I am moving from version 1.0.14 to version 1.4.11 of sqlalchemy.
I need to get a callback when all of the data from orm query is loaded not just
single instance.
In the 1.0 version I created the session using query_cls:
self.session = Session(bind=engine, autoflush=False,
_enable_transaction_accounting=False, autocommit=True,
query_cls=my_query)
and the query class
class my_query(Query):
def _execute_and_instances(self, context):
results = list(super(my_query, self)._execute_and_instances(context))
rdbm_events.run_created()
for instance in results:
yield instance
def instances(self, cusor, __context=None):
results = list(super(my_query, self).instances(cusor, __context))
rdbm_events.run_created()
for instance in results:
yield instance
This does not work for 1.4.11.
What is the best way to get a callback when all
the data from query or lazy/deferred loaded into instances ?
