I have this definition in my upgrade script using migrate
meta = MetaData(migrate_engine)
DeclarativeBase = declarative_base(metadata=meta)
maker = sessionmaker(autoflush=True, autocommit=False,
extension=ZopeTransactionExtension())
DBSession = scoped_session(maker)
DBSession.configure(bind=migrate_engine)
class MarkerGraphic(DeclarativeBase):
__tablename__ = 'marker_graphics'
id = Column(Integer, primary_key=True)
base_url = Column(Unicode,default="http://chart.apis.google.com/
chart")
class EventType(MarkerGraphic):
__tablename__ = 'event_types'
__mapper_args__ = {'concrete':True}
id = Column(Integer, primary_key=True)
name = Column(Unicode(60), nullable=False, unique=True)
def __unicode__(self):
return self.name
and when doing an upgrade, only the EventType columns are created in
the db (postgresql).
Is concrete not compatible with declarative?
