Wrong. find :all returns an empty array (which you could test with
foo.empty? ). find :first (or things like find_by_xxx) return nil (and
find(xxx) raises ActiveRecord::RecordNotFound if there is no record
with that id)

Your variable will be nil.

EG

@accounts = Account.find(:all)

if there are no records @account will be nil.
