Hi, I've a problem like this:
http://groups.google.be/group/sqlalchemy/browse_thread/thread/e3ff5bd168f5045a Now, I'am using sqa 0.3.10, and a very complex mapper estructure. orm.mapper(PrestacionGrupo, prestacion_grupo) orm.mapper(Prestacion, prestacion, properties={ 'grupo': relation(PrestacionGrupo), 'anexos': relation(Prestacion, primaryjoin=prestacion.c.parent_id==prestacion.c.pre_id) } ) orm.mapper(ConvenioEstado, convenio_estado) orm.mapper(Convenio, convenio, properties={ 'efector': relation(Efector, primaryjoin=Efector.c.efe_id==convenio.c.efe_id), 'estado': relation(ConvenioEstado, primaryjoin=ConvenioEstado.c.conv_est_id==convenio.c.conv_est_id, lazy=False), 'prestaciones': relation(Prestacion, secondary=convenio_prestacion, lazy=True) }, extension=ConvenioExtension() ) I create an instance of Convenio [ convenio = Convenio() ] I do, convenio.prestaciones.delete(obj_instance) for delete a object from "prestaciones" list. Now, if I delete one object only, this work fine, but if I delete many (i.e: two obj) that error ocurr when I call to session.flush([convenio]). .... File "C:\Python\Python25\Lib\site-packages\sqlalchemy-0.3.10-py2.5.egg \sqlalchemy\orm\dependency.py", line 372, in process_dependencies raise exceptions.ConcurrentModificationError("Deleted rowcount %d does not match number of objects deleted %d" % (result.rowcount, len(secondary_delete))) ConcurrentModificationError: Deleted rowcount 1 does not match number of objects deleted 2 Why with deleting one object from list work fine, but this fail if I delete two or more?. How I can solve this? Thanks in advance. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
