Ruby on Rails

Hello,

If I have a model A as :

name
address
phone

and model B as:

name
address
email

Is it possible to copy a record from A to B with one statement? I am
trying :

@a=A.find(2)
a_attributes=@a.attributes
a_attributes.delete "id"
@b=B.create(a_attributes)

@b.save!

And I am getting an exception :

unknown attribute: phone

How can do this without going through each attribute individually?

Thanks.
