DAO library adapts the Data Access Object pattern to your application.
Installation
Set \Vegas\Db\Dao\Manager class as a service by adding following snippet into your services directory:
use Phalcon\DiInterface;
use Vegas\DI\ServiceProviderInterface;
/**
* Class DaoServiceProvider
*/
class DaoServiceProvider implements ServiceProviderInterface
{
const SERVICE_NAME = 'dao';
/**
* {@inheritdoc}
*/
public function register(DiInterface $di)
{
$di->set(self::SERVICE_NAME, function() use ($di) {
$dao = new \Vegas\Db\Dao\Manager;
return $dao->setDI($di);
}, true);
}
public function getDependencies()
{
return [];
}
}Example usage:
Inside injection-aware class:
$modelName = '\Foo\Models\Bar';
$model = new $modelName;
$daoManager = $this->getDI()->get('dao');
/** @var \Foo\Models\Dao\Bar $dao */
$dao = $daoManager->get($modelName);
// or
$dao = $daoManager->get($model);
/** @var \Foo\Models\Bar $result */
$result = $dao->findById('example_id');
/** @var \Foo\Models\Bar[] $results */
$results = $dao->findAll();For the full list of available methods please examine \Vegas\Db\Dao\DefaultDao class.
By default, DAO classes for specific collections/models should be placed under additional Dao suffix and should have the same name.
e.x. for \Foo\Models\Bar collection a \Foo\Models\Dao\Bar class should be created.
Currently there are no additional requirements for the class implementation.
