Blameable Behavior Extension for Doctrine

The Blameable behavior automates the update of user information on your Doctrine objects.

Index

Getting Started

The blameable behavior can be added to a supported Doctrine object manager by registering its event subscriber when creating the manager.

use Gedmo\Blameable\BlameableListener;

$listener = new BlameableListener();

// The $om is either an instance of the ORM's entity manager or the MongoDB ODM's document manager
$om->getEventManager()->addEventSubscriber($listener);

Then, once your application has it available (i.e. after validating the authentication for your user during an HTTP request), you can set a reference to the user to be blamed for changes by calling the listener's setUserValue method.

// The $user can be either an object or a string
$listener->setUserValue($user);

Configuring Blameable Objects

The blameable extension can be configured with annotations, attributes, or XML configuration (matching the mapping of your domain models). The full configuration for annotations and attributes can be reviewed in the linked documentation.

The below examples show the simplest and default configuration for the extension, setting a field when the model is updated.

Attribute Configuration

<?php
namespace App\Entity;

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

#[ORM\Entity]
class Article
{
    #[ORM\Id]
    #[ORM\GeneratedValue]
    #[ORM\Column(type: Types::INTEGER)]
    public ?int $id = null;

    #[ORM\Column(type: Types::STRING)]
    #[Gedmo\Blameable]
    public ?string $updatedBy = null;
}

XML Configuration

<?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="App\Model\Article" table="articles">
        <id name="id" type="integer" column="id">
            <generator strategy="AUTO"/>
        </id>

        <field name="updatedBy" type="string">
            <gedmo:blameable on="update"/>
        </field>
    </entity>
</doctrine-mapping>

Annotation Configuration

Note

Support for annotations is deprecated and will be removed in 4.0.

<?php
namespace App\Entity;

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

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

    /**
     * @ORM\Column(type="string")
     * @Gedmo\Blameable
     */
    public ?string $updatedBy = null;
}

Supported Field Types

The blameable extension supports the following field types for a blameable field:

  • String (string, or when using the ORM and DBAL, ascii_string)
  • Integer (int only)
  • UUID or ULID (requires a third party package providing a uuid or ulid Doctrine type; popular packages for the ORM and DBAL include ramsey/uuid-doctrine and symfony/doctrine-bridge)
  • A many-to-one association (ORM) or reference many reference (MongoDB ODM)

Using Traits

The blameable extension provides traits which can be used to quickly add fields, and optionally the mapping configuration, for a created by and updated by username to be updated for the create and update blameable actions. These traits are provided as a convenience for a common configuration, for other use cases it is suggested you add your own fields and configurations.

  • Gedmo\Blameable\Traits\Blameable adds a $createdBy and $updatedBy property, with getters and setters
  • Gedmo\Blameable\Traits\BlameableDocument adds a $createdBy and $updatedBy property, with getters and setters and mapping annotations and attributes for the MongoDB ODM
  • Gedmo\Blameable\Traits\BlameableEntity adds a $createdBy and $updatedBy property, with getters and setters and mapping annotations and attributes for the ORM

Logging Changes For Specific Actions

In addition to supporting logging the user for general create and update actions, the extension can also be configured to log the user who made a change for specific fields or values.

Single Field Changed To Specific Value

For example, we want to record the user who published an article on a news site. To do this, we add a field to our object and configure it using the change action, specifying the field and value we want it to match.

<?php
namespace App\Entity;

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

#[ORM\Entity]
class Article
{
    #[ORM\Id]
    #[ORM\GeneratedValue]
    #[ORM\Column(type: Types::INTEGER)]
    public ?int $id = null;

    #[ORM\Column(type: Types::BOOLEAN)]
    public bool $published = false;

    /**
     * Field to track the user who last made any change to this article. 
     */
    #[ORM\Column(type: Types::STRING)]
    #[Gedmo\Blameable]
    public ?string $updatedBy = null;

    /**
     * Field to track the user who published this article. 
     */
    #[ORM\Column(type: Types::STRING, nullable: true)]
    #[Gedmo\Blameable(on: 'change', field: 'published', value: true)]
    public ?string $publishedBy = null;
}

The change action can also be configured to watch for changes on related objects using a dot notation path. In this example, we log the user who updated the article and placed it into an archived category.

<?php
namespace App\Entity;

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

#[ORM\Entity]
class Article
{
    #[ORM\Id]
    #[ORM\GeneratedValue]
    #[ORM\Column(type: Types::INTEGER)]
    public ?int $id = null;

    #[ORM\ManyToOne(targetEntity: Category::class)]
    public ?Category $category = null;

    /**
     * Field to track the user who last made any change to this article. 
     */
    #[ORM\Column(type: Types::STRING)]
    #[Gedmo\Blameable]
    public ?string $updatedBy = null;

    /**
     * Field to track the user who archived this article. 
     */
    #[ORM\Column(type: Types::STRING, nullable: true)]
    #[Gedmo\Blameable(on: 'change', field: 'category.archived', value: true)]
    public ?string $archivedBy = null;
}

One of Many Fields Changed

The extension can also update a blameable field when using the change action by specifying a list of fields to watch. This also supports the dotted path notation, allowing you to watch changes on the model itself as well as related data.

<?php
namespace App\Entity;

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

#[ORM\Entity]
class Article
{
    #[ORM\Id]
    #[ORM\GeneratedValue]
    #[ORM\Column(type: Types::INTEGER)]
    public ?int $id = null;

    #[ORM\ManyToOne(targetEntity: Category::class)]
    public ?Category $category = null;

    #[ORM\Column(type: Types::STRING, nullable: true)]
    public ?string $metaDescription = null;

    #[ORM\Column(type: Types::STRING, nullable: true)]
    public ?string $metaKeywords = null;

    /**
     * Field to track the user who last made any change to this article. 
     */
    #[ORM\Column(type: Types::STRING)]
    #[Gedmo\Blameable]
    public ?string $updatedBy = null;

    /**
     * Field to track the user who last modified this article's SEO metadata. 
     */
    #[ORM\Column(type: Types::STRING, nullable: true)]
    #[Gedmo\Blameable(on: 'change', field: ['metaDescription', 'metaKeywords', 'category.metaDescription', 'category.metaKeywords'])]
    public ?string $seoMetadataChangedBy = null;
}
