Laravel Model Tracker

A lightweight Laravel package to track changes in your models. Automatically logs all changes, including old values, new values, and the user responsible for the changes.

Features

Automatically tracks changes in any Eloquent model.
Stores old and new values of updated fields.
Logs the user who made the change (if authenticated).
Provides easy integration with a simple trait.
Configurable to exclude fields from tracking.
Includes a migration to store logs in a model_changes table.

Requirements

Laravel 8.x or 9.x
PHP 7.4 or higher

Installation

Install via Composer:

composer require temistocle1998/laravel-model-tracker

Publish configuration and migration files:

php artisan vendor:publish --tag=tracker-config
php artisan migrate

Add the TracksChanges trait to your model:

In any model where you want to track changes, simply include the TracksChanges trait:
```
use Tracker\Traits\TracksChanges;

class Product extends Model
{
    use TracksChanges;
}
```

Configuration

The package comes with a config file that can be customized to suit your needs. The configuration file can be found at config/tracker.php.

Example Config:

return [
    'enabled' => true, // Enable or disable the tracking
    'exclude_fields' => ['password', 'remember_token'], // Fields you don't want to track
];

Usage

Once the package is set up, any changes made to the models using the TracksChanges trait will automatically be logged. The logs are stored in the model_changes table.

Example of Change Logs

When a model is updated, the following log is created in the model_changes table:

model_type	model_id	user_id	changes	created_at
App\Models\Product	1	2	{"name": {"old_value": "Old Name", "new_value": "New Name"}}	2023-01-01 12:00:00

Retrieving Model Changes

You can fetch model changes using the ModelChange model.

use Tracker\Models\ModelChange;

// Get all changes for a specific model
$changes = ModelChange::where('model_type', 'App\Models\Product')
                      ->where('model_id', $productId)
                      ->get();

// Display the changes
foreach ($changes as $change) {
    echo $change->changes;
}

Displaying Changes in Your View

You can also display the changes in your views:

@foreach ($product->changes as $change)
    <p>Field: {{ $change['field'] }} | Old Value: {{ $change['old_value'] }} | New Value: {{ $change['new_value'] }}</p>
@endforeach
