I have a table (T) that has a many-to-one relationship (via foreign key inclusion) to a category table (C). Let's name the relationship category. When I retrieve an existing T record, SA populates the category field with an instance of C. I can change the category to a different value by storing a different instance of C into category.
My question is does it matter if the various instances of C are associated with the same session as the T instance? Can the C instances come from a different session, or can the be expunge'd from the session that retrieved them? Can I store an entirely new C instance, and if so, will SA do an insert into the C table? Thanks, Mark -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
