[Rails] Deep Copy Method?

[Thomas Counsell]

Sorry, just to clarify,

I guess I'm really trying to duplicate a set of rows in various 
database tables, to which the Rails ActiveRecord objects point.

I suspect (will check later) that Marshal.load Marshal.dump( self ) 
will just create a duplicate set of objects without duplicating the 
underlying table rows? or are Active Record objects cleverer than that?

Apologies for not being clear in my original post.
