Hi,
I'm trying to implement soft deletion in my app. I'd like to keep things
atomic so that if an error happens during the soft deletion process, I
don't get half deleted stuff.
Here is a simplified view of my code (full working example
here: https://gist.github.com/4329926):
class
I'd look at the python stdlib for examples, pickle uses __getstate__ and
__setstate__ (or sometimes __reduce__), copy I think uses __copy__, etc.
So per class hooks are one way, the other is to pass a serializer into the
target library, like:
mylibrary.serialize(object,

So the problem here is that the rollback does nothing, because there's a
commit in the delete_password method (in this example there's only method
called, in reality I have multiple methods). I think having stuff being

I've got some code where I want to assert that the ORM session is perfectly
clean. ie: I want to know if a flush() will emit SQL.
What is the best way to determine this?
Right now I'm simply checking like this:

the Session uses the method session._is_clean() internally to check if
going through the flush() steps is warranted, which is roughly equivalent
to the check you're doing, though it is doing less work to make this
Michael,

there's many levels this could be failing, and the first step would be to make
a raw PyODBC connection to the database, to see if there's any
incompatibilities there.
here's all the detail on how to do that:

Whoops - _is_clean() doesn't make it up to a ScopedSession...
Digging into why this is the case I see the registry pattern in there. Is
it a safe/valid cheat to access the registry directly and do this?

I have no problem at all with pyodbc and qodbc
Here is a sample I just did:
I include a call to connect without autocommit - which throws an error, and
then the one what works.
The error message is exactly the same one I get trying to connect
SQLAlchemy.
I do not know how to translate cx =
