NAME¶
Catalyst::Model::DBI - DBI Model Class
SYNOPSIS¶
# use the helper to create a model for example
perl script/myapp_create.pl model MyModel DBI dsn username password
# lib/MyApp/Model/DBI.pm
package MyApp::Model::DBI;
use base 'Catalyst::Model::DBI';
__PACKAGE__->config(
dsn => 'DBI:Pg:dbname=mydb;host=localhost',
username => 'pgsql',
password => '',
options => { AutoCommit => 1 },
loglevel => 1
);
1;
# or load settings from a config file via Config::General for example
# in your myapp.conf you could have
name MyApp
<Model::MyModel>
dsn "DBI:Pg:dbname=mydb;host=localhost"
username pgsql
password ""
<options>
AutoCommit 1
</options>
loglevel 1
</Model>
# note that config settings always override Model settings
# do something with $dbh inside a controller ...
my $dbh = $c->model('MyModel')->dbh;
# do something with $dbh inside a model ...
my $dbh = $self->dbh;
#do something with DBIx::Connector connection inside a controller ...
my $connection = $c->model('MyModel')->connection;
#do something with DBIx::Connector connection inside a model ...
my $connection = $self->connection;
DESCRIPTION¶
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.
METHODS¶
- 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.
