Sometimes you may want to periodically delete models that are no longer needed. To accomplish this, you may add the
Illuminate\Database\Eloquent\Prunable
or Illuminate\Database\Eloquent\MassPrunable
trait to the models you would
like to periodically prune. After adding one of the traits to the model, implement a prunable method which returns an
Eloquent query builder that resolves the models that are no longer needed:
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Prunable;
class Flight extends Model
{
use Prunable;
/**
* Get the prunable model query.
*
* @return \Illuminate\Database\Eloquent\Builder
*/
public function prunable()
{
return static::where('created_at', '<=', now()->subMonth());
}
}
When marking models as Prunable
, you may also define a pruning
method on the model. This method will be called
before the model is deleted. This method can be useful for deleting any additional resources associated with the model,
such as stored files, before the model is permanently removed from the database:
/**
* Prepare the model for pruning.
*
* @return void
*/
protected function pruning()
{
//
}
After configuring your prunable model, you should schedule the model:prune
Artisan command in your application's
App\Console\Kernel
class. You are free to choose the appropriate interval at which this command should be run:
/**
* Define the application's command schedule.
*
* @param \Illuminate\Console\Scheduling\Schedule $schedule
* @return void
*/
protected function schedule(Schedule $schedule)
{
$schedule->command('model:prune')->daily();
}
Behind the scenes, the model:prune
command will automatically detect "Prunable" models within your application's
app/Models
directory. If your models are in a different location, you may use the --model
option to specify the
model class names:
$schedule->command('model:prune', [
'--model' => [Address::class, Flight::class],
])->daily();
Notice: Soft deleting models will be permanently deleted (
forceDelete
) if they match the prunable query.
Mass Pruning
When models are marked with the Illuminate\Database\Eloquent\MassPrunable
trait, models are deleted from the database
using mass-deletion queries. Therefore, the pruning
method will not be invoked, nor will the deleting
and deleted
model events be dispatched. This is because the models are never actually retrieved before deletion, thus making the
pruning process much more efficient:
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\MassPrunable;
class Flight extends Model
{
use MassPrunable;
/**
* Get the prunable model query.
*
* @return \Illuminate\Database\Eloquent\Builder
*/
public function prunable()
{
return static::where('created_at', '<=', now()->subMonth());
}
}
