Re: separate class that prepares an IteratorAggregate object for View layer - where to place this?

Hi Thomas,

let me state my concerns here. Perhaps you can tell me if your
suggested answer is still good for the scenario.

I have various models and controllers.

Cars, Trucks, Tables, Chairs, Users, Passengers, etc.

I have admin actions: Admin_view, admin_edit, admin_add,
Actions for public are view, edit, add, etc.

I will use Twig for Themes on views that are for public consumption.

And i will not expose all the data models for designers to manipulate.
Just to be clear, i will expose only cars, trucks and passengers in
their respective index page.

1) Having said this, the IteratorAggregate class should still be in
app lib?

2) the Controller::beforeRender you would mean in cars, trucks and
passengers controllers only right?

3) so far your idea sounds good as i typed this response. I am liking
it.
