NAME Catalyst::Model::DBIC::Schema - DBIx::Class::Schema Model Class SYNOPSIS Manual creation of a DBIx::Class::Schema and a Catalyst::Model::DBIC::Schema: 1. Create the DBIx:Class schema in MyApp/Schema/FilmDB.pm: package MyApp::Schema::FilmDB; use base qw/DBIx::Class::Schema/; __PACKAGE__->load_classes(qw/Actor Role/); 2. Create some classes for the tables in the database, for example an Actor in MyApp/Schema/FilmDB/Actor.pm: package MyApp::Schema::FilmDB::Actor; use base qw/DBIx::Class/ __PACKAGE__->load_components(qw/Core/); __PACKAGE__->table('actor'); ... and a Role in MyApp/Schema/FilmDB/Role.pm: package MyApp::Schema::FilmDB::Role; use base qw/DBIx::Class/ __PACKAGE__->load_components(qw/Core/); __PACKAGE__->table('role'); ... Notice that the schema is in MyApp::Schema, not in MyApp::Model. This way it's usable as a standalone module and you can test/run it without Catalyst. 3. To expose it to Catalyst as a model, you should create a DBIC Model in MyApp/Model/FilmDB.pm: package MyApp::Model::FilmDB; use base qw/Catalyst::Model::DBIC::Schema/; __PACKAGE__->config( schema_class => 'MyApp::Schema::FilmDB', connect_info => [ "DBI:...", "username", "password", {AutoCommit => 1} ] ); See below for a full list of the possible config parameters. Now you have a working Model, accessing your separate DBIC Schema. Which can be used/accessed in the normal Catalyst manner, via $c->model(): my $actor = $c->model('FilmDB::Actor')->find(1); You can also use it to set up DBIC authentication with Authentication::Store::DBIC in MyApp.pm: package MyApp; use Catalyst qw/... Authentication::Store::DBIC/; ... __PACKAGE__->config->{authentication}{dbic} = { user_class => 'FilmDB::Actor', user_field => 'name', password_field => 'password' } "$c->model()" returns a DBIx::Class::ResultSet for the source name parameter passed. To find out more about which methods can be called on a ResultSet, or how to add your own methods to it, please see the ResultSet documentation in the DBIx::Class distribution. Some examples are given below: # to access schema methods directly: $c->model('FilmDB')->schema->source(...); # to access the source object, resultset, and class: $c->model('FilmDB')->source(...); $c->model('FilmDB')->resultset(...); $c->model('FilmDB')->class(...); # For resultsets, there's an even quicker shortcut: $c->model('FilmDB::Actor') # is the same as $c->model('FilmDB')->resultset('Actor') # To get the composed schema for making new connections: my $newconn = $c->model('FilmDB')->composed_schema->connect(...); # Or the same thing via a convenience shortcut: my $newconn = $c->model('FilmDB')->connect(...); # or, if your schema works on different storage drivers: my $newconn = $c->model('FilmDB')->composed_schema->clone(); $newconn->storage_type('::LDAP'); $newconn->connection(...); # and again, a convenience shortcut my $newconn = $c->model('FilmDB')->clone(); $newconn->storage_type('::LDAP'); $newconn->connection(...); DESCRIPTION This is a Catalyst Model for DBIx::Class::Schema-based Models. See the documentation for Catalyst::Helper::Model::DBIC::Schema for information on generating these Models via Helper scripts. CONFIG PARAMETERS schema_class This is the classname of your DBIx::Class::Schema Schema. It needs to be findable in @INC, but it does not need to be inside the "Catalyst::Model::" namespace. This parameter is required. connect_info This is an arrayref of connection parameters, which are specific to your "storage_type" (see your storage type documentation for more details). If you only need one parameter (e.g. the DSN), you can just pass a string instead of an arrayref. This is not required if "schema_class" already has connection information defined inside itself (which isn't highly recommended, but can be done) For DBIx::Class::Storage::DBI, which is the only supported "storage_type" in DBIx::Class at the time of this writing, the parameters are your dsn, username, password, and connect options hashref. See "connect_info" in DBIx::Class::Storage::DBI for a detailed explanation of the arguments supported. Examples: connect_info => [ 'dbi:Pg:dbname=mypgdb', 'postgres', '' ], connect_info => [ 'dbi:SQLite:dbname=foo.db', { on_connect_do => [ 'PRAGMA synchronous = OFF', ], } ], connect_info => [ 'dbi:Pg:dbname=mypgdb', 'postgres', '', { AutoCommit => 0 }, { on_connect_do => [ 'some SQL statement', 'another SQL statement', ], } ], Or using Config::General: schema_class MyApp::Schema::FilmDB connect_info dbi:Pg:dbname=mypgdb connect_info postgres connect_info AutoCommit 0 on_connect_do some SQL statement on_connect_do another SQL statement or schema_class MyApp::Schema::FilmDB connect_info dbi:SQLite:dbname=foo.db storage_type Allows the use of a different "storage_type" than what is set in your "schema_class" (which in turn defaults to "::DBI" if not set in current DBIx::Class). Completely optional, and probably unnecessary for most people until other storage backends become available for DBIx::Class. METHODS new Instantiates the Model based on the above-documented ->config parameters. The only required parameter is "schema_class". "connect_info" is required in the case that "schema_class" does not already have connection information defined for it. schema Accessor which returns the connected schema being used by the this model. There are direct shortcuts on the model class itself for schema->resultset, schema->source, and schema->class. composed_schema Accessor which returns the composed schema, which has no connection info, which was used in constructing the "schema" above. Useful for creating new connections based on the same schema/model. There are direct shortcuts from the model object for composed_schema->clone and composed_schema->connect clone Shortcut for ->composed_schema->clone connect Shortcut for ->composed_schema->connect source Shortcut for ->schema->source class Shortcut for ->schema->class resultset Shortcut for ->schema->resultset storage Provides an accessor for the connected schema's storage object. Used often for debugging and controlling transactions.
