README
Windwalker Model provides an abstract interface to build your own model logic.
Installation via Composer
Add this to the require block in your composer.json
.
{ "require": { "windwalker/model": "~2.0" } }
Create Model
Extends the AbstractModel to create your own model.
use Windwalker\Model\AbstractModel class MyModel extends AbstractModel { public function getItem() { return new stdClass; } } $model = new MyModel; $item = $model->getItem();
Database Model
Implements the DatabaseModelInterface
, we will able to get and set a DB object to access database.
Windwalker Model do not dependency to any Database package, you can integrate your favorite data source to get data.
use Windwalker\Model\AbstractModel use Windwalker\Model\DatabaseModelInterface; class MyModel extends AbstractModel implements DatabaseModelInterface { protected $db; public function __construct($db, Registry $state = null) { $this->db = $db; parent::__construct($state); } public function getDb() { return $this->db; } public function setDb($db) { $this->db = $db; } public function getList() { $this->db->setQuery('select * from users'); return $this->db->loadAll(); } }
Model State
Model maintains their own state that we can change this state to get different data.
class MyModel extends AbstractModel implements DatabaseModelInterface { // ... public function getUsers() { $published = $this->state->get('where.published', 1); $ordering = $this->state->get('list.ordering', 'id'); $direction = $this->state->get('list.direction', 'ASC'); $sql = "SELECT * FROM users " . " WHERE published = " . $published . " ORDER BY " . $ordering . " " . $direction; try { return $this->db->setQuery($sql)->loadAll(); } catch (\Exception $e) { $this->state->set('error', $e->getMessage()); return false; } } } $model = new MyModel; $state = $model->getState(); // Let's change model state $state->set('where.published', 1); $state->set('list.ordering', 'birth'); $state->set('list.direction', 'DESC'); $users = $model->getUsers(); if (!$users) { $error = $state->get('error'); }
Simple Way to Access State
Using get()
and set()
// Same as getState()->get(); $model->get('where.author', 5); // Same as getState()->set(); $model->set('list.ordering', 'RAND()');
State ArrayAccess
// Same as getState()->get(); $data = $model['list.ordering']; // Same as getState()->set(); $model['list.ordering'] = 'created_time';
