connection

v2.1.0 - Show latest stable - Class: ActiveRecord::Base

connection()

public

Returns the connection currently associated with the class. This can also be used to "borrow" the connection to do database work unrelated to any of the specific Active Records.

# File activerecord/lib/active_record/connection_adapters/abstract/connection_specification.rb, line 73
      def connection
        if defined?(@active_connection_name) && (conn = active_connections[@active_connection_name])
          conn
        else
          # retrieve_connection sets the cache key.
          conn = retrieve_connection
          active_connections[@active_connection_name] = conn
        end
      end

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.
