I am very pleased to announce that version 0.4.0 of Elixir is now available. As always, feedback is very welcome, preferably on Elixir mailing list. Highlights for this release ------------------------------------- - Implemented a new attribute-based syntax to declare fields and relationships, which is much closer to what is found in other Python ORM's. - Full support for SQLAlchemy 0.4 - Implemented polymorphic single-table inheritance as well as polymorphic and non-polymorphic multi-table (aka joined table) inheritance. - Added versioning extension to keep track to all changes to your entities by storing them in a secondary table. - Extended documentation (tutorial and others). Please see http://elixir.ematia.de/trac/wiki/Migrate03to04 for detailed upgrade notes. The full list of changes can be seen at: http://elixir.ematia.de/trac/browser/elixir/tags/0.4.0/CHANGES What is Elixir? --------------------- Elixir is a declarative layer on top of the SQLAlchemy library. It is a fairly thin wrapper, which provides the ability to create simple Python classes that map directly to relational database tables (this pattern is often referred to as the Active Record design pattern), providing many of the benefits of traditional databases without losing the convenience of Python objects. Elixir is intended to replace the ActiveMapper SQLAlchemy extension, and the TurboEntity project but does not intend to replace SQLAlchemy's core features, and instead focuses on providing a simpler syntax for defining model objects when you do not need the full expressiveness of SQLAlchemy's manual mapper definitions.
