The following test fails in 0.6.4 but not 0.6.3 with AttributeError:
type object 'Person' has no attribute 'foo'. Is this a deliberate
change? It seems a bit weird that every @classproperty on a
declarative subclass is accessed/run on import.

Can you explain why you'd want to do something like this?

I've got database with auto increment column called `id` and INSERT
query, whom I need to execute without model declaration in project.
meta.Session.execute() returns ResultProxy, but last_inserted_ids()
doesn't work with execute() and SELECT LAST_INSERT_ID() statement
sometimes return 0. Is there
SELECT LAST_INSERT_ID() is ultimately where the value comes from - the raw
.lastrowid is present on the ResultProxy for those DBAPIs which support it, so
try using that. Perhaps you're getting 0 because the transaction is going
away, in which case .lastrowid should solve that issue.

You mean something like this:
import sqlalchemy.types as types
class CHAR(types.TypeDecorator):
'''Strips padding from CHAR types.
'''
impl = types.CHAR
def process_bind_param(self, value, dialect):
return value
def process_result_value(self, value, dialect):
This is driving me crazy since I can't even get through the tutorial :

Hi,
I'm using SqlAlchemy 0.6.3 and PostgreSQL 8.4 and I'm trying to setup
a cascading delete between several levels of tables. The problem seems
to be that I can't have a relationship with cascade=all and a column
with ForeignKey that has nullable=False.
Here is my example:

no its not a column on a row, its on the ResultProxy:
result = session.execute('...')
id = result.lastrowid
