Installation

Step 1: Download bundle

If your project already uses Symfony Flex, execute this command to download, register and configure the bundle automatically:, _(*1)

composer require indragunawan/sequence-bundle

If you install without using Symfony Flex, first add the bundle by using composer then enable the bundle by adding new Indragunawan\SequenceBundle\IndragunawanSequenceBundle() to the list of registered bundles in the app/AppKernel.php file of your project, _(*2)

Step 2: Create your Sequence class

<?php
// src/App/Entity/Sequence.php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use Indragunawan\SequenceBundle\Model\Sequence as BaseSequence;

/**
* @ORM\Entity(repositoryClass="App\Repository\SequenceRepository")
*/
class Sequence extends BaseSequence
{
    /**
    * @ORM\Id()
    * @ORM\GeneratedValue(strategy="IDENTITY")
    * @ORM\Column(type="integer")
    */
    private $id;

    public function getId()
    {
        return $this->id;
    }
}

Step 3: Configure the bundle

# app/config/config.yml
indragunawan_sequence:
orm:
    class: App\Entity\Sequence
    manager_name: default #if not set then the default value is 'default'

Step 4: Update your database schema

$ php bin/console doctrine:schema:update --force

Usage

Insert your sequence manually to sequence table in database

Format

For format you can see table below:

Reserved Placeholder

• NUMBER (an integer contains sequence counter).
• php date format See this.
• Rj, Rn, Ry, RY, Rg for Roman numeral of date format.

Example

another example can be see in Tests/Utils/PlaceholderReplacerTest.php, _(*3)

SequenceManager

NOTE: Sequence manager can only be use inside doctrine transaction

Call in Controller

// use Indragunawan\SequenceBundle\Services\SequenceManager
$sequenceManager = $this->get(SequenceManager::class);
$em->transactional(function () use ($entity) {
  $entity->setSeqNum($sequenceManager->getNextValue('sequence_name'));
});

Call in Event Listener

// use Indragunawan\SequenceBundle\Services\SequenceManagerInterface
// Inject SequenceManagerInterface on constructor

public function prePersist(LifecycleEventArgs $args)
{
    $entity = $args->getObject();
    if ($entity instanceof EntityClass) {
        $args->getObjectManager()->transactional(function () use ($entity) {
            $entity->setSeqNum($this->sequenceManager->getNextValue('sequence_name'));
        });
    }
}

ResetCounter

$ php bin/console indragunawan:sequence:reset-counter sequence_name

You can put this command into Crontab for periodically restart the counter., _(*4)
