Hi all,
I'm writing using Flask, Python 2.7.11, Sqlalchemy 1.0.11 and Postgresql
9.4.6 to write a web application but
I keep getting this error when I try to access the database. First, my
config file:
import os
basedir = os.path.abspath(os.path.dirname(__file__))
SECRET_KEY = 'chara'

Thanks Michael.

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 ha
the patch takes advantage of other improvements in 0.8 and would be
destabilizing for 0.7. it's a pretty major rethink of how join() works.

Hi Michael,
Sorry to be a pain, but will these patches be applied to 7.10?
My app needs a lot of mods for it to work in 8.0.
If not don't worry, I guess it is time for me to move on to 8.
I'll try it out this weekend.
Thanks

Hi Michael,
Thank you very much for your help and quick response.
The workaround worked.
I really like the simplicity of the query api that i automate the
generation of it.
I will try to incorporate the workaround.
Thanks again

Here's a technique you should be able to use as a workaround:
1. for every mapper that you're joining *to* which is also a joined inheritance
subclass, transform it into an aliased() construct
2. any join involving an aliased() construct, construct the ON criterion
manually.
These two technique
oh. this *fails in 0.7 also*. I thought this was a regression.Yeah, this
query is a little crazier than we've planned for, I can see the general thing
it's failing to do but will have to see what's involved to get it going. But
not a regression is good news at least.
On Apr 24, 2013,
this is logged as http://www.sqlalchemy.org/trac/ticket/2714 for further study,
this is an extremely complicated use case and I may have insight on it today,
or I might not have insight on it until next week.I will have to find the
time to look into it more deeply.

make sure the Session is closed when not in use. Make a new session when its
time to talk to the database again. This is in the notes for pool_recycle -
it works upon checkout from the pool.
