sorry if this is a faq. I want to use sqlalchemy in a Paste (wsgi) application.
For each web request, I need to begin a transaction, then either commit it or rollback depending on wether an exception occurred. I want the begin / commit / rollback will be handled by some wsgi middleware. Looking at the latest online docs, I'm assuming that "begin" is implicitely handled as needed by the engine. And that if objectstore.commit() is not called, then the engine doesn't commit. But then, neither will it rollback.. Right? But depending on the concurency of the database, this may cause other clients to be blocked while they wait to see if I'm going to modify some data that has been read from some table. So, should I use engine.begin() , objectstore.commit() + engine.commit() and engine.rollback() in the middleware instead? -- Brad Clements, [EMAIL PROTECTED] (315)268-1000 http://www.murkworks.com AOL-IM or SKYPE: BKClements ------------------------------------------------------- Using Tomcat but need to do more?
