NAME

SPOPS::Tool::DBI::Datasource -- Embed the parameters for a DBI handle in object configuration

SYNOPSIS

 my $spops = {
   myobject => {
     class      => 'My::Object',
     rules_from => [ 'SPOPS::Tool::DBI::Datasource' ],
     dbi_config => { dsn => 'DBI:mysql:test',
                     username => 'kool',
                     password => 'andthegang' },
     ...
   },
 };
 SPOPS::Initialize->process({ config => $spops });
 my $object = My::Object->fetch( 'celebrate' );

DESCRIPTION

This rule allows you to embed the DBI connection information in your object rather than using the strategies described elsewhere. This is very handy for creating simple, one-off scripts, but you should still use the subclassing strategy from SPOPS::Manual::Cookbook if you will have multiple objects using the same datasource.

You can specify the following items in the configuration:

• "dsn": The DBI DSN, or the first entry in the normal DBI "connect" call.
• "username": Username to connect with
• "password": Password to connect with
• "trace": Trace level to use (0-5, see DBI for what the levels mean)

METHODS

behavior_factory( $class )

Generates a behavior to generate the datasource retrieval code during the 'manipulate_configuration' phase.

datasource_access( $class )

Generates the 'global_datasource_handle()' method that retrieves an opened database handle if it exists or creates one otherwise.

BUGS

None known.

TO DO
