[Zope-DB] rollback / commit inside DTML : How To ??

[Harald Koschinski]

Hi,

does anybody know, howto commit / rollback a DB-transaction inside a DTML-Script by hand.

Something like
<dtml-commit>  :-))

I know the python functions (get_transaction().commit() ...) but how can I call this from DTML ??

regards
Harald
