Here's my issue: 3 tables
CREATE TABLE accounts (
account_id serial PRIMARY KEY,
name varchar(16) NOT NULL UNIQUE,
);
CREATE TABLE transactions (
transaction_id serial PRIMARY KEY,
);
CREATE TABLE entries (
entry_id serial PRIMARY KEY,
account_id integer NOT NULL REFERENCES

I get the same result with this in 0.3.10 and 0.4beta5
Basic idea: I have two tables which hold various data and a third
table which let's different rows in each table be related to another
(many-to-many relationship).
Table/ORM code:
base_table = Table('base_type', metadata,

I've done some more playing here and I think I can see why the
multiple contains_eager options dont work on a self-referential
mapping.
Here's my example again:
ali = trees.alias()
ali2 = trees.alias()
statement = trees.outerjoin(ali,
and_(trees.c.node_id==ali.c.parent_node_id,

Ive uploaded the script eagerload_all.py that reproduce the issue.
Hope it helps you.

its actually not eager loading the second list of accounts
If there is no eager loading on the second list, I don't understand
why a 'SELECT entries ...' is executed when I just
ask account.name and not account.entries.
untested, i.e. join_depth on a mapper thats not self-referential,

Hello,
I am saving to my column in this way. How do I get the primary key id
back from database?
z=User()
z.LASTNAME='smith'
z.FIRSTNAME='joe'
z.save_or_update()
z.flush()
How do I get my z.USER_SID which is my primary auto increment key in database.

Hello -
Over here at SQLAlchemy labs, we have a new branch available against
0.4 which I am considering merging (well, most of it will probably be
merged regardless for architectural cleanup purposes, but theres one
particular feature in question). The primary behavioral change is
that the
Is there any chance of making it an option to not
have a weak reference ?
How about something on the session level with sessionmaker ?
Having it the session level would help me but not sure if make sense there.
I have things in the model object that depend on the object not going
away. I have
You should find it at z.USER_SID after the flush.
Not sure about your save() and flush() calls howevershould be
session.save_or_update(z) and session.flush()

You probably need to override the autoloaded primary key column:

Specify the type with MSUniqueIdentifier from
