I'm sure I'm missing something simple here, and any pointers in the
right direction would be greatly appreciated.
Take for instance the following code:

parents = session.query(Parent).options(joinedload(Parent.children)).all()
session.close()
print parents[0].children #

hope my approach isn't too simplist, but onetomany is usually implemented in

In the specific case you have above, you can also use a trick which is to use
contains_eager():
parents = session.query(Parent).options(joinedload(Parent.children),

Hi All,
Give the following model:
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.types import Integer
Base = declarative_base()
class Model(Base):
__tablename__='test'
id = Column(Integer, primary_key=True)
col = Column(Integer)
...the following code will

This relationship is satisfied as you request it, and it works by looking in

If I merge the updated channel like you can see in this piece of code
it's working:
def insertXML(channels, strXml):
Insert a new channel given XML string
channel = Channel()
session = rdb.Session()
channel.fromXML(strXml)

Yes, I've done that. I doesn't work either.
for chan in channels:
if chan.id == channel.id:
chan = session.merge(channel)

Suppose this is my table:
a_table = Table(
'a_table', metadata,
Column('ts',Integer, index=True, nullable=False),
Column('country',String, index=True, nullable=False),
Column('somestat',Integer,nullable=False),
Thank you!
I figured a compile visitor might be the right way in, but had no idea
of how to do it!
Some tutorials just on the visitors would probably explain a lot about
how PG works!
Cheers!

So, there is a slight wart here:
q = select(Partition(t1,'myt1'))
