    script/generate sql_session_store DB

where DB is mysql, postgresql or oracle

Then run

    rake migrate

or

    rake db:migrate

for edge rails.

Step 2
=========

Add the code below after the initializer config section:

    ActionController::CgiRequest::DEFAULT_SESSION_OPTIONS.
      update(:database_manager => SqlSessionStore)

Finally, depending on your database type, add

    SqlSessionStore.session_class = MysqlSession

or

    SqlSessionStore.session_class = PostgresqlSession

or

    SqlSessionStore.session_class = OracleSession

after the initializer section in environment.rb

Step 3 (optional)
===============

If you want to use a database separate from your default one to store your sessions, specify a configuration in your database.yml file (say sessions), and establish the connection on SqlSession in environment.rb:

   SqlSession.establish_connection :sessions
