How do you use Phalcon’s PhalconMvcModelTransactionManager class?

How do you use Phalcon’s PhalconMvcModelTransactionManager class?

To use Phalcon’s Phalcon\Mvc\Model\TransactionManager class, follow these steps:

Step 1: Initialize the Transaction Manager

  • In your DI container (e.g., app/config/services.php), set up the Transaction Manager:

Example

<?php
use Phalcon\Mvc\Model\Transaction\Manager as TransactionManager;

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

Step 2: Start a Transaction

  • In your model or controller, start a transaction using the manager:

Example

<?php
use Phalcon\Mvc\Model\Transaction\Manager;

$transactionManager = new TransactionManager();
$transaction = $transactionManager->get();
?>

Step 3: Use the Transaction in Models

  • Use the transaction while saving models:

Example

<?php
$user = new User();
$user->setTransaction($transaction); // Set the transaction

$user->name = 'John Doe';
$user->email = 'john@example.com';

if ($user->save() === false) {
    $transaction->rollback('Failed to save user');
}
?>

Step 4: Commit or Rollback

  • Commit the transaction if all operations succeed:

Example

<?php
$transaction->commit();
?>

  • If an error occurs, you can roll back the transaction, which was already shown in Step 3.

Step 5: Handle Exceptions

  • Wrap the transaction in a try-catch block to manage exceptions effectively:

Example

<?php
try {
    $transaction = $transactionManager->get();
    // Model operations...
    $transaction->commit();
} catch (\Exception $e) {
    $transaction->rollback($e->getMessage());
}
?>
