However, the reason that I want to use expire instead of refresh is because there may be places in my code where the same object will be expired multiple times before an attribute is accessed, and I if I were to change all of my calls from expire() to refresh(), then it would hit the database multiple times. Basically, I want to know if there is a way to expire an object such that it will reload all attributes (scalar and eagerloaded) upon the next access. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
