I would be curious to know if this is actually a bug in event handling
though.

I've got a problem with SQLAlchemy 0.9.8 with a Routing Session setup and
using the query count method.
I started from this post on Mike Bayer's
blog:

I did some tweaks such that I could specify the database eng

API, but the `connect` event does not give me a Connection to execute the

W/ psycopg2, you can do a cursor.execute(query, list) where list is an
actual python list of values : [1,2,3]
W/ SQLAlchemy, it seems the session.execute(query, values) will only
accept a dictionary for values. Am I missing something? Can I pass a
list instead? Thanks.

Figured it out. I had two self-referential foreign keys on the table,
both pointing (obviously) to the primary key, but for some reason I
was specifying foreign_keys to the relations, I just removed these
arguments to the relations and this has resolved itself.

Hi,
I am just wondering if it is possible to allow a declarative object to
have some of its properties comparable as if they were ClauseElements.
I know I'm not explaining myself terrifically well here, but consider
the following property:

def is_visible(self):

I have some code that is taking values out of one database (a MySQL
latin-1 database) and inserting them into another (postgres, utf-8)
database, and I can't for the life of me work out what is going wrong
here. The traceback looks slightly fishy, so I can only assume
something is going horribly wr
m as the same attribute on the
mapper, but I really need the ability to query against that column
across the different mappers (without having to do an OR). Is there a
way around this?
Any help would be appreciated :)

Sorry to bug… I imagine there is no way of doing this, but would be
good to know for sure. If not, this would be really useful
functionality. For instance, I might want to populate one column based
on the contents of one of more other columns.

know as that's the best way to do it, but it does eliminate a lot of
try...except...else's since I do need the explicit subtransaction
stuff.
In any case, thanks for clearing that up for me, and it's good to know
about those accessors.
