It seems there's a error in cookbook article:
http://webpy.org/cookbook/sqlalchemy
Original code snippet:
----
def load_sqla(handler):
web.ctx.orm = scoped_session(sessionmaker(bind=engine))
try:
return handler()
except web.HTTPError:
web.ctx.orm.commit()
raise
except:
web.ctx.orm.rollback()
raise
finally:
web.ctx.orm.commit()
----
It should be:
----
def load_sqla(handler):
web.ctx.orm = scoped_session(sessionmaker(bind=engine))
try:
try:
return handler()
except web.HTTPError:
web.ctx.orm.commit()
raise
except:
web.ctx.orm.rollback()
raise
finally:
web.ctx.orm.commit()
