clone_and_reset with relationships?

[James Masters]

I've been using clone_and_reset which is dead handy but it would be
handier still if, when it ran, it also cloned any sub-table
relationship entries, as well as the main table record. I can
implement it by hand but it's just a suggestion to add to the todo
list, if it doesn't already exist in some form.

thanks.

I'm actually working on a generic traversal helper right now. A
simple version of clone_and_reset_tree() (or whatever) might simply
Clone::PP the whole thing, then traverse the clone, calling
clone_and_reset() on each visited node.

Sounds perfect; I shall look forward, thanks very much.

any progress on this?  i am also looking for a "deep clone", but i guess it really would be more of a deep clone_and_reset.  (e.g. i wish to duplicate the entire structure and the values within, but all using new primary keys.)

looks like i should probably just continue to roll my own at this point.  but just curious -- seems like clone_and_reset_tree() would be a handy thing to have!

thanks,

Look at the as_* and new_from_* helper methods:
