my $schema = $model->schema( 'foo' );

my $id = $schema->create( $data );
my $count = $schema->delete( $id );
my $count = $schema->delete( $where );
my $count = $schema->set( $id, $data );
my $count = $schema->set( $where, $data );

my $item = $schema->get( $id );
my ( $items, $total ) = $schema->list( $where, $opts );

DESCRIPTION

NOTE: This module is experimental and its API may change before Yancy v2!

Yancy::Model is a framework for your business logic. Yancy::Model contains a number of schemas, Yancy::Model::Schema objects. Each schema contains a number of items, Yancy::Model::Item objects.

For information on how to extend this module to add your own schema and item methods, see Yancy::Guides::Model.

ATTRIBUTES

backend

A Yancy::Backend object.

namespaces

An array of namespaces to find Schema and Item classes. Defaults to [ 'Yancy::Model' ].

log

A Mojo::Log object to log messages to.

METHODS

find_class

Find a class of the given type for an object of the given name. The name is run through "camelize" in Mojo::Util before lookups.

unshift @{ $model->namespaces }, 'MyApp';
# MyApp::Schema::User
$class = $model->find_class( Schema => 'user' );
# MyApp::Item::UserProfile
$class = $model->find_class( Item => 'user_profile' );

If a specific class cannot be found, a generic class for the type is found instead.

# MyApp::Schema
$class = $model->find_class( Schema => 'not_found' );
# MyApp::Item
$class = $model->find_class( Item => 'not_found' );

read_schema

Read the schema from the "backend" and prepare schema objects using "find_class" to find the correct classes.

schema

Get or set a schema object.

$model = $model->schema( user => MyApp::Model::User->new );
$schema = $model->schema( 'user' );
