activerecord - Copy model instances in Rails

Question

I have a model Foo with attributes id, name, location. I have an instance of Foo:

f1 = Foo.new
f1.name = "Bar"
f1.location = "Foo York"
f1.save

I would like to copy f1 and from that copy, create another instance of the Foo model, but I don't want f1.id to carry over to f2.id (I don't want to explicitly assign that, I want the db to handle it, as it should).

Is there a simple way to do this, other than manually copying each attribute? Any built in functions or would writing one be the best route?

Thanks
