something I can identify what it was.

A few months ago I watched a video conference where Mike demo'd some
optimizations for SQLAlchemy when using EAV schemas. Does anyone know if
these optimizations will make it into the product that we have access to?
I'm about to start a large EAV based project with SA and I was curious.

Good to hear!
I took a look at #2694 and it seems that using column.contains(other,
autoescape=True) might get wordy fairly quick when -- at least in new
applications -- it would be a handy default. While it's probably not
particularly feasible, it'd be handy if the default for autoescape cou

So today I identified a small bug in my code and then, while trying to
resolve it, came to a few realizations:
1. column.contains(str) does not escape characters in str such as % and _.
Presumably, column.startswith(str) and column.endswith(str) have the same
behavior.
2. There is a distinct

this is a reopen of http://www.sqlalchemy.org/trac/ticket/2481, and is fixed
again in r7699a1080742. Thanks for the report.

that can't be guara
I have the following code:
from sqlalchemy import *
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import Session, relationship, backref
e = create_engine('sqlite:tmp/test.db', echo=True)
Base = declarative_base()
Base.metadata = MetaData(e)
class Node(Base):
This solution seems to work in my context
Thanks

Hi All,
I'd like to wire in a listener for before_insert for all models that use
a particular mixin. I may need to construct the listener based on some
columns in both the mixin and the model that mixes it in.
Do I use declared_attr and __declare_last__?
Are there any examples around of doin
Hi All,
If I do:
obj = session.query(MyModel).one()
obj.attr = 'something'
session.add(MyModel(attr='else'))
session.commit()
...does sqlalchemy guarantee that the update will happen before the insert?
cheers,
Chris
