I did this in one of my previous projects.
what I did was to make a python module, with the right SQLAlchemy includes and
all the mapper objects. what I did not do is connecting to the database (it
makes the class module database independent)
What it does is it implements the iCal standard, it

Hi,
firefox uses sqlite to store bookmark info. The file is called
places.sqlite and the schema has type LONGVARCHAR for some fields and
LONG for another. Autoloading that with sqlalchemy maps that columns

How do people handle Decimal data with SA / SQLite? Newer versions of SA give
the following warning:
SAWarning: Dialect sqlite+pysqlite does *not* support Decimal objects natively,
and SQLAlchemy must convert from floating point - rounding errors and other
issues may occur. Please consider
Thanks Conor!
The callable works like a charm! It's great news! (I've been trying to
figure out this for 3 days... yeah... I guess I'm not that smart)
Now that I have it working, a “design” question pops up. Nothing
technical, really.

Hello, group!
I am still dealing with the relationship I asked before
(http://groups.google.com/group/sqlalchemy/browse_thread/thread/c1d46daf35116999).
To tell the truth, I'm not even sure if this is a question I should
ask in the SqlAlchemy forum because I'm also dealing with Megrok.rdb

Hi Dan
This is a little off topic for this group, however, I consider myself a
specialist in the area you question, so I'm delighted to be on the helping
end for a change :-)
We can continue this one-on-one outside the group. Send your questions to me.
I prefer Skype for this type of thing

I understand your question if you are getting different data from the
server in the two database accesses. But if you are loading the exact
same data twice for a page load, you should try to eliminate that
redundancy instead of finding a plan to perform the redundancy in the
best way.
