Laravel Eraser

Laravel Eraser focuses on Erasing Eloquent Model Relation. It has two modes of operation.

• Manual: this mode require the developer to define erasable array contains relations should be deleted
• Auto: this mode use auto-discover for relations to be deleted

Supported Laravel versions

Laravel Version	Eraser Version
12.x	1.0+

Getting Started

Requires:

• PHP 8.2+
• Laravel 12.x+

1: First, use Composer to install laravel-eraser into your project:

composer require "hith/laravel-eraser"

2: Then, publish config file:

php artisan vendor:publish --tag=eraser-config

3: Finally, Use the package in two ways:

• By adding traits directly to your models.
• By using the Eraser class to delete/clean models.

Usage of traits:

-there are two types of traits [manual , auto]:

Manual Eraser Trait:

use Eraser\Traits\HasManualEraser;

class Post extends Model
{
    use HasManualEraser;

    public array $erasable = ['comments','tags'];

    public function user(): BelongsTo
    {
        return $this->belongsTo(User::class);
    }

    public function comments(): HasMany
    {
        return $this->hasMany(Comment::class);
    }

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

Then instead of:

$post->comments()->delete();
$post->tags()->detach();
$post->delete();

Simply do:

$post->delete();

Or, if you just want to clear relations without deleting the model:

$post->clean();

Auto Eraser Trait:

use Eraser\Traits\HasAutoEraser;

class Post extends Model
{
    use HasAutoEraser;

    public function user(): BelongsTo
    {
        return $this->belongsTo(User::class);
    }

    public function comments(): HasMany
    {
        return $this->hasMany(Comment::class);
    }

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

As with the manual trait, simply do:

$post->clean();
// or
$post->delete();

The user() relation will not be deleted in either mode, as it is considered a parent relation.

Usage of Eraser Class:

• Manual Mode (default):

use Eraser\Eraser;

$eraser = new Eraser();    // Manual is the default
$eraser->clean($model);    // cleans relations only
$eraser->delete($model);   // or cleans relations and deletes model

• Auto Mode

use Eraser\Eraser;

$eraser = new Eraser('auto');    // set eraser to auto
$eraser->clean($model);
$eraser->delete($model);

Usage of Eraser Facade:

use Eraser\Facades\Erase;

Erase::clean($model);   // Manual is the default
Erase::delete($model);  // or cleans relations and deletes model

// Erase Facade default mode is manual
// use `type()` method to set type
// types: [manual,auto]
Erase::type('auto')->clean($model);

Eraser Configuration

You can alter the behavior of the eraser either globally using the eraser config file or by defining some of this attributes on the model.

/**
* Determines whether the "eraser" should automatically start deleting
* related models when the parent model is being deleted.
* Default: true
* */
public bool $eraser_onDeleteStart = true;

/**
 * Controls whether relations to be deleted should be automatically
 * discovered when using the Auto Eraser functionality.
 * Default: true
 * */
public bool $eraser_autoDiscover = true;

/**
 * Enables or disables logging for eraser operations.
 * Default: true
 * */
public bool $eraser_logging = false;

/**
 * Set logger for model logs
 * */
public callable|LoggerInterface $logger;

Best practices

Logging: Keep logging enabled in development/staging;

Testing: Validate deletion flows, including parent relations and many-to-many detaches, before production.

Deny list: Extend eraser_base_deny_list to match your naming patterns for utility methods.

Mode choice: Use manual mode for sensitive domains (users, orders); auto mode for convenience on simpler models.

Ownership safety: Parent relations (BelongsTo, MorphTo) are skipped to preserve ownership chains and to prevent circular deletion loops.

Pivot hygiene: Many-to-many are detached; ensure pivot constraints and cascades are correct.

Model Relationships:

In order for Eraser (auto-discover) to recognize Model relationships the following is recommended:

• the return type must be defined
• the method must be public
• the method has no arguments

public function user(): BelongsTo
{
    return $this->belongsTo(User::class);
}

public function posts(): HasMany
{
    return $this->hasMany(Post::class);
}

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

Log Outputs Example

Info
[info] Processing: Post[42]
[info] Processing relation 'comments'
[info] Relation 'comments' processed

Skipped
[info] Skipping parent relation 'author'
[info] Skipping already processed Post:42

---

Warning
[warning] Missing 'erasable' on Post
[warning] Method 'likes' did not return a Relation

---

Error
[error] Relation 'tags' not found on Post
[error] Error deleting relation 'images': Call to undefined method
