What is the best way to assemble a view with data from several models?

Question

Laravel

There is a small blog site on Laravel. Models Post and Comment, and respectively. PostsController and CommentController I show
the main page through the index method

$posts = Post::all();
        return view('blog.index', compact('posts'));

Page with a specific post via the show method

return $post ? view('blog.show_post', compact('post')) : abort(404);

in PostController. It is necessary to display comments to it on the page of a specific post.
Is it possible, and to what extent it will be correct in the PostsController show method to also access the comment model? Is this the correct use of a controller, doesn't it violate MVC principles?
A little confused.

Answer 1

For me, the controller and the model may not be related at all. You can call many models from one controller, and that's fine.
