Better than a long speech, here are two files (eagerloading1.py,
eagerloading2.py) which, I though, were supposed to do the same thing.
Indeed, the difference is that in the first file, the polymorphic_identity
is hard coded and in the second file, it is set dynamically afterward (like

I dont' have an example specific to ARRAY handy, did you read the documentation

I've isolated what's happening here, but please send me scripts that generate data next time so that I don't need to take the time to reproduce all of this.the issue is not related to eager loading, it has to do with a many-to-one load of TaxonRelationship.referenced_taxon should pull from the
can you pass along a short code example? I can try to edit it.

Thank you very much for your quick answer.
I did provide the file test-data.sql that generates data. Didn't you see it
or maybe would you like something different next time?
Thank you

here you go, note MutableList is copied from MutableDict except adapted for
lists, works as advertised (you'd need to add other list methods besides
append()):

Great! I'm gonna check it out :)
Thanks!

Hi Michael,

Hello there,
When this application starts, we reflect the DB into a MetaData() object
and this is made available for everyone to use.
I'd like to add a few more methods to the table objects within that
MetaData(). Is there any easy way to extend these already
instantiated
You'd probably implement your own reflect_all function/method:
from sqlalchemy import inspect
def reflect(metadata, bind):
inspector = inspect(bind)
for tname in inspector.get_table_names():
MySpecialTable(tname, metadata, autoload=True, autoload_with=bind)

oh, except you might have problems with tables in there that are reflected due
to a foreign key.Table is not really intended for subclassing, unless you
want to do SQLAlchemy-Migrate's approach of monkeypatching Table.__bases__ at
the global level, I'd seek some other way to achieve what
Thanks for the reply Michael... I had a hunch this wouldn't be easy to
tackle, but this is more than I can chew at the moment: )
For now, I'll just keeping doing what I'm already doing which is to
instantiate a new class taking the table as an argument, and then within my
class reference the

def __lt__(self, other):
