Blameable behavior extension for Doctrine 2

Blameable behavior will automate the update of username or user reference fields on your Entities or Documents. It works through annotations and can update fields on creation, update, property subset update, or even on specific property value change.

This is very similar to Timestampable but sets a string or user object for a user association.

If you map the blame onto a string field, this extension will try to assign the user name. If you map the blame onto a association field, this extension will try to assign the user object to it.

Note that you need to set the user on the BlameableListener (unless you use the Symfony2 extension which does automatically assign the current security context user).

Features:

Automatic predefined user field update on creation, update, property subset update, and even on record property changes
ORM and ODM support using same listener
Specific annotations for properties, and no interface required
Can react to specific property or relation changes to specific value
Can be nested with other behaviors
Annotation, Yaml and Xml mapping support for extensions

Symfony:

Blameable is available as Bundle for Symfony2, together with all other extensions

This article will cover the basic installation and functionality of Blameable behavior

Setup and autoloading

Read the documentation or check the example code on how to setup and use the extensions in most optimized way.

Blameable Entity example:

Blameable annotations:

@Gedmo\Mapping\Annotation\Blameable this annotation tells that this column is blameable by default it updates this column on update. If column is not a string field or an association it will trigger an exception.

Available configuration options:

on - is main option and can be create, update, change this tells when it should be updated
field - only valid if on="change" is specified, tracks property or a list of properties for changes
value - only valid if on="change" is specified and the tracked field is a single field (not an array), if the tracked field has this value then it updates the blame

Note: that Blameable interface is not necessary, except in cases there you need to identify entity as being Blameable. The metadata is loaded only once then cache is activated

Column is a string field:

<?php
namespace Entity;

use Gedmo\Mapping\Annotation as Gedmo;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 */
class Article
{
    /** @ORM\Id @ORM\GeneratedValue @ORM\Column(type="integer") */
    private $id;

    /**
     * @ORM\Column(type="string", length=128)
     */
    private $title;

    /**
     * @ORM\Column(name="body", type="string")
     */
    private $body;

    /**
     * @var string $createdBy
     *
     * @Gedmo\Blameable(on="create")
     * @ORM\Column(type="string")
     */
    private $createdBy;

    /**
     * @var string $updatedBy
     *
     * @Gedmo\Blameable(on="update")
     * @ORM\Column(type="string")
     */
    private $updatedBy;

    /**
     * @var datetime $contentChangedBy
     *
     * @ORM\Column(name="content_changed_by", type="string", nullable=true)
     * @Gedmo\Timestampable(on="change", field={"title", "body"})
     */
    private $contentChangedBy;

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

    public function setTitle($title)
    {
        $this->title = $title;
    }

    public function getTitle()
    {
        return $this->title;
    }

    public function setBody($body)
    {
        $this->body = $body;
    }

    public function getBody()
    {
        return $this->body;
    }

    public function getCreatedBy()
    {
        return $this->createdBy;
    }

    public function getUpdatedBy()
    {
        return $this->updatedBy;
    }

    public function getContentChangedBy()
    {
        return $this->contentChangedBy;
    }
}

Column is an association:

<?php
namespace Entity;

use Gedmo\Mapping\Annotation as Gedmo;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 */
class Article
{
    /** @ORM\Id @ORM\GeneratedValue @ORM\Column(type="integer") */
    private $id;

    /**
     * @ORM\Column(type="string", length=128)
     */
    private $title;

    /**
     * @ODM\String
     */
    private $body;

    /**
     * @var User $createdBy
     *
     * @Gedmo\Blameable(on="create")
     * @ORM\ManyToOne(targetEntity="Path\To\Entity\User")
     * @ORM\JoinColumn(name="created_by", referencedColumnName="id")
     */
    private $createdBy;

    /**
     * @var User $updatedBy
     *
     * @Gedmo\Blameable(on="update")
     * @ORM\ManyToOne(targetEntity="Path\To\Entity\User")
     * @ORM\JoinColumn(name="updated_by", referencedColumnName="id")
     */
    private $updatedBy;

    /**
     * @var User $contentChangedBy
     *
     * @Gedmo\Timestampable(on="change", fields={"title", "body"})
     * @ORM\ManyToOne(targetEntity="Path\To\Entity\User")
     * @ORM\JoinColumn(name="content_changed_by", referencedColumnName="id")
     */
    private $contentChangedBy;

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

    public function setTitle($title)
    {
        $this->title = $title;
    }

    public function getTitle()
    {
        return $this->title;
    }

    public function setBody($body)
    {
        $this->body = $body;
    }

    public function getBody()
    {
        return $this->body;
    }

    public function getCreatedBy()
    {
        return $this->createdBy;
    }

    public function getUpdatedBy()
    {
        return $this->updatedBy;
    }

    public function getContentChangedBy()
    {
        return $this->contentChangedBy;
    }
}

Blameable Document example:

<?php
namespace Document;

use Gedmo\Mapping\Annotation as Gedmo;
use Doctrine\ODM\MongoDB\Mapping\Annotations as ODM;

/**
 * @ODM\Document(collection="articles")
 */
class Article
{
    /** @ODM\Id */
    private $id;

    /**
     * @ODM\String
     */
    private $title;

    /**
     * @var string $createdBy
     *
     * @ODM\String
     * @Gedmo\Blameable(on="create")
     */
    private $createdBy;

    /**
     * @var string $updatedBy
     *
     * @ODM\String
     * @Gedmo\Blameable
     */
    private $updatedBy;

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

    public function setTitle($title)
    {
        $this->title = $title;
    }

    public function getTitle()
    {
        return $this->title;
    }

    public function getCreatedBy()
    {
        return $this->createdBy;
    }

    public function getUpdatedBy()
    {
        return $this->updatedBy;
    }
}

Now on update and creation these annotated fields will be automatically updated

Yaml mapping example:

Yaml mapped Article: /mapping/yaml/Entity.Article.dcm.yml

---
Entity\Article:
  type: entity
  table: articles
  id:
    id:
      type: integer
      generator:
        strategy: AUTO
  fields:
    title:
      type: string
      length: 64
    createdBy:
      type: string
      gedmo:
        blameable:
          on: create
    updatedBy:
      type: string
      gedmo:
        blameable:
          on: update

Xml mapping example

<?xml version="1.0" encoding="UTF-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
                  xmlns:gedmo="http://gediminasm.org/schemas/orm/doctrine-extensions-mapping">

    <entity name="Mapping\Fixture\Xml\Blameable" table="blameables">
        <id name="id" type="integer" column="id">
            <generator strategy="AUTO"/>
        </id>

        <field name="createdBy" type="string">
            <gedmo:blameable on="create"/>
        </field>
        <field name="updatedBy" type="string">
            <gedmo:blameable on="update"/>
        </field>
        <field name="publishedBy" type="string" nullable="true">
            <gedmo:blameable on="change" field="status.title" value="Published"/>
        </field>

        <many-to-one field="status" target-entity="Status">
            <join-column name="status_id" referenced-column-name="id"/>
        </many-to-one>
    </entity>

</doctrine-mapping>

Advanced examples:

Using dependency of property changes

Add another entity which would represent Article Type:

<?php
namespace Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 */
class Type
{
    /** @ORM\Id @ORM\GeneratedValue @ORM\Column(type="integer") */
    private $id;

    /**
     * @ORM\Column(type="string", length=128)
     */
    private $title;

    /**
     * @ORM\OneToMany(targetEntity="Article", mappedBy="type")
     */
    private $articles;

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

    public function setTitle($title)
    {
        $this->title = $title;
    }

    public function getTitle()
    {
        return $this->title;
    }
}

Now update the Article Entity to reflect publishedBy on Type change:

<?php
namespace Entity;

use Gedmo\Mapping\Annotation as Gedmo;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 */
class Article
{
    /** @ORM\Id @ORM\GeneratedValue @ORM\Column(type="integer") */
    private $id;

    /**
     * @ORM\Column(type="string", length=128)
     */
    private $title;

    /**
     * @var string $createdBy
     *
     * @Gedmo\Blameable(on="create")
     * @ORM\Column(type="string")
     */
    private $createdBy;

    /**
     * @var string $updatedBy
     *
     * @Gedmo\Blameable(on="update")
     * @ORM\Column(type="string")
     */
    private $updatedBy;

    /**
     * @ORM\ManyToOne(targetEntity="Type", inversedBy="articles")
     */
    private $type;

    /**
     * @var string $publishedBy
     *
     * @ORM\Column(type="string", nullable=true)
     * @Gedmo\Blameable(on="change", field="type.title", value="Published")
     */
    private $publishedBy;

    public function setType($type)
    {
        $this->type = $type;
    }

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

    public function setTitle($title)
    {
        $this->title = $title;
    }

    public function getTitle()
    {
        return $this->title;
    }

    public function getCreatedBy()
    {
        return $this->createdBy;
    }

    public function getUpdatedBy()
    {
        return $this->updatedBy;
    }

    public function getPublishedBy()
    {
        return $this->publishedBy;
    }
}

Yaml mapped Article: /mapping/yaml/Entity.Article.dcm.yml

---
Entity\Article:
  type: entity
  table: articles
  id:
    id:
      type: integer
      generator:
        strategy: AUTO
  fields:
    title:
      type: string
      length: 64
    createdBy:
      type: string
      gedmo:
        blameable:
          on: create
    updatedBy:
      type: string
      gedmo:
        blameable:
          on: update
    publishedBy:
      type: string
      gedmo:
        blameable:
          on: change
          field: type.title
          value: Published
  manyToOne:
    type:
      targetEntity: Entity\Type
      inversedBy: articles

Now few operations to get it all done:

<?php
$article = new Article;
$article->setTitle('My Article');

$em->persist($article);
$em->flush();
// article: $createdBy, $updatedBy were set

$type = new Type;
$type->setTitle('Published');

$article = $em->getRepository('Entity\Article')->findByTitle('My Article');
$article->setType($type);

$em->persist($article);
$em->persist($type);
$em->flush();
// article: $publishedBy, $updatedBy were set

$article->getPublishedBy(); // the user that published this article

Easy like that, any suggestions on improvements are very welcome

Traits

You can use blameable traits for quick createdBy updatedBy string definitions when using annotation mapping.

Note: this feature is only available since php 5.4.0. And you are not required to use the Traits provided by extensions.

<?php
namespace Blameable\Fixture;

use Gedmo\Blameable\Traits\BlameableEntity;
use Gedmo\Mapping\Annotation as Gedmo;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 */
class UsingTrait
{
    /**
     * Hook blameable behavior
     * updates createdBy, updatedBy fields
     */
    use BlameableEntity;

    /**
     * @ORM\Id
     * @ORM\GeneratedValue
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\Column(length=128)
     */
    private $title;
}

Note: you must import Gedmo\Mapping\Annotation as Gedmo and Doctrine\ORM\Mapping as ORM annotations. If you use mongodb ODM import Doctrine\ODM\MongoDB\Mapping\Annotations as ODM and BlameableDocument instead.

Traits are very simple and if you use different field names I recomment to simply create your own ones based per project. These ones are standing as an example.
