here's the relevant bit of documentation: http://www.sqlalchemy.org/docs/reference/orm/interfaces.html?highlight=mapperextension#sqlalchemy.orm.interfaces.MapperExtension.before_insert Column-based attributes can be modified within this method which will result in the new value being inserted. However **no** changes to the overall flush plan can be made, and manipulation of the Session will not have the desired effect. To manipulate the Session within an extension, use SessionExtension. so here you need to use SessionExtension as you'd like to manipulate the flush plan. > > Greetings and thanks for any hint, Torsten > > -- > DYNAmore Gesellschaft fuer Ingenieurdienstleistungen mbH > Torsten Landschoff > > Office Dresden > Tel: +49-(0)351-4519587 > Fax: +49-(0)351-4519561 > > mailto:torsten.landsch...@dynamore.de > http://www.dynamore.de > > Registergericht: Mannheim, HRB: 109659, Sitz: Karlsruhe, > Geschäftsführer: Prof. Dr. K.
