I'm wondering what is the best way for a mapped object to acquire a
connection for a non-ORM style query while staying within the context
(reuse connection or transaction) of its own session. For example, here
is a method of a mapped object.
@property
def analysis_count(self):
"""Return a count of related analysis records.
"""
sess = object_session(self)
con = session.connect()
result = select([func.count(sample_analysis.c.id)],
sample_analysis.c.batch_id == self.id,
bind=con).execute().scalar()
return result
Is this correct and is there a better way to accomplish this? I'm
working with SA 0.3.10.
