How to route child resources on Laravel 4?

Question

So I writing a simple app that has nested resources: posts and comments. Naturally, posts are parents, comments are children, related each one to one post. Simple enough. Now I want comments index (and creation, POST) page to live at posts/{post_id}/comments, update (PUT) to live at /posts/{post_id}/comments/{comment_id}. So I tried this:

Route::resource('posts', 'PostsController');

Route::group(array('prefix' => 'posts/{post_id}'), function() {
    Route::resource('comments', 'CommentsController');
});

But it won't work since the route name is registered as posts.{post_id}.comments.create. Basically the post_id placeholder is counted as part of the route and it's not neat. Any way of doing this nicely or should I just write routes one by one and get rid of the group/Route::resource/prefix thing?

You can use nested resources like this;

Route::resource('posts', 'PostsController');
Route::resource('posts.comments', 'CommentsController');

When you php artisan routes you will see your new routes;
