Topic: make a page that contains stuff from more than one model/controller?
I'm new to ruby and rails.
I've gone through different tutorials on using the rails scaffolding.
What I don't understand is how you make a page that has different sections that are each built from a different model/controller. Maybe the central section of the page provides the interface for a forum. And there is a sidebar that, say, shows the latest news topics for the site. Or another section that shows a random famous quote. Or whatever. The idea is how to have sub-sections of the page that are driven by their own data?
Is there a way to have the sidebar call into a different controller for its rendering? Or how is this done?
