How do you create and use Phalcon’s custom model managers?

To create and use custom model managers in Phalcon, you can extend or customize the behavior of Phalcon\Mvc\Model\Manager. The model manager handles model interactions with the database, including events, relations, and metadata.

Here are the steps to create and use a custom model manager:

Step 1: Create a Custom Model Manager

You can extend the built-in Phalcon\Mvc\Model\Manager to create your own custom logic.

Example

<?php
use Phalcon\Mvc\Model\Manager as PhalconModelManager;

class CustomModelManager extends PhalconModelManager
{
    // Example: Add a custom method to handle some custom logic
    public function findActiveRecords($model, $conditions = [])
    {
        // Fetch only active records based on a condition
        return $this->createQuery('SELECT * FROM ' . $model . ' WHERE active = 1')->execute($conditions);
    }
}
?>

Step 2: Register Custom Model Manager in Dependency Injection

To use your custom model manager, you need to register it in the DI (Dependency Injection) container.

Example

<?php
use Phalcon\Di\FactoryDefault;

$di = new FactoryDefault();

$di->setShared('modelsManager', function () {
    return new CustomModelManager();
});
?>

Step 3: Use Custom Model Manager in Your Models

Once the custom model manager is registered, it will be automatically used by your models. You can access it via the modelsManager service.

Example

<?php
use Phalcon\Mvc\Model;

class Users extends Model
{
    public function getActiveUsers()
    {
        // Use the custom method from the custom model manager
        return $this->getModelsManager()->findActiveRecords(Users::class);
    }
}
?>

Step 4: Use the Custom Manager in Your Application

You can now use the custom model manager in your models or controllers to extend model functionality.

Example

<?php
// Get all active users using the custom method
$activeUsers = Users::getActiveUsers();
?>
