How do I access a global model instance in laravel 4?

In Laravel 4, how do I create an instance of a model and make it globally available? Even in views. I'm looking to do something similar to the way you get the User instance using Auth::User->name (the syntax I mean, not storing in a session) but in this case it would be ModelName::DefaultEntity->attribute.

A little more detail...

I am writing an application that will house multiple websites - a bit like a CMS. So I have a Website model. Each Website model will have a URL attribute so that when a user visits the URL the application can retrieve the Website model from the database and brand the website appropriately e.g. Title, logo, theme, etc...

I would like the current Website model to be available everywhere without having to create a new instance of Website in every controller/method. So in my layouts and views I could just say something like:

{{ Website::Website()->name }}

or 

{{ CurrentWebsite::name }}

I have achieved the first one by making a static method in the Website model:

public static function current()
{
    return Website::find(1); // just to test it for now
}

But with that, it will have to do a database query every time I say:

{{ Website::current()->name }}

Plus it doesn't feel right.

Can anyone help?

Kind regards,

Robin

What you already have is good, but if you just want prevent that query from executing every time, you can cache it:

public static function current()
{
    return Website::remember(10)->find(1); // just to test it for now
}

Adding a listener to your routes.php:

 DB::listen(function($sql, $bindings, $time) { var_dump($sql); var_dump($bindings); });

And executing it:

{{ Website::current()->name }}

Will show the query in the first execution but not in the second, because it's cached.

  1. Create normal class. Like CurrentWebsite or Website or whatever.

    class Website {
    public function a() {
      //your code
    }
 }

  2. Create facade (WebsiteFacade.php)

    use Illuminate\Support\Facades\Facade;

class WebsiteFacade extends Facade {

    protected static function getFacadeAccessor() { return 'website'; }

}

  3. Create Service Provider

        use Illuminate\Support\ServiceProvider;

    class WebsiteServiceProvider extends ServiceProvider {

    public function register()
    {
         $this->app->bind('website', function()
         {
              return new Website();
          });
    }
    }

4.Go to your config/app.php and add folowing:

 'providers' => array(
      'WebsiteServiceProvider'
 )

and 

 'aliases' => array(
      'WebsiteFacade'
 )

5.Refrech auto loader. And Now you can access Website class anywhere like this:

    Website::a();

You probably are looking for 'a shared container bind'. See the docs here.

<?php
App::singleton('foo', function()
{
    return Website::whereCode('whoop')->first();
});

App::make('foo'); // every where you need it
