Issue using View()->Composer() in AppServiceProvider

I am trying to pass data to a view using the boot method in the AppServiceProvider, and have followed the steps outlined in one of the Laracast fundamentals videos. However, I am getting an error in my controller when trying to use this variable.

In my AppServiceProvider:

public function boot()
{
    view()->composer('home', function($view){
        $view->with('current', Post::orderBy('created_at', 'desc')->first());
    });
}

So this should pass the data to my home view as far as I understand, so that I don't need to keep referencing it in all the methods I have in the controller for that view. I then have a homeController with the following method:

public function index()
{
    //Get user
    $user = Auth::user();

    //OMDB API setup - Get Movie name, remove spaces, add into API request
    $movie_one = str_replace(" ", "+", $current->movie_one);


    $movie_two = str_replace(" ", "+", $current->movie_two);

    return view('home', compact(array('user')));

}

Previously I was adding a variable called current in this method to get an entry from my Post table, but wanted to add it to the AppServiceProvider as I will have to re-declare it in other methods as well. The issue I have is that I try to use the $current object again in this method, but it isn't available to it? I get the following error:

ErrorException in homeController.php line 30:

Undefined variable: current

What can I do here? Can I pass that data from to a controller as well as the home view? Or is that not possible?

the code you written inside the boot method, will only be accessible inside home view, if you want to access the Post object inside controller too, you have to follow this, through this you can access your Post object in controller, as will as view.

app()->singleton('current',function($app){
    return Post::orderBy('created_at', 'desc')->first();
});

So in your code, you can access the Post object like this, 

$post_obj = App::make('current');
$post_obj->movie_two;

or directly

App::make('current')->movie_two;
