Re: [pylons-discuss] Relationship between requests and Zope transactions

Thank you Mike for the information, that all makes sense. I ended up with the same approach that SQLA takes: a “Session” object owned by a DataManager, joined to the Request’s TransactionManager. And then just pass a `dbsession` and `fnsession` and `jobsession` around to functions as needed.

Re: [pylons-discuss] Relationship between requests and Zope transactions

Maybe some background… the reason why I asked the initial question is because a few (and a growing number of) request handlers are complex; that is, they call multiple function levels deep. Now request.dbsession, for example, is SQLA’s current DB session tied to the request’s transaction. To
