README

Automatic auditing for Eloquent relationship changes (attach, detach, sync) using Laravel Auditing.

Features

• 🔍 Automatic Tracking: Captures before/after state of relationship changes
• 📝 Detailed Logs: Stores complete related model data, not just IDs
• 🎯 Event-Based: Uses owen-it/laravel-auditing for consistent audit logs
• ⚡ Zero Configuration: Works out of the box after trait inclusion
• 🔧 Flexible: Supports BelongsToMany and MorphToMany relationships
• 📦 Lightweight: Minimal overhead, maximum value

Installation

composer require a2zwebltd/auditable-relations

Requirements

• PHP 8.2+
• Laravel 10, 11, 12, or 13
• owen-it/laravel-auditing 13/14

Quick Start

1. Implement Auditable on Your Model

use Illuminate\Database\Eloquent\Model;
use OwenIt\Auditing\Auditable as AuditableTrait;
use OwenIt\Auditing\Contracts\Auditable;

class Post extends Model implements Auditable
{
    use AuditableTrait;
}

2. Add the Trait and Wrap Your Relationships

use A2ZWeb\AuditableRelations\Traits\AuditsRelationships;
use Illuminate\Database\Eloquent\Relations\BelongsToMany;

class Post extends Model implements Auditable
{
    use AuditableTrait;
    use AuditsRelationships;

    public function tags(): BelongsToMany
    {
        return $this->auditableRelation(
            $this->belongsToMany(Tag::class)
        );
    }
}

That's it! Now all changes to the tags relationship will be automatically audited.

Usage Examples

Basic Usage

$post = Post::find(1);

// These operations are automatically audited
$post->tags()->attach([1, 2, 3]);
$post->tags()->detach([2]);
$post->tags()->sync([1, 3, 4]);

What Gets Logged

Each operation creates an audit log entry like:

[
    'event' => 'synced', // or 'attached', 'detached'
    'auditable_type' => 'App\Models\Post',
    'auditable_id' => 1,
    'old_values' => [
        'tags' => [
            ['id' => 1, 'name' => 'Laravel', 'created_at' => '...'],
            ['id' => 2, 'name' => 'PHP', 'created_at' => '...'],
        ]
    ],
    'new_values' => [
        'tags' => [
            ['id' => 1, 'name' => 'Laravel', 'created_at' => '...'],
            ['id' => 3, 'name' => 'Vue', 'created_at' => '...'],
            ['id' => 4, 'name' => 'Tailwind', 'created_at' => '...'],
        ]
    ],
    'user_id' => 123,
    'user_type' => 'App\Models\User',
]

Multiple Relationships

You can audit multiple relationships on the same model:

class Post extends Model implements Auditable
{
    use AuditableTrait;
    use AuditsRelationships;

    public function tags(): BelongsToMany
    {
        return $this->auditableRelation(
            $this->belongsToMany(Tag::class)
        );
    }

    public function categories(): BelongsToMany
    {
        return $this->auditableRelation(
            $this->belongsToMany(Category::class)
        );
    }

    public function attachments(): MorphToMany
    {
        return $this->auditableRelation(
            $this->morphToMany(File::class, 'attachable')
        );
    }
}

Polymorphic Relationships

Works seamlessly with polymorphic relationships:

class Post extends Model implements Auditable
{
    use AuditableTrait;
    use AuditsRelationships;

    public function images(): MorphToMany
    {
        return $this->auditableRelation(
            $this->morphToMany(Image::class, 'imageable')
        );
    }
}

Supported Relationships

• ✅ BelongsToMany
• ✅ MorphToMany
• ⏳ Other relationship types (planned)

Configuration

The package respects Laravel Auditing's global configuration:

// config/audit.php
return [
    'enabled' => true,        // Disable to stop all auditing
    'console' => false,       // Audit console commands
    // ... other audit config
];

Advanced Usage

Conditional Auditing

You can control auditing at runtime:

// Temporarily disable auditing
config(['audit.enabled' => false]);
$post->tags()->sync([1, 2, 3]); // Not audited
config(['audit.enabled' => true]);

Custom Event Names

The package uses standard event names:

• attached - When models are attached
• detached - When models are detached
• synced - When models are synced

Accessing Audit Logs

use OwenIt\Auditing\Models\Audit;

// Get all audits for a model
$audits = Audit::where('auditable_type', Post::class)
    ->where('auditable_id', 1)
    ->get();

// Get relationship change audits
$relationshipAudits = Audit::where('auditable_type', Post::class)
    ->whereIn('event', ['attached', 'detached', 'synced'])
    ->get();

How It Works

Architecture

1. Trait Application: AuditsRelationships trait wraps relationship definitions
2. Relationship Proxy: Creates auditable versions of BelongsToMany and MorphToMany
3. Operation Interception: Intercepts attach(), detach(), and sync() calls
4. State Capture: Records relationship state before and after the operation
5. Event Dispatch: Fires AuditCustom event with the captured data
6. Audit Creation: Laravel Auditing processes the event and creates the audit log

Performance

• Minimal overhead: Only one additional query per operation (to capture current state)
• Efficient: Uses existing Laravel Auditing infrastructure
• Asynchronous-ready: Compatible with queued audit processing

Comparison with Alternatives

Unlike other solutions:

• ✅ Complete Data: Stores full related model data, not just IDs
• ✅ Native Integration: Uses Laravel Auditing's standard audit model
• ✅ Zero Config: No additional tables or setup required
• ✅ Framework-Native: Uses Laravel's event system

Troubleshooting

Audits Not Appearing

1. Verify auditing is enabled:

config('audit.enabled'); // Should be true

1. Check model implements Auditable:

class Post extends Model implements \OwenIt\Auditing\Contracts\Auditable
{
    use \OwenIt\Auditing\Auditable;
}

1. Ensure relationship is wrapped:

public function tags(): BelongsToMany
{
    return $this->auditableRelation( // Don't forget this!
        $this->belongsToMany(Tag::class)
    );
}

Console Commands Not Audited

Enable console auditing in config/audit.php:

'console' => true,

Testing

composer test
