Oh sorry my bad, i made it work. Thanks!

However, how to send custom methods from User too?

You would first need to get the Collection without the toJSON() and perform your methods, then use toJSON() on your method outputs.

$usersArticles = User::all()->with('Articles');

foreach($usersArticles as $userArticle) {
    echo $userArticle->myCustomUserMethod();
}

or

echo $userArticle->myCustomUserMethod()->toJSON();

if it outputs an object/array.

public function ajaxScroll() { $take = Input::get('take'); $skip = Input::get('skip');

	$articles = Article::orderBy('created_at', 'desc')
		->take($take)
		->skip($skip)
		->with('user', 'votes')
		->get()
		->toJson();

	return $articles;
}

How to do that in my case?
