The most "right" way from Ruby documentation is to use u.class.name Updated: the answer - u.name.to_s that was selected as correct - not right, cause:
for example:
class A
def self.to_s
"BBB"
end
end
ruby-1.8.7-p302 > a.class.to_s
=> "BBB"
ruby-1.8.7-p302 > a.class.name
=> "A"

If you want to get the class name, try:
u.class.to_s
Edit:
As Sergey pointed out in his answer it is better to use
u.class.name
I believe that is because to_s could be overwritten and it could possibly return a different string that the one returned by name.

Try u.inspect and see if any of that info fits your needs.
