How to modify the created_at date time through the controller

@Nakov - Sorry but not looking for how I would update it, only display it.

@hjortur17 Then why don't you do this only:

$post->created_at->locale('is_IS')->isoFormat('Do MMM YYYY');

@Nakov - I'm using VueJS, so somehow I would need to transform this on the backend.

@Snapey - Change the way it is displayed.

@hjortur17 So its normally cast to a Carbon instance, why are you converting it again?

@Snapey - I want to have it on this format Do MMM YYYY and really don't want to be installing and importing DayJS or MomentJs to format the string in my Vue component.

I have been doing this like this:

public function index() {
        return Inertia::render('Homepage', [
            'posts' => Post::query()
                    ->when(Request::input('leita'), function ($query, $search) {
                        $query->where('title', 'like', "%{$search}%");
                    })
                    ->with('tags')
                    ->get()
                    ->transform(function ($post) {
                        return [
                            'slug' => $post->slug,
                            'title' => $post->title,
                            'author' => $post->author,
                            'created_at' => Carbon::createFromFormat('Y-m-d H:i:s', $post->created_at)->locale('is_IS')->isoFormat('Do MMM YYYY'),
                            'content' => $post->content,
                            'img_url' => $post->img_url,
                            'tags' => $post->tags
                        ];
                    }),
            'filters' => Request::only(['search'])

                    // Ef ég bætti við ->paginate(*), þá þarf ég að gera eftir það ->withQueryString()
        ]);
    }

But I'm not sure how I can format the date when I have my query like this:

$post = $tag->posts()->where('slug', $slug)->with('author')->with('tags')->firstOrFail();

        return Inertia::render('Post', [
            'post' => $post
        ]);
