Hi there,
Using SQLAlchemy 1.0.9
I am dealing with some legacy code and came across the following issue. It
appears that in a polymorphic relationship SQLAlchemy is not able to
correctly determine what to load for a relationship when using a subselect
(due to limit on query) and child class
Hello,
I'm curious about the behaviour of foreign keys when modifying collections
as I want to be able to get the value before flush for some business logic
validation.
The following is a cut down version of the association list example:
import uuid
from sqlalchemy import Column, ForeignKey,
Hi there,
Quick question - is it possible to get a custom comparator to work
with order_by?
At present my code based on SA/examples/vertical/dictlike-
polymorphic.py raises a NotImplementedError when attempting to use the
value in an order_by statement.

Thanks as always for the quick response and fix.
As a slight aside; I am using a MapperExtension to create an attribute
on an object. When the object is stored, reloaded and then merged back
into a session this attribute is no longer available.
Any thoughts on why this might be?

Hi there,
In SA 0.4.6 I get the following failure when attempting to merge an
object that contains a ComparableProperty:
prop.merge(self, instance, merged, dont_load, _recursive)
TypeError: merge() takes exactly 4 arguments (6 given)
Is this something I am doing wrong or a bug?
ta,

Hmmm...I read your last mail as populate_instance works better in
0.5, but looking again I see that wasn't what you meant.
As it is I just left my code as is and after upgrading to 0.5 it just
worked...

Ah, apologies Michael - I should have mentioned that I am using the
svn 0.5 checkout.
In 0.4 it does raise NotImplementedError.
In 0.5 it causes a recursion error.
I understand that the working copy will be more susceptible to bugs
etc so please take this as a note rather than a major issue.

Hi there,
Just came back to some code after a bit of a break and can't seem to
get my head around how to correctly use the in_ method with a custom
comparator
That makes sense - thanks again.

Hi Michael,
As expected the trunk works perfectly.
I am also looking into the comparator example you pointed to as this
looks like it will help with a couple of other implementation details
as well.
Thanks again,
Martin

hey mike,
Just to confirm - trunk fixes problem with deletion.
Additionally, I have removed the lazy loading condition and it
maintains the speed of the query.
Thanks again to the team,

Hi there,
I have been using sqlalchemy for the past month with great success.
However, recently I came across an unexpected situation. Essentially
the results I was retrieving from the database via an ORM query were
not including all the related attributes despite indicating eager

Ah, thanks for the quick response Mike - I'll keep an eye out for the
