Thank you Guy to answer my question.
I know I can use the strftime property of datetime to format my dates
as:
qry.data_inizio.strftime('%d/%m/%Y')
but what I'm looking for, is a way to setting date style in SA or
psycopg2 whithout need
Hi,
Well, I see a model as a set of tables. In this particular case, a model is
the set of tables created with a particular MetaData object. I guess model
is a term from the MVC world, so perhaps there's a better term for SA users.

Hi.
I still do not fully understand cascade rules, however I want to be sure
the behaviour below is a feature and not a bug.
Here is the code:
from sqlalchemy import *
db = create_engine('postgres://manlio:[EMAIL PROTECTED]/test', echo=False)
metadata = BoundMetaData(db)
a = Table(
I wanted to experiment with using a MapperExtension to add a couple of
non-mapped properties to a class at load time.
def MyExt(MapperExtension):
def populate_instance(self, mapper, selectioncontext, row, instance,
identitykey, isnew):
print Hello World
# do some work here
return EXT_PASS

Did you intend for the B object to be able to not exist? I modified
your code to create a b object as
ah the mapper isnt taking into account the extensions that are local
to the query during the _instance() phase. we can add a ticket for
that.

well, just making an app in such a way that all the model classes
are attached to a single-datamember called model is just one of an
infinite number of ways to do MVC. so your app is sort of part of a
larger framework (whether that framework explcitly exists or not).

I was considering the use of migrate (http://erosson.com/migrate/) for
a new project using SA and I just wondered if anyone else is using
it? Are there any plans to integrate this support into a future
version of SA?
Thanks,
Allen

dont use the Unicode type if your MySQL client and/or server is
converting unicode for you. convert_unicode=False has no effect on
the Unicode type.
also note theres a bug in MySQLDB related to this:

...but it *appears* that when I start using

uh yeah...why would it be ? youre essentially pulling out the
original bind_to engine which has no idea about what particular
connection/transaction is

the fact that the deadlock was solved when I added the connection to

I'm using it, but then, I wrote it. It's worked well for me, though
I'm not sure how widely used it is... the mailing list is pretty
quiet.

heh, I was saying it backwards [lack of sleep] but this is what I was

Note that if the database supports an auto-commit feature, this must
be initially off. An interface method may be provided to turn it back
on.

Thanks a lot, guys. Will try a sample application and post in the wiki.
Might take some time - meanwhile, if somebody gets some more stuff,
posting it would help.

cities = cities.select(limit=1).execute().fetchall() works well with
this configuration, but leads to error in nregion =

if nregion = places.select(places.c.name == iv2).execute() used
