dictalchemy3 adds asdict() and fromdict() methods to SQLAlchemy declarative models.
dictalchemy was written by Daniel Holmstrom with contributions from Rob Hardwick and Mike Klimin.
dictalchemy3 is just a fork of the original project to make the code more modern (remove Python 2 support) and compatible to latest SQLAlchemy and setuptools versions. The API and functionality remain completely unchanged, so that it is a drop in replacement for the original dictalchemy.
