Installation

Step 1: Download the Bundle

Open a command console, go to your project directory and execute the following command to download the latest version of this bundle:

$ composer require enterprisephp/doctrine-lock-bundle "dev-master"

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.

Step 2: Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in the app/AppKernel.php file of your project:

<?php
// app/AppKernel.php

// ...
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            // ...

            new EP\DoctrineLockBundle\EPDoctrineLockBundle(),
        );

        // ...
    }

    // ...
}

Usage

Doctrine Object Lock

use EP\DoctrineLockBundle\Params\ObjectLockParams;
// ...
$objectLocker = $container->get('ep.doctrine.object.locker');
//lock fully
$objectLocker->lock(new DummyEntity());
//lock delete process
$objectLocker->lock(new DummyEntity(), ObjectLockParams::DELETE_LOCK);
//lock insert process
$objectLocker->lock(new DummyEntity(), ObjectLockParams::INSERT_LOCK);
//lock update process
$objectLocker->lock(new DummyEntity(), ObjectLockParams::UPDATE_LOCK);

Doctrine Object Unlock

use EP\DoctrineLockBundle\Params\ObjectLockParams;
// ...
$objectLocker = $container->get('ep.doctrine.object.locker');
//unlock full lock
$objectLocker->unlock(new DummyEntity());
//unlock delete process
$objectLocker->unlock(new DummyEntity(), ObjectLockParams::DELETE_LOCK);
//unlock insert process
$objectLocker->unlock(new DummyEntity(), ObjectLockParams::INSERT_LOCK);
//unlock update process
$objectLocker->unlock(new DummyEntity(), ObjectLockParams::UPDATE_LOCK);

Doctrine Object Switch Lock

use EP\DoctrineLockBundle\Params\ObjectLockParams;
// ...
$objectLocker = $container->get('ep.doctrine.object.locker');
//switch full lock
$objectLocker->switchLock(new DummyEntity());
//switch delete process
$objectLocker->switchLock(new DummyEntity(), ObjectLockParams::DELETE_LOCK);
//switch insert process
$objectLocker->switchLock(new DummyEntity(), ObjectLockParams::INSERT_LOCK);
//unswitchlock update process
$objectLocker->switchLock(new DummyEntity(), ObjectLockParams::UPDATE_LOCK);

Doctrine Object Is Locked

use EP\DoctrineLockBundle\Params\ObjectLockParams;
// ...
$objectLocker = $container->get('ep.doctrine.object.locker');
//is full locked
$objectLocker->isLocked(new DummyEntity());
//is delete locked
$objectLocker->isLocked(new DummyEntity(), ObjectLockParams::DELETE_LOCK);
//is insert locked
$objectLocker->isLocked(new DummyEntity(), ObjectLockParams::INSERT_LOCK);
//is update locked
$objectLocker->isLocked(new DummyEntity(), ObjectLockParams::UPDATE_LOCK);

Example Use

$objectLocker = $container->get('ep.doctrine.object.locker');
//lock object
$objectLocker->lock(new DummyEntity());
$em->persist(new DummyEntity()); // this will throw LockedObjectException

Doctrine Entity Lock

Add Lockable annotation and lockable trait

namespace AppBundle\Entity;

use EP\DoctrineLockBundle\Traits\LockableTrait;
use EP\DoctrineLockBundle\Annotations\Lockable;

/**
 * @Lockable
 */
class DummyEntity
{
    use LockableTrait;
    // ...

Example Use

//create new dummy entity
$dummyEntity = new DummyEntity();
$dummyEntity
    ->setTitle('Dummy Entity Title')
    ->setDescription('Dummy Entity Description')
    ->setUpdateLocked(true) //lock entity for update process
    ->setDeleteLocked(true) //lock entity for delete process
;
$em->persist($dummyEntity);
$em->flush();

$dummyEntity->setTitle('Update Dummy Entity Title');
$em->persist($dummyEntity);
$em->flush(); // this will throw LockedEntityException because entity have update lock

$em->remove($dummyEntity); // this will throw LockedEntityException because entity have delete lock
Unlock Entity Lock
//unlock update lock
$dummyEntity->setUpdateLocked(false);
//unlock delete lock
$dummyEntity->setDeleteLocked(false);
