i am following this tutorial http://scotch.io/tutorials/php/a-guide-to-using-eloquent-orm-in-laravel#sample-application

On this tutorial below code is use for routing a page with bread model & all the model related to it

// Route::get('eloquent', function() {

	return View::make('eloquent')

		// all the bears (will also return the fish, trees, and picnics that belong to them)
		->with('bears', Bear::all()->with('trees', 'picnics'));

});

but when i run this below error appear

Symfony\Component\Debug\Exception\FatalErrorException thrown with message "Call to undefined method Illuminate\Database\Eloquent\Collection::with()"

Stacktrace: #1 Symfony\Component\Debug\Exception\FatalErrorException in J:\server2\htdocs\practice\laravel\app\routes.php:18 #0 Illuminate\Exception\Handler:handleShutdown in <#unknown>:0

Now what should i do ???
