Comparing created at

I set up a simple blog in my rails app and on the forum index page
would like to display when the most recent activity was.

I have two table in my database, one for posts and the other for
replies.

My question is, how can I compare the created_at tags for two
different models?

I need some sort of conditional statement like

<% if forum.topic.last.created_at < forum.replies.last.created_at %>

and then display the most recent activity.

Any ideas much appreciated,

Dan

Something like that is fine. What's stopping you from going ahead and
doing that ?
