Catalyst::Model::DBI - DBI Model Class

       Copyright (c) 2005 - 2012 the Catalyst::Model::DBI "AUTHOR" as listed above.

       This is the "DBI" model class. It has been rewritten to use DBIx::Connector since it's internal code that
       deals with connection maintenance has already been ported into there. You now have two options for doing
       custom models with Catalyst. Either by using this model and any related modules as needed or by having
       your custom model decoupled from Catalyst and glued on using Catalyst::Model::Adaptor

       Some general rules are as follows. If you do not wish to use DBIx::Connector directly or DBI and setup
       connections in your custom models or have glue models, then use this model. If you however need models
       that can be re-used outside of your application or simply wish to maintain connection code yourself
       outside of the Catalyst, then use Catalyst::Model::Adaptor which allows you to glue outside models into
       your Catalyst app.

       new Initializes DBI connection

       $self->connection
           Returns the current DBIx::Connector connection handle.

       $self->dbh
           Returns the current database handle.

       $self->connect
           Connects to the database and returns the handle.
