Hi all,

I have a question regarding the duplication of a model and it’s  
associations. For example, if I have ModelA and it has\_many SubModelAs  
and has\_many SubModelBs associated with it. Each of the SubModels a  
belongs to ModelA. Is there a quick way of copying ModelA and the  
structure that lays below it? In the end I’ll then end up with ModelB  
which is a copy of A, and it has copies of SubModelA and SubModelB  
records.

Cheers,  
Diego
