ray-di / Ray.CakeDbModule

A CakePHP database module for Ray.DI

Ray.CakeDbModule

This is the CakePHP Database Module for Ray.Di

Installation

Composer install

$ composer require ray/cake-database-module

Module install

You can Inject the database Connection instance to any class this way:

use Ray\Di\AbstractModule;
use Ray\CakeDbModule\CakeDbModule;

class AppModule extends AbstractModule
{
    protected function configure()
    {
        $this->install(new CakeDbModule('sqlite:///'));

        // or
        $this->install(new CakeDbModule('mysql://root@localhost/cake_db'));
    }
}

That will create inject instances of Cake\Database\Connection with the SQLite driver using the memory database or connect to the localhost mysql using the root credentials.

You can also be more specific and pass a configuraiton array as Cake\Database\Connection would accept it:

use Ray\Di\AbstractModule;
use Ray\CakeDbModule\CakeDbModule;

class AppModule extends AbstractModule
{
    protected function configure()
    {
        $config = [
            'className' => 'Cake\Database\Connection',
            'driver' => 'Cake\Database\Driver\Mysql',
            'username' => 'root',
            'password' => 'root',
            'database' => 'cake'
        ];
        $this->install(new CakeDbModule($config));
    }
}

Finally you can rely on already configured connections in cake's ConnectionManager and inject connections by name:

ConnectionManager::config('default', $config);

use Ray\Di\AbstractModule;
use Ray\CakeDbModule\CakeDbModule;

class AppModule extends AbstractModule
{
    protected function configure()
    {
        $this->install(new CakeDbModule('default'));
    }
}

DI trait

You can inject the connection instance on any class by using the Ray\CakeDbModule\DatabaseInject trait:

use Ray\CakeDbModule\DatabaseInject;

class MyThing
{
    use DatabaseInject;
}

This will make the methods getDbConnection() and setDbConnection() available in your class and will automatically inject the Connection instance when MyThing is instantiated using the Injector.

Wrapping methods inside a transaction

You can make any method run inside a transaction by using the @Transactional annotation. This is handy for saving operations:

use DateTime;
use Ray\CakeDbModule\Annotation\Trasactional;
use Ray\CakeDbModule\DatabaseInject;

class MyThing
{
    use DatabaseInject;

    /**
     * This will run inside a new transaction
     *
     * @Transactional
     */
    public function storeSomething()
    {
        $this->db->insert(
            'posts',
            ['name' => 'First', 'show_on' => new DateTime('+3 days')],
            ['created' => 'datetime']
        );
    }
}
