I am looking to adapt this code for a related array/type issue. The code
from https://gist.github.com/4433940 works just fine for me (as expected)
when building/executing the stmt directly, but not when using the ORM.
When row is created using ORM, like this:

s =
this is ticket http://www.sqlalchemy.org/trac/ticket/2648 and cannot be worked
around at this time. If you're working with arrays of UUID I'd recommend
using psycopg2 type processors, as the previous poster has had success with.

correction, this seems to work, though will try to improve:
class UUID_ARRAY(TypeDecorator):
impl = ARRAY(UUID, dimensions=1)
def bind_expression(self, bindvalue):
if bindvalue.callable:
val = bindvalue.callable()
else:
val = bindvalue.value
change again, that doesn't work.
Upon reflection, I think the case here is that there's no alternative but to
make sure psycopg2 can properly format the contents of the ARRAY itself. This
is because SQLAlchemy is producing a completed INSERT statement for
preparation, without the parameters
Thanks for the follow up.
Upon further reading/reflection, I discovered that wrapping my string IP
address values in the psycopg2.extras.Inet object and then passing that in
-- and executing psycopg2.extras.register_inet() as with the UUID example
-- seems to work fine for both ORM and

related records inside a related property list. I thought it was

My problem was that I'm not closing the session properly.
My new question is... is there a way to autoclose the session? My example, at
the end of the scope?
What's the recommend way to do this?

Tried to replace this with this, but results are the same
temp1 = p.children[1]
temp2 = p.children[2]
p.children[2] = temp1
p.children[1] = temp2

Hi,
My SQL is like select host, count(*) as cnt from tbl group by host order
by cnt desc
How to achieve this using ORM?
session.query(Tbl.host,
func.count('*').label('cnt')).group_by(Tbl.host).order_by(???)
I don't wanna type again func.count... in order_by().
Thanks.

You received this
assuming you can try 0.8 which provides inspect(), this will show what is
happening:
from sqlalchemy import inspect
print
p.children[2] = c2
print p.children
print inspect(c2).attrs.parent.history
print inspect(c3).attrs.parent.history
print
