rails3 session配置

Use the database for sessions instead of the cookie-based default, which shouldn't be used to store highly confidential information

Create the session table with

1.rake db:sessions:create  

Run the migration

  
rake db:migrate  

Make sure you also tell rails to use ActiveRecord to manage your sessions too.
