Laravel Model Eager Loading And Ordering

I'm new to Laravel and thought it be cool to purchase the Codehappy ebook by Dayle Rees.

I just finished the blog tutorial and thought a bit on how he retrieved the posts from the Post model. Coming from a .net (ASP.NET MVC) background I think it will be important to order the posts while eager loading the author.

He eager loads the model like this.

$posts = Post::with('author')->get();

My question is where can you use the "order_by" clause? the order_by itself works when I use:

$posts = Post::order_by('id', 'desc')->get();

Regards RaVen

I manage to solve it by:

$posts = Post::with('author')->order_by('id', 'desc')->get();
