Laravel force delete event on relations

问题

I'm developing a Laravel web app using Laravel 5.2. My question is very simple... How do I listen to a forceDelete event in order to forceDelete model relations?

I've been looking around the web and S.O. for a few but all the questions/answers I've found where releted to the delete method, and also in the API documentation I haven't found very much...

In my case I have a Registry model and a RegistryDetail model

Registry table

|id|name|surname|....

RegistryDetail table

|id|id_registry|....

I've created for both this boot function:

protected static function boot()
{
    parent::boot();

    static::deleted(function($registry) {
        // Delete registry_detail
        $registry->registryDetail->delete();
    });

    static::restored(function($registry) {
        // Restore registry_detail
        $registry->registrydetail()->withTrashed()->restore();
    });
}

Since both models have SoftDeletes the static::deleted function is called only when the delete() method is called. if I call a forceDelete() method the related model won't be deleted from the database.

If you need more informations let me know.

Thanks in advance

The deleted event should still fire when calling forceDelete(). Inside the deleted() event method, you can check the the forceDeleting protected property via isForceDeleting() to see if you're in a regular delete or a forced delete.

static::deleted(function($registry) {
    // Delete registry_detail
    if ($registry->isForceDeleting()) {
        $registry->registryDetail->forceDelete();
    } else {
        $registry->registryDetail->delete();
    }
});
