sorry don't see this post, thanks for answer.

I don't know too how to trigger created event., but i try to understand how to edit function method work find in youtube, and after read function i write in my store function in controller admin

/**
 * Store a newly created resource in storage.
 *
 * @param  Request $request
 * @return Response
 */
public function store(Request $request, FileRepository $FileRepository)
{
    $entity = $this->testimonial->create($request->all());

    $entity->files()->attach($request->medias_single['gallery'], [
        'imageable_type' => 'Modules\\Testimonials\\Entities\\Testimonial',
        'zone' => 'gallery',
    ]);
    flash()->success(trans('core::core.messages.resource created', ['name' => trans('testimonials::testimonials.title.testimonials')]));
    return redirect()->route('admin.testimonials.testimonial.index');
}

It's work, now when i create a new testimonial, a new row is create in table media__imageables.
But i don't know if is a good way to do it.

I try to create a new module with The module scaffolde find in https://asgardcms.com/docs/v1/workshop-module/module-scaffold, but in the last question he ask a 'value objects'.

I have no idea what is it, when, why, where we can use it? have you any exemple to help me to undrestand please?

How i can't create a new page with a custom url ?

for exemple i want a new page to show any post by tag.

But if a create a new route, and controller and view i can't manage it in module page.
And if i create a page from module page i need to create as many page per tag, and if i have a new tag i need to create a new page, so it's not like a good idea.
