The intent is to provide a single point of commit responsibility, an automation of a commit for a successful request and a rollback for a request that causes an exception. The actual technology used to do that is not really really that important; it happens to be repoze.tm2 and ZopeTransactionExtension. If you want the double whammy of inconvenience of not having your changes committed for you and you want to write code that commits before the request is finished (perhaps too early, when the request isn't actually known to be "successful"), you can disable it. ;-) - C > > Thanks a lot, > > -- > Eric Lemoine > > Camptocamp France SAS > Savoie Technolac, BP 352 > 73377 Le Bourget du Lac, Cedex > > Tel : 00 33 4 79 44 44 96 > Mail : [email protected] > http://www.camptocamp.com > -- You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
