Copy model instances in Rails

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

As per the following question, if you are using Rails >= 3.1, you can use object.dup :

What is the easiest way to duplicate an activerecord record?

This is what ActiveRecord::Base#clone method is for:

@bar = @foo.clone

@bar.save
