SQLAHelper is a small library for SQLAlchemy web applications. It was written for Pyramid but is not framework-specific. It acts as a container for the application's contextual session, engines, and declarative base. This avoids circular dependencies between the application's model modules, and allows cooperating third-party libraries to use the session, base, and transaction.
The contextual session is initialized with the ZopeTransactionExtension so that it can be used with transaction managers. This can be disabled if desired.
It's currently tested on Python 2.7/Linux but should work on 2.5 and other platforms. A set of unit tests is included. Python 3 compatibility is unknown but will be addressed soon.
Documentation is in the 'docs' directory.
