concatenate columns from a database to one string?

That fourth parameter (where you have ":name") just specifies a method
to call on your object. So you can put any method in there, not just a
database attribute.

In other words, you could have the following method in your mode:

def summary
  "#{self.id}: #{self.name}"
end

and then pass :summary to the collection_select method, and it'll use
the values returned by that method to populate your options tags.

Whoops, I mis-counted -- I think it's actually the fifth parameter!
