Revision 38
(checked in by fumanchu, 8 years ago)
|
1. Added Unit.first(farClass, **kwargs) method to retrieve a single related Unit.
2. Fixed doc bug in related_units.
3. associate() is now module-level, not a method of arena. Arenas discover associations when each Unit is registered.
4. Added Arena.register_all().
5. Doc updates.
6. Added engines.register_classes(arena) function.
7. Rewrote tests to import common zoo module.
