GeoAlchemy is for SQLALchemy =0.7.x
GeoAlchemy2 if for SQLALchemy =0.8
Kamil is mostly right. GeoAlchemy2 v0.1 is published on PyPI now, and
GeoAlchemy(1) is also still available. The latter is still compatible with
SQLAlchemy 0.8 though, but GeoAlchemy2 has a much easier code base and
well .key on any ColumnElement is supposed to be a string name that Query and
others will call upon to assign it a label in the result set. removing .key,
which is unneeded, allows it to work (note expr.clauses):
class PGCompositeElement(expression.FunctionElement):
def __init__(self,
Hi Michael, thanks for the explanation on the key attribute. I ended up
misunderstanding it at first, but it seems to work now.
I had a few problems when I tried to use a UserDefinedType (e.g.
geoalchemys Geometry) in the typemap, because it complained about a missing
key attribute. I've

As far I'm concerned:

GeoAlchemy2 if for SQLALchemy =0.8
On PyPI is GeoAlchemy 2 version 0.1 working with sqlalchemy 0.8
With regards

Thanks for you help. Using the FunctionElement worked quite well, but
I had to tweak the constructor and assign the base parameter to

I've tried to extract the basic structure from this sample code and merge
it into the GeoAlchemy2 project, but somehow it fails to work for my

In general if you are using my recipe earlier that features ColumnElement,

just send me a standalone test script so I can see what you're trying to do

The output is SELECT (SomeFunction(table.foo)).attr1 AS anon_1, without

right, ColumnElement doesn't export the froms from it's expression by default.
There's a method you can implement to do this, but here is another approach
that doesn't use any private APIs:
from sqlalchemy.sql.expression import FunctionElement
