Current Database Name

cracell · Aug 19, 20083 thanks

The MySQL database adapter extends this and allows you to call

ActiveRecord::Base.connection.current_database

to get the current databases name. Useful when you are actively changing the database you are connected to and sometimes need to check the current one.
