I defined a model with several DB mapped entities. Here's one of them:
...
address_table = Table("address", metadata, autoload = True)
...
class Address(object):
pass
...
assign_mapper(session.context, Address, address_table)
Then in the controller an instance of Address class is modified ans
saved:
# 1. construct/read object
a = Address.get(address_id)
...
# 2. modification of object a properties
...
# 3. save changes
a.save()
a.flush()
All of 1., 2. and 3. use the same connection for interaction with the
DB.
I need to run my custom query in that connection before 3. executes.
How can I get that connection?
Thank you.
