SoftDelete

Trait adding soft-delete support to a Model.

Instead of removing rows, delete() (by default) sets a deleted_at timestamp. find()/findMany() transparently exclude soft-deleted rows unless a SoftDeleteFilter is given.

Usage:

class Post extends Model {
  use SoftDelete;
}

$post->delete();                       // soft delete
$post->delete(soft: false);            // hard delete
$post->restore();                      // undo soft delete
Post::find($id, softDeleteFilter: SoftDeleteFilter::ONLY);
