[Zope-DB] Process one PloneFormGen request into many SQL tables

[Dennis Schulz]

Hi,

if you want to do things like this, you also could use the alchmist product.
However, I think the archetype / plone formgen integration at the moment 
is not functional. (ask kapil t. and roché c. for closer info)
You would have to start out with plain zope 3 schema and formlib like in 
the alchemist included orgpeople example.
I developed a neat little application that uses the unit of work and 
automatic transaction support of sql alchemy and all dependent tables 
are deleted, updated and inserted automatically by the mapper 
(www.*sqlalchemy*.org/)
