Laravel Immutable Attributes

Make attributes on your Laravel models immutable...i.e. after the model is created, the value of the immutable attributes cannot change when updating records with Eloquent.

Installation

Requirements: This package requires PHP 7.1.3 or higher and Laravel 5.7

$ composer require zablockibros/laravel-immutable

The package will automatically register its service provider.

Define Immutable Attributes

Define the attributes to be immutable on your model:

<?php
 
namespace App\Models;
 
use Illuminate\Database\Eloquent\Model;
use ZablockiBros\Immutable\Traits\HasImmutableAttributes;
 
class YourModel extends Model
{
    use HasImmutableAttributes;
    
    /**
     * @var array
     */
    protected $immutable = [
        'name',
        'sku',
    ];

In this example, name and sku can be set on model creation, however, the attributes will not persist changes of their value to a database on update.

$model = new YourModel;
 
// set the attribute 
$model->name = 'test';
$model->name; // 'test'
 
// change it (pre-saving)
$model->name = 'changed';
$model->name; // 'changed'
 
// now we save the model
$model->save();
 
// can't change its value now
$model->name = 'nope';
$model->name; // 'changed'
 
// can't update it either
$model->save([
    'name' => 'nope',
]);
$model->name; // 'changed'
