Physical delete a model which is enabled softdelete in laravel5?

I am using SoftDeletes for a model in Laravel5.

But in some cases (Keeping history is not useful),I want to do physical delete (Removing row from table)instead of softDelete.

    class PaymentInvoices extends Model {

    use SoftDeletes;
}

Is there any method for forcing physical delete?

Of course there is. Use forceDelete method instead of just delete.

Keep in mind, forceDelete is only available if you use the SoftDeletes trait.

Example

$instance->delete() //This is a soft delete
$instance->forceDelete() // This is a 'hard' delete
