The include trick is not efficient. I keep the companies in a cache. Mostly, my point is to be aware of all the magic that Ruby is doing. The easy stuff works great when you start off, but you will want to watch the database calls. I use that trick for other things, but I have 30,000+ companies in my database.

In your controller you could have something like @people = Person.find(:all, :include => :companies When using active record in your views, it won't need to make the db call because rails will keep the join information in memory. Depending on how many records there are, you will probably see a significant increase in speed. Hey Dave,
