(checked in by fumanchu, 8 years ago)

Fix for #20 (awareness of to-one or to-many).
- Magic Unit relation methods may now return a single Unit (or None) if they are to-one. To-many methods still return a list.
- dejavu.associate is replaced by Unit.associate, one_to_many, one_to_one, and many_to_one.
- Unit.first is removed.
- One-way associations are now possible via dejavu.ToOne? and .ToMany?. Customization of relation descriptors is easier (override UnitAssociation?.related).
- Unit._associations dict has changed protocol.
- Lots of module breakouts to make reading easier.
|
- Property svn:eol-style set to
native
