Attribute Modifiers

Version 8.0.0 brings the AttributeModifier contract, improving the way Auditable attributes can be modified, when creating an Audit.

Attribute Redactors

Attribute Redactors (previously called Audit Redactors) were introduced in version 6.1.0, making it easy to mask sensitive information when auditing.

Two redactors are included, out of the box.

LeftRedactor

The LeftRedactor will mask part of the data, from the left.

RightRedactor

The RightRedactor will work in the same fashion as the previous one, but like the name implies, it will mask the data from the right.

{tip} Depending on the length, both redactors should mask ~90% of the data.

Custom redactors

If the two default redactors don't suit your needs, you're free to implement your own.

A redactor is a class that implements the \OwenIt\Auditing\Contracts\AttributeRedactor interface.

{tip} The included redactors are a good starting point to get ideas for a new custom attribute redactor implementation.

Usage

<?php
namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use OwenIt\Auditing\Contracts\Auditable;
use OwenIt\Auditing\Redactors\LeftRedactor;

class Article extends Model implements Auditable
{
    use \OwenIt\Auditing\Auditable;

    /**
     * Attribute modifiers.
     *
     * @var array
     */
    protected $attributeModifiers = [
        'title' => LeftRedactor::class,
    ];

    // ...
}

{note} Auditable Transition won't work if an AttributeRedactor is set, since redacted data can't be used when transitioning states.

Attribute Encoders

The AttributeEncoder interface was introduced in version 8.0.0. By default, one encoder is included.

Base64Encoder

As the name implies, the Base64Encoder will encode attributes in Base64.

{tip} This comes in handy when dealing with binary data, that would otherwise break the underlying Eloquent model, when casting to JSON.

Custom encoders

In the same fashion as a custom AttributeRedactor, feel free to create your own AttributeEncoder implementations.

Just create a class implementing the \OwenIt\Auditing\Contracts\AttributeEncoder interface.

{tip} Use the included encoder as a starting point for your implementation.

Usage

<?php
namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use OwenIt\Auditing\Contracts\Auditable;
use OwenIt\Auditing\Redactors\LeftRedactor;

class Article extends Model implements Auditable
{
    use \OwenIt\Auditing\Auditable;

    /**
     * Attribute modifiers.
     *
     * @var array
     */
    protected $attributeModifiers = [
        'title' => Base64Encoder::class,
    ];

    // ...
}

{tip} When using the getModified() method to retrieve data from an Audit, any encoded attributes will be returned in their decoded form.
