sfPropelVersionableBehaviorPlugin plugin

The sfPropelVersionableBehaviorPlugin is a symfony plugin that provides versioning capabilities to any Propel object.


  • Fully unit tested
  • Revert objects to previous versions easily
  • Conditional versioning


  • Install the plugin

    symfony plugin-install http://plugins.symfony-project.com/sfPropelVersionableBehaviorPlugin

  • Enable Propel behavior support in propel.ini:

    propel.builder.AddBehaviors = true

  • Add necessary fields to your each of your model tables that you want to make versionable:

    [xml] or uuid: { type: char, size: 36, required: true } version: { type: integer, size: 11, required: true }

  • Rebuild your database and model (the plugin uses two tables to store object version history)


    php symfony propel-build-all

  • Enable the behavior for the Propel models that you want to extend. For instance, to extend an Article Propel class:


    $columns_map = array('uuid' => ArticlePeer::UUID, 'version' => ArticlePeer::VERSION);

    sfPropelBehavior::add('Article', array('versionable' => array('columns' => $columns_map)));

    Column map values mean:

    • uuid : Model column holding resource's universally unique identifier (behavior takes care of generating these)
    • version : Model column holding resource's current version number


Reverting to a previous version

$article = new Article();
$article->setTitle('First version of article');
$article->save(); // $article->getVersion() == 1
$article->setTitle('Second version of article');
$article->save(); // $article->getVersion() == 2
$article->toVersion(1); // $article->getTitle() == 'First version of article'
$article->save(); // $article->getVersion() == 3

Retrieving a resource version history

foreach ($article->getAllVersions() as $version)
   $history_article = $version->getResourceInstance();
   echo sprintf("Version %d title : %s\n", 
 * Outputs:
 * Version 1 title: First version of article
 * Version 2 title: Second version of article
 * Version 3 title: First version of article

Conditional versioning

You may not want to have a new version of resource created each time it is saved.

Just add a versionConditionMet() method to your stub class. It is called each time object's save(). No version is created if it returns false.

Example :

// lib/model/Article.php
public function versionConditionMet()
  return $this->getTitle() != 'do not version me';
$article = new Article();
$article->setTitle('New article');
$article->save(); // article is saved and a new version is created
$article->setTitle('do not version me');
$article->save(); // article is saved, no new version is created

It is possible to specify a different versionConditionMet() method name by defining it when registring behavior :

sfPropelBehavior::add('Article', array('versionable' => array('columns' => $columns_map, 'conditional' => 'myMethod')));

It is possible to change this method at runtime :

$previous_method = sfPropelVersionableBehavior::setVersionConditionMethod('myMethod');

Public API

Object API

Enabling the behaviors adds / modifies the following method to the Propel objects :

  • void save(): Adds a new version to resource's version history
  • void delete(): Deletes resource's version history
  • void toVersion(integer $version_number): Populates resource properties with values from the requested version
  • ResourceVersion getLastVersion(): Returns resource's last version
  • array getAllVersions(): Returns all resource versions in an array

!ResourceVersion API

  • BaseObject getResourceInstance(): Returns resource instance populated with attributes from the version
  • int getNumber(): Returns the version number of the version object

sfPropelVersionableBehavior API

  • (static) string setVersionConditionMethod(string $method_name): Sets object method used to decide if a new version should be created
  • (static) string getVersionConditionMethod(): Returns version condition method name



  • Add unit tests to check version_attributes deletion
  • Make plugin compatible with sfPropel's i18n capabilities
  • Replace uuid by a simple composite key class name + id
