Starting with r2598, I'm seeing some failures with how I'm using the
association proxy. I've modified the
examples/association/proxied_association.py file which duplicates the
problem.
It is possible that I'm not suppose to remove associations like I am.
But it did work before (in 0.3.7 and
Ive added ticket #597 for this.

Would you write a failing test for this condition? I looked at the
unit tests but wasn't able to make a failing test. So that is why I
modified the example.
I also tried to formulate a work around. And failed at that as well.

FWIW I'm +1 on removing the old-style methods, +1 on .first instead of
.scalar, +1 on adding .one, and +0 on renaming .list to .all.
Did you make a decision for 0.4 Mike?

Hi,
Anybody knows how I could emulate the behavior of Query.get (ie get
the result from the session if possible instead of always fetching
from the db) if I have the values for the different columns of the
primary as keyword arguments (ie not in the order of the columns of
the initial table)? I
the legal way is the association_proxy and family.
here another shorter ... a hack:
i did have similar need - obj.somerelation.append( left=.., right=..),
so i did monkeypatch the InstrumentedList's append to use the item
returned from collection's append -
def append( self, *args,
actually, I am iterating through all the databases in the meta
ti = model.meta.table_iterator()
for t in ti:
print create %s ? % t
if raw_input(Choose [Y/n]).lower() in ['y','']:
t.create()
I want to be able to chose which database to create from a pool on
Using the association_proxy extension in combination with your
dictionary collection class is an easy way to get this kind of
simplified access. Assuming your Attribute's value is in a
property called 'value', you can set up simple dict access like so:
class Obj(object):
attrs =

Here is my dictionary collection_class:
class AttributeDictNEW(dict):

def append(self, item):
The association proxy will take care of Attribute construction for
you, so you can get away with just:
class AttributeDictNEW(dict):
def append(self, item):
self[item.key] = item
def __iter__(self):
return self.itervalues()

Hello all
I am experimenting with SA on MSSQL and am having difficulty with
table reflection as outlined in the tutorial, for instance:
from sqlalchemy import *
db = create_engine('mssql://login:[EMAIL PROTECTED]/db')
metadata = BoundMetaData(db)
users_table = Table('users', metadata,
Just tried it here on a Linux + pymssql box and it worked fine.
The 'NoSuchTable' error would indicate that the table is not found, as you
surmised. Check to make sure the table is really persisting after your first
session with the table create. In the meantime, I'll see if I can get

Works in Windows, too, sqlalchemy 0.3.8, Python 2.5, pymssql 0.8.0, MSSQL
2005
Try upgrading your pymssql if you're not at 0.8.0. If that won't work, then
I would suggest a switch to pyodbc

So all of the above was done with Windows XP, Python 2.4.3, pymssql
0.7.4, and MSSQL 2000. I upgraded to pymssql 0.8.0 with the same
results. I uninstalled that and installed pyodbc 2.0.3.6, same
results.
The obvious differences between my installation and yours is that I am
using MSSQL 2000

Thanks for all the quick replies. Currently on pyodbc 2.0.3.6.
Anyway, I tried this (the table 'zones' most definitely exists):
metadata.engine.echo = True
zones_table = Table('zones', metadata, autoload=True)
2007-06-12 18:20:40,924 INFO sqlalchemy.engine.base.Engine.0x..b0 SET
nocount ON
That looks OK to me.
Try pasting that query (cleaned-up) into a query window on Enterprise
Manager and see what kind of results you get. The ? arguments are
positional, so the first would be the table 'zone'; the second the schema
'dbo'.
