Featured Items Listing

Hey All,

Say I have a website with articles and events and I want to create an index of featured items which will have a mixture of articles and events. I presume I'd create a FeaturedItem model/table with the following:

featured_class <-- 'Article' or 'Event' featured_id <-- id of Article or Event position <-- position in featured list

When I pull the featured items from the database, I'm gonna wanna pull the corresponding item from the featured_class table. What's the best way to do this, other than:

if FeaturedItem.featured_class == 'Article'   Article.find()... elsif FeaturedItem.featured_class == 'Event'   Event.find()... end

Is there anyway to create functionality that will allow me to do something like this:

FeaturedItem.featured_class.find()...

or something similar ???
