Hi all,
The following is a stripped down use case that I have, where I use
single table inheritance and run a query.first(), however I get a
deprecation warning and I was wondering why ??
Cheers
Dave

% cat db.py
from sqlalchemy import *
from sqlalchemy.orm import *
session = scoped_session(
sessionmaker(
autoflush=False,
transactional=True
)
)
mapper = session.mapper
metadata = MetaData()
myTable = Table(
'mytable',
metadata,
Column('id', Integer, primary_key=True),
Column('animate', Boolean, nullable=False),
Column('remoteid', String(50), nullable=False),
)
class MyTable(object): pass
class MyAnimateTable(MyTable): pass
myTableMapper = mapper(
MyTable,
myTable,
polymorphic_on=myTable.c.animate
)
mapper(
MyAnimateTable,
inherits=myTableMapper,
polymorphic_identity=True,
)
def connect(uri):
engine = create_engine(uri, strategy="threadlocal")
metadata.bind = engine
return engine
def create():
metadata.create_all()
def drop():
metadata.drop_all()

% cat test.py
from db import *
connect('sqlite://memory')
drop()
create()
klass = MyAnimateTable
Query(klass).filter(klass.remoteid == "fds").first()
