Laravel 5.2 'Master Layout' Variable passing - php

Question

So here is what I'm trying to achieve. I have a default blade template default.blade.php which is extended by all of my child views.
Within my default.blade.php i have a foreach loop which expresses some 'global' options to the user, and example of which is below.
#foreach ($projects as $p)
<li><a href='$p->project_uid'>{{ $p->project_name }}</a></li>
#endforeach
So to achieve this I'm having to pass the $projects variable via the view('viewname', $data) or via View::share('projects', $projects); in my Controller __construct()
Is there a better way for me to do this on a global sense so that the above calls don't need to be made?
One option i am aware of is calling a Model function from within my view, but this defies the concept of MVC so is not ideal.
Any guidance on the subject would be appreciated, Thanks.
Edit 1
So i tried the ViewComposer solution but ran into a couple of problems.
Below is my Composer & the Service Provider Register.
Config/app.php
App\Providers\ComposerServiceProvider::class,
ComposerServiceProvider
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class ComposerServiceProvider extends ServiceProvider {
/**
* Register bindings in the container.
*
* #return void
*/
public function boot() {
// Using class based composers...
view ()->composer ( 'default', 'App\Http\ViewComposers\MasterComposer' );
}
/**
* Register the service provider.
*
* #return void
*/
public function register() {
//
}
}
MasterComposer
<?php
namespace App\Http\ViewComposers;
use Illuminate\View\View;
use App\Repositories\UserRepository;
use Sentinel;
use ProjectUsers;
class MasterComposer
{
protected $users;
public function __construct(ProjectUsers $users)
{
$uid = Sentinel::getUser()->id;
$this->users = ProjectUsers::where("user_id", '=', $uid)->get();
}
public function compose(View $view)
{
$view->with('projects', $this->users);
}
}
Am i missing something obvious as it doesn't seem like the Composer is being loaded at all.
Edit 2
Fixed it myself. Realised that within the ComposerServiceProvider i need to specify a full path to my view like so.
view ()->composer ( 'admin/layouts/default', 'App\Http\ViewComposers\MasterComposer' );
Now it Works :D

Yes, you do this with View Composer.
View composers are callbacks or class methods that are called when a
view is rendered. If you have data that you want to be bound to a view
each time that view is rendered, a view composer can help you organize
that logic into a single location.
Bind that data to defualt.blade.php view, like:
public function compose(View $view)
{
$data = .... // Get data here.
$view->with('projects', $data);
}
